Nuremberg, Germany
Exasol Personal free for personal use / Exasol Enterprise by quote
Exasol Personal, free for personal use
Best for: Teams needing a fast analytical database with a free edition
Exasol is the most conventional data warehouse in this list: an analytical database, not a service wrapped around someone else's engine. The product page describes use cases for the data warehouse, analytics acceleration and a lakehouse turbo, plus an MCP connection for AI agents, a text AI feature and a semantic layer. Exasol Personal is free for personal use and Exasol Enterprise is sold by quote.
The company is Exasol AG, a stock corporation headquartered in Nuremberg and entered in the commercial register of the Nuremberg local court under HRB 23037, with Jörg Tewes as chairman of the executive board. The privacy policy names group companies in Germany, the UK, France and Switzerland, and also Exasol INC in the USA, which is worth knowing for a sovereignty brief.
The product pages checked do not state a data location, and no price is published for Enterprise, so cost and residency are questions for a sales call.
What Exasol does well
- German AG with full imprint and commercial register number
- Dedicated analytical database rather than a wrapped engine
- Free Exasol Personal edition for personal use
- Deployment options include on-premises, cloud and hybrid
- MCP connection for AI agents is listed
Where Exasol falls short
- Enterprise pricing is not published
- Group includes an American company, Exasol INC
- Data location is not stated on the product page
- Commercial product, not open source
Standout feature. It is the only entry here that is a dedicated analytical database from a German AG with a free edition for personal use.
Paris, France
Pay for use; no price shown on the product page
Best for: Teams wanting managed ClickHouse hosted only in Europe
Scaleway Data Warehouse for ClickHouse is a fully managed warehouse built to run analytics at scale without managing clusters. Resource allocation for vCPU and RAM adjusts automatically with the workload, storage is allocated without disk sizing, and federated queries read data where it sits instead of copying it. BI tools including Tableau, Power BI Desktop and Metabase are listed as integrations.
Scaleway says the warehouse is hosted exclusively in Europe, with regions in Paris and Milan, and that it works with open standards and no proprietary formats. The legal notice names SCALEWAY, a simplified joint stock company, SIREN 433 115 904, RCS Paris, registered at 8 rue de la Ville-l'Evêque, 75008 Paris.
The product page promises transparent pricing but shows no figure in the page text, so the cost has to be worked out in the console or the pricing page.
What Scaleway Data Warehouse for ClickHouse does well
- French SAS with a full legal notice
- Hosted exclusively in Europe, per the vendor
- Elastic scaling and bottomless storage
- Federated queries without copying data
- Open standards and no proprietary formats stated
Where Scaleway Data Warehouse for ClickHouse falls short
- No price on the product page
- Only two regions listed, Paris and Milan
- Built on ClickHouse, so SQL differs from Snowflake
- Younger service than the ecosystem it competes with
Standout feature. It pairs managed ClickHouse with a vendor statement of exclusive European hosting and federated queries.

Software free and open source under MPL 2.0 / services by quote
Free to download
Best for: Open-source purists and embedded analytics
MonetDB is a column-oriented analytical database that is free and open source under the Mozilla Public License 2.0. MonetDB Solutions describes server, cloud-marketplace and embedded instances, and positions the product for in-database machine learning and a blend of OLTP and OLAP.
The legal picture is Dutch on both sides. MonetDB Solutions B.V. is at Science Park 110, Amsterdam, and sells services. The Stichting MonetDB Foundation, Chamber of Commerce number 92 29 17 08, holds the intellectual property and was established in December 2023 as an independent not-for-profit.
There is no managed warehouse service with a published price, so MonetDB suits teams that will run it or buy support.

- Dutch company and Dutch foundation
- Foundation holds the IP, independent of the vendor
- Server, cloud and embedded options
Where MonetDB falls short

Best for: Organisations that want a German hyperscale-style cloud
The Data Warehouse Service on T Cloud Public, the cloud formerly branded Open Telekom Cloud, consolidates data from many sources for analysis and data mining. The page says sources can be anywhere but are copied to a data centre in Germany, that import from object storage is fast and encrypted transfer is possible, and that the cluster supports Java UDFs and IAM roles. Billing is pay-per-use.
The imprint names T-Systems International GmbