European Alternatives to Pinecone, Milvus and MongoDB Atlas Vector Search - Vector Databases (2026) | European Purpose

European Vector Databases Alternatives

A vector database stores the numeric embeddings behind semantic search, retrieval-augmented generation and recommendations, which makes it the place where your documents and customer data end up in a new form.

This list covers eleven European options: seven purpose-built search and vector engines from Germany, the Netherlands, Norway, France and the United Kingdom, and four European cloud providers that offer vectors through pgvector or OpenSearch. Each is a European alternative to Pinecone, Milvus or MongoDB Atlas Vector Search, and each entry names the contracting entity as the vendor publishes it.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect the order in which tools appear; it never affects whether a tool is listed. Editorial policy

Key takeaways

  • Qdrant ranks #1 among the European vector databases in this directory, because it is purpose-built for vector search, registered as a German GmbH in the Berlin commercial register (HRB 235335 B), and offers a free single-node tier that stays free.
  • Of the eleven, seven are legal entities in the EU (Qdrant in Germany, Weaviate and Elastic in the Netherlands, Meilisearch, OVHcloud and Scaleway in France, Aiven in Finland), one is in Norway and so inside the EEA (Vespa), and three are outside the EEA: SurrealDB and Manticore Search in the United Kingdom and Exoscale in Switzerland.
  • Seven are search or vector engines in their own right. Four are cloud providers that offer vectors through pgvector or OpenSearch k-NN, which suits teams that already run PostgreSQL and want one fewer database.
  • Elastic N.V. is incorporated in Amsterdam, but it is a large company with operations well beyond Europe, so a European legal entity does not by itself mean a European-only operation. The entry says so.
  • Prices are shown only where the vendor publishes them in plain page text: Qdrant and Weaviate have free tiers, Weaviate Flex starts at $45 a month, Meilisearch Cloud at $20 a month, Aiven at $5 a month and SurrealDB Cloud at $0.021 an hour for a second instance.

A European vector database stores and searches embeddings, the numeric representations that power semantic search, retrieval-augmented generation and recommendations, and is run by a company established in the EU, the EEA, the United Kingdom or Switzerland. This directory lists eleven.

Seven are purpose-built search or vector engines (Qdrant, Weaviate, Vespa, Elasticsearch, Meilisearch, SurrealDB and Manticore Search) and four are European cloud providers that host vectors through the pgvector extension or OpenSearch (Aiven, OVHcloud, Scaleway and Exoscale). Each entry states the contracting entity as the vendor publishes it, so a compliance review can start from the right legal name.

Every European vector database reviewed

#1 Qdrant

Berlin, Germany Free tier forever (single-node cluster, 0.5 vCPU, 1 GB RAM, 4 GB disk) / Standard usage-based, 99.5% uptime SLA / Premium requires a minimum spend, 99.9% uptime SLA Free tier, forever

Best for: Teams building semantic search or RAG on a German vendor

  • Operating company. Qdrant Solutions GmbH, HRB 235335 B Amtsgericht Berlin-Charlottenburg
  • Jurisdiction. EU (Germany)
  • Where the data sits. Qdrant Cloud, region chosen by the customer; Hybrid Cloud and on-premise options are listed on the pricing page
  • Source code. Open source
  • Replaces. Pinecone, Milvus, MongoDB Atlas Vector Search

Qdrant is a purpose-built vector database, open source, that a team can self-host or run on Qdrant Cloud. The pricing page lists a free tier of a single-node cluster with 0.5 vCPU, 1 GB RAM and 4 GB disk that is free forever, a usage-based Standard tier for production with dedicated resources and a 99.5% uptime SLA, and a Premium tier with a minimum spend, SSO, private VPC links and a 99.9% SLA.

The legal picture is clear. Qdrant Solutions GmbH publishes an impressum with its address at Chausseestrasse 86 in Berlin, the register entry HRB 235335 B at the Berlin-Charlottenburg court and André Zayarni as representative. The terms name Qdrant Solutions GmbH as the company and apply the law of Germany. A single-purpose engine is the point: it is narrower than a general-purpose database, and the managed cloud, rather than a broad platform, is what you buy.

What Qdrant does well

  • German GmbH with a full imprint and commercial-register number
  • Free single-node tier that stays free
  • Open source, so self-hosting on European servers is possible
  • Dedicated purpose-built vector engine
  • Terms governed by the law of Germany

Where Qdrant falls short

  • Single-purpose: not a general-purpose database
  • Standard and Premium prices are usage-based or on request
  • Region list is not on the pricing page
  • The free tier is small at 4 GB disk

Standout feature. A German, open-source vector engine with a permanent free tier and a published register entry.

#2 Weaviate

Amsterdam, Netherlands Free tier $0/month (100,000 objects, 1 cluster per user) / Flex from $45/month pay-as-you-go / Premium prepaid contract, contact sales Free tier, no credit card required

Best for: Teams wanting hybrid search from a Dutch vendor

  • Operating company. Weaviate B.V.
  • Jurisdiction. EU (Netherlands)
  • Where the data sits. Weaviate Cloud on AWS, GCP and Azure with global coverage; the pricing page does not list the regions
  • Source code. Open source
  • Replaces. Pinecone, Milvus, MongoDB Atlas Vector Search

Weaviate is the second purpose-built vector database here, and its pricing page lists a free tier at $0 a month with 100,000 objects, 1 GB memory and one cluster per user, a Flex plan from $45 a month on pay-as-you-go, and a Premium prepaid contract on request. Embeddings and a Query Agent are offered as services inside Weaviate Cloud, and the plans mention coverage on AWS, GCP and Azure.

The privacy policy is issued by Weaviate B.V., a private limited company at Prinsengracht 769A in Amsterdam, and names the Dutch Data Protection Authority. Compared with Qdrant, the cloud runs on the three US hyperscalers, which is a point to check against your own requirements, and the pricing page does not list the regions. For teams that want a Dutch contracting party and a hybrid-search engine, it is a sound choice.

What Weaviate does well

  • Dutch B.V. named in the privacy policy
  • Free tier with 100,000 objects
  • Flex plan from $45 a month with no commitment
  • Open-source core
  • Built-in embeddings and query services

Where Weaviate falls short

  • Cloud runs on AWS, GCP and Azure
  • Regions are not listed on the pricing page
  • Premium is quoted on request
  • Free tier allows one collection and three tenants

Standout feature. A Dutch-registered, open-source vector database with hybrid search and a $45 entry plan.

#3 Vespa

Trondheim, Norway Vespa Cloud pricing is not shown on the pricing page; free trial and contact form only Free trial

Best for: Large-scale search and ranking beyond plain vector similarity

  • Operating company. Vespa.ai AS, organisation number 931605569, Bronnoysund register
  • Jurisdiction. Norway (EEA, not EU)
  • Where the data sits. Not stated on the pages checked
  • Replaces. Pinecone, Elasticsearch, Algolia

Vespa describes itself as letting you query, organise and make inferences in vectors, tensors, text and structured data, scaling to billions of items and thousands of queries per second. Its vector-database page stresses hybrid ranking over lexical, semantic and structured signals in one pipeline, and multi-vector representations. It is the heaviest engine in this directory, aimed at teams whose search quality depends on custom ranking.

The privacy policy names Vespa.ai AS as data controller for its websites and for Vespa Cloud contracts, and the Norwegian Bronnoysund register lists VESPA.AI AS in Trondheim, organisation number 931605569. Norway is inside the EEA but not the EU. The pricing page shows no amounts, only a free trial and a contact form, and the licence was not stated on the pages checked.

What Vespa does well

  • Norwegian company in the official register
  • Hybrid ranking and multi-vector support in one engine
  • Scales to billions of documents by its own account
  • Free trial of Vespa Cloud

Where Vespa falls short

  • No prices published
  • More complex than a simple vector store
  • Norway is in the EEA but not the EU
  • Licence not stated on the pages checked

Standout feature. A Norwegian engine for teams where ranking, not just vector similarity, decides search quality.

#4 Elasticsearch (Elastic)

Amsterdam, Netherlands Elastic Cloud Serverless and Hosted, free trial; amounts are not in the server-rendered pricing page Free trial

Best for: Teams already running Elasticsearch who want vectors in the same engine

  • Operating company. Elastic N.V., Keizersgracht 281, 1016 ED Amsterdam (per its privacy statement)
  • Jurisdiction. EU (Netherlands)
  • Where the data sits. Elastic Cloud on major clouds; regions not verified here
  • Replaces. Pinecone, Algolia, MongoDB Atlas Search

Elastic markets Elasticsearch as a vector database with hybrid search, metadata filters in a single call and Better Binary Quantization claiming up to 95% memory savings. Since Elastic acquired Jina AI in October 2025, Jina models are offered for embeddings and reranking inside Elastic. Deployment options are Elastic Cloud Serverless, Elastic Cloud Hosted and self-managed Elasticsearch.

Elastic N.V. gives an Amsterdam address (Keizersgracht 281) in its privacy statement and says the statement covers the company and its subsidiaries. That makes the parent Dutch, but it is a large company with offices worldwide, and the contracting entity in an order form depends on the customer, which was not verified here. The server-rendered pricing page carries no amounts.

What Elasticsearch (Elastic) does well

  • Dutch parent company with an Amsterdam address
  • Familiar engine for existing Elasticsearch users
  • Hybrid search and quantization built in
  • Serverless, hosted and self-managed options

Where Elasticsearch (Elastic) falls short

  • Large company with operations well beyond Europe
  • Contracting entity per customer not verified
  • No amounts on the pricing page text
  • Broader and heavier than a pure vector store

Standout feature. The incumbent search engine from a Dutch parent company, now with vectors and hybrid search built in.

#5 Meilisearch

Paris, France Cloud from $20/month (14-day trial) / usage-based plan $30/month base (100K docs, 50K searches) / resource-based from $23/month / Enterprise on request 14-day free trial, no credit card required

Best for: Product search that blends keywords and meaning

  • Operating company. Meili SAS, RCS Paris 844 156 364
  • Jurisdiction. EU (France)
  • Where the data sits. Meilisearch Cloud regions are listed on a separate page; self-hosting is available
  • Source code. Open source
  • Replaces. Algolia, Pinecone, Elasticsearch

Meilisearch began as a typo-tolerant full-text engine and now lists vector and hybrid search, federated search and conversational AI among its features. It is open source and also sold as Meilisearch Cloud, with a 14-day trial, a usage-based plan at $30 a month for 100,000 documents and 50,000 searches, a resource-based XS instance at $23 a month, and an Enterprise plan on request.

The terms say Meilisearch is developed by Meili, a simplified joint-stock company under French law, registered in Paris under number 844 156 364, and that French law and the Paris courts apply. It is a better fit for site and app search than for a very large embedding store, which is where Qdrant, Weaviate and Vespa are stronger.

What Meilisearch does well

  • French company, French law and Paris courts in the terms
  • Hybrid search combining keywords and vectors
  • Open source and self-hostable
  • Prices published, from $20 a month

Where Meilisearch falls short

  • Built for search products, not very large vector stores
  • Cloud regions are not on the pricing page text
  • Enterprise plan quoted on request
  • Pricing is in US dollars

Standout feature. A French open-source search engine that adds vectors to typo-tolerant search with prices published from $20 a month.

#6 SurrealDB

London, United Kingdom Cloud: first instance $0/hr with 1 GB storage free / further instances from $0.021/hr, compute and storage priced separately / Enterprise on request Free instance

Best for: Teams wanting vectors, graph and documents in one database

  • Operating company. SurrealDB Ltd, company no. 13615201, England and Wales
  • Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
  • Where the data sits. Not stated on the pages checked
  • Replaces. Pinecone, MongoDB, Neo4j

SurrealDB combines graph, vector, document, relational and full-text search in one engine and one query language, and positions its newer Agent Memory layer for AI agents. The Cloud pricing page lists a first instance at $0 an hour with 1 GB of storage free, further instances from $0.021 an hour, compute and storage priced separately, and an Enterprise plan.

The site footer states that SurrealDB Ltd is registered in England and Wales, company number 13615201, with a registered address in Altrincham and a trading address in London. The United Kingdom is outside the EU and the EEA, though it holds an EU adequacy decision. It is a multi-model database more than a dedicated vector store, so it suits applications that need several data models together.

What SurrealDB does well

  • Vectors, graph and documents in one engine
  • Free first Cloud instance
  • Hourly pricing is published
  • Company number and addresses stated on the site

Where SurrealDB falls short

  • UK entity, outside the EU and EEA
  • Not a dedicated vector database
  • Licence not stated on the pages checked
  • Data location not stated on the pages checked

Standout feature. A British multi-model database that puts graph, document and vector search behind one query language.

#8 Aiven

Helsinki, Finland PostgreSQL and OpenSearch: Free $0/month / Developer $5/month / Hobbyist from $12/month / Startup from $75/month Free plan, plus a free 30-day trial of larger plans

Best for: Managed PostgreSQL with pgvector or OpenSearch k-NN, EU-based

  • Operating company. Aiven Oy, business ID 2795743-5 (PRH)
  • Jurisdiction. EU (Finland)
  • Where the data sits. Customer-chosen cloud and region; free plans cannot select a region
  • Source code. Closed source
  • Replaces. Pinecone, Elastic Cloud, AWS RDS with pgvector

Aiven is not a vector database in itself. It runs managed open-source data services, and two of them cover vectors: PostgreSQL lists the pgvector extension among its available extensions, and OpenSearch lists k-NN among its plugins. The pricing page shows a free plan, a Developer plan at $5 a month, Hobbyist from $12 and Startup from $75, plus a free 30-day trial of larger plans.

Aiven Oy is in the Finnish business register (business ID 2795743-5), and the terms are governed by Finnish law with arbitration in Helsinki. For a team that already uses PostgreSQL, adding pgvector at a European provider keeps the stack simple. The cost is that it is not tuned for very large vector workloads the way Qdrant or Vespa are.

What Aiven does well

  • Finnish company in the official register
  • Free plan and $5 Developer plan published
  • pgvector in PostgreSQL and k-NN in OpenSearch
  • Terms under Finnish law

Where Aiven falls short

  • A general platform, not a dedicated vector engine
  • Free plans cannot choose a region
  • Multi-cloud, so the underlying hyperscaler matters
  • Prices are in US dollars

Standout feature. The simplest route to pgvector or OpenSearch k-NN from a Finnish company with published plans from $0.

#9 OVHcloud

Roubaix, France Managed PostgreSQL billed per hour by plan; no vector-specific price on the page

Best for: pgvector on a French cloud, with Qdrant as a partner option

  • Operating company. OVH SAS, 2 rue Kellermann, 59100 Roubaix (OVH Groupe SA, 537 407 926 RCS Lille Metropole)
  • Jurisdiction. EU (France)
  • Where the data sits. Customer-chosen region; OVHcloud lists European data centres
  • Source code. Closed source
  • Replaces. Pinecone, AWS RDS with pgvector

OVHcloud's PostgreSQL page names pgvector and pgvectorscale for storing, indexing and searching vector representations for AI, and also mentions Qdrant as a partner solution. This is vector search as a feature of managed PostgreSQL, not a separate product, so it suits teams that already run on OVHcloud.

The Public Cloud terms refer to OVH Groupe SA affiliates (537 407 926 RCS Lille Metropole, 2 rue Kellermann, 59100 Roubaix), and the page footer names OVH SAS. The company is French, and no vector-specific price is given on the page. Compared with Aiven, OVHcloud is an infrastructure provider first, with a wider catalogue and a heavier console.

What OVHcloud does well

  • French company with a published register number
  • pgvector and pgvectorscale named on the page
  • Qdrant offered as a partner solution
  • Part of a full European cloud catalogue

Where OVHcloud falls short

  • No vector-specific price on the page
  • Not a dedicated vector database
  • Several OVH group entities appear in the terms
  • Wider console than a single-purpose service

Standout feature. A French infrastructure provider that offers pgvector and a Qdrant partner option next to its other cloud services.

#10 Scaleway

Paris, France Managed PostgreSQL billed by usage; no vector-specific price on the page

Best for: Turning a French managed PostgreSQL into a vector database

  • Operating company. Scaleway SAS (Iliad Group)
  • Jurisdiction. EU (France)
  • Where the data sits. Paris, Amsterdam and Warsaw regions per the existing Scaleway entry on this site
  • Source code. Closed source
  • Replaces. Pinecone, AWS RDS with pgvector

Scaleway's database page says you can turn your database into a vector database with pgvector, alongside PostgreSQL extensions such as TimescaleDB and PostGIS, and that you pay for what you use with no up-front commitment. As with Aiven and OVHcloud, this is vector search inside a general managed database.

The page footer names Scaleway SAS. The company belongs to the Iliad Group, based in Paris. No vector-specific price is quoted on the page. For a small RAG feature in an application already on Scaleway it is the lowest-friction option; for a large embedding workload a purpose-built engine fits better.

What Scaleway does well

  • French company, footer names Scaleway SAS
  • pgvector offered on managed databases
  • Usage-based, no up-front commitment
  • Fits teams already on Scaleway

Where Scaleway falls short

  • Not a dedicated vector database
  • No vector-specific price on the page
  • Register number not checked on the pages read
  • Less specialised than Qdrant or Weaviate

Standout feature. The lowest-friction pgvector option for teams already on a French cloud.

#11 Exoscale

Lausanne, Switzerland Managed databases priced per hour in EUR, CHF or USD on the pricing page; pgvector is an extension of managed PostgreSQL, no separate price

Best for: pgvector under Swiss law with European data centres

  • Operating company. Akenes SA (Exoscale), Boulevard de Grancy 19A, CHE-423.524.322
  • Jurisdiction. Switzerland (adequacy decision, outside the EEA)
  • Where the data sits. Swiss law governs the terms; data-centre locations as listed on the existing Exoscale entry
  • Source code. Closed source
  • Replaces. Pinecone, AWS RDS with pgvector

Exoscale's product menu lists Vector Databases under its AI storage section, with pgvector described as vector similarity search inside PostgreSQL and Vector Search as semantic search over your own data. Managed databases are priced per hour on the pricing page in EUR, CHF or USD, and pgvector is an extension, not a separate product.

The terms name Akenes SA, Boulevard de Grancy 19A, Lausanne, as the supplier, apply the laws of Switzerland with the courts of the canton of Vaud, and the footer gives the registration CHE-423.524.322 and states that Exoscale is a member of A1 Digital. Switzerland is outside the EU and EEA, though it holds an EU adequacy decision.

What Exoscale does well

  • Swiss supplier named with a registration number
  • pgvector and vector search listed as products
  • Prices in EUR, CHF or USD
  • Terms under Swiss law

Where Exoscale falls short

  • Switzerland is outside the EU and EEA
  • Not a dedicated vector database
  • Part of A1 Digital, a larger group
  • No vector-specific price

Standout feature. A Swiss managed-PostgreSQL provider that lists vector databases as a product and prices in francs or euros.

What does a European vector database actually need to prove?

A vector database holds embeddings, and embeddings are derived from your documents, support tickets or customer records. That makes the contracting entity and the data location the two facts that matter. The entity is the company whose terms you sign and whose privacy policy governs the service. The location is where the index sits, which for a managed service is a region you choose or the vendor chooses for you.

This directory checks the first against the vendor's own imprint, terms or privacy policy, or an official register. Qdrant publishes a German impressum with a Berlin commercial-register number, Weaviate's privacy policy names Weaviate B.V. in Amsterdam, and Vespa.ai AS is in the Norwegian register in Trondheim. The second is stated less often, and where a vendor does not state it, the entry says so.

Purpose-built engine or pgvector on a European cloud?

A purpose-built engine such as Qdrant, Weaviate or Vespa is designed around approximate nearest-neighbour search, filtering and hybrid ranking, and is the usual choice when vector search is the core workload or the index is large. Meilisearch and Manticore Search come from full-text search and add vectors and hybrid queries on top, which suits products where keyword and semantic results must be blended.

pgvector inside managed PostgreSQL is the simpler answer when the vectors are a feature of an existing application. Aiven lists pgvector among its PostgreSQL extensions and k-NN among its OpenSearch plugins. OVHcloud and Scaleway both name pgvector on their database pages, and Exoscale lists pgvector and vector search under its managed databases. The trade-off is that a general-purpose database is not tuned for very large vector indexes.

Which of these are open source, and does it matter?

Qdrant, Weaviate, Meilisearch and Manticore Search are open source, which means a team can self-host them on European infrastructure and keep the vendor's cloud out of the picture. That is the strongest sovereignty position, because the data never touches a vendor service. The licence terms of Vespa, Elasticsearch and SurrealDB were not stated on the pages checked for this entry, so none is claimed here.

For the four cloud providers, the database engine (PostgreSQL, OpenSearch) is open source, while the managed service is a commercial product. What you buy is operation, backups and support under a European contract.

What about the three that sit outside the EEA?

SurrealDB Ltd and Manticore Software Ltd are registered in England and Wales, and Akenes SA, which runs Exoscale, is a Swiss company. The United Kingdom and Switzerland are covered by EU adequacy decisions for personal data transfers, which is why they are included, but they are not EU member states and the entries mark them as such.

For a team that needs an EU-registered counterparty specifically, the seven EU-registered vendors are Qdrant, Weaviate, Elasticsearch, Meilisearch, Aiven, OVHcloud and Scaleway. Vespa is registered in Norway, which is inside the EEA.

How should a team pick one?

Start with the workload. A retrieval-augmented generation prototype fits a free tier: Qdrant and Weaviate both publish one, and Aiven's free PostgreSQL plan is an option for pgvector. A search product that must blend keywords and meaning looks at Meilisearch, Manticore Search, Elasticsearch or Vespa. A team that already runs PostgreSQL at a European cloud provider can try pgvector there first.

Then check the contract. Ask which entity signs, where the index is stored, and whether the vendor offers a data processing agreement. The pricing pages here are the starting point, and several enterprise plans (Weaviate Premium, Vespa Cloud, Elastic) are quoted on request.

How we selected and ranked these 11 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

  1. Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
  2. Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
  3. Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
  4. Editorial review. Three people touch every page: one writes it, a second edits it, and a third checks the compliance and pricing claims against the vendor's documentation. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Qdrant holds #1 in this directory because it is purpose-built for vector search, is registered in Berlin as Qdrant Solutions GmbH and has a free tier that stays free. Weaviate (Amsterdam) is the closest alternative with hybrid search, and Vespa (Trondheim) suits very large, ranking-heavy search. The best fit depends on the workload.

Yes. Qdrant (Germany) and Weaviate (Netherlands) are the closest purpose-built managed alternatives, each with a free tier. Vespa (Norway) is a larger-scale option, and Aiven, OVHcloud, Scaleway and Exoscale offer vectors through pgvector inside managed PostgreSQL.

Qdrant, Weaviate, Meilisearch and Manticore Search describe themselves as open source on their own pages. The PostgreSQL and OpenSearch engines behind the cloud providers are open source too. Licence terms for Vespa, Elasticsearch and SurrealDB were not stated on the pages checked.

Qdrant has a free single-node cluster that stays free, and Weaviate has a free tier with 100,000 objects. Aiven has a free plan for PostgreSQL and OpenSearch, SurrealDB Cloud lists a free first instance, and Meilisearch Cloud has a 14-day trial.

Yes. Aiven lists pgvector in its PostgreSQL extensions, OVHcloud names pgvector and pgvectorscale on its PostgreSQL page, Scaleway says you can turn a managed database into a vector database with pgvector, and Exoscale lists pgvector under its managed databases.

No. Seven are EU-registered (Qdrant, Weaviate, Elasticsearch, Meilisearch, Aiven, OVHcloud, Scaleway), Vespa is Norwegian and so inside the EEA, and SurrealDB, Manticore Search and Exoscale are in the United Kingdom or Switzerland.

Elastic N.V. gives an Amsterdam address in its privacy statement, so the parent company is Dutch. It is a large company with operations well beyond Europe, so read the contracting entity in your own order form. Elastic documents a vector database offering with hybrid search and Better Binary Quantization.

It depends on the vendor. Qdrant Cloud stores data in the deployment region you choose. Weaviate Cloud runs on AWS, GCP and Azure. Aiven lets you choose a cloud and region on paid plans. Vespa, SurrealDB and Elasticsearch do not state it on the pages checked, so ask before you sign.

Qdrant, Weaviate, Meilisearch and Manticore Search are open source and can run on your own European servers. Self-hosting removes the vendor cloud from the data path, at the cost of running the cluster yourself.
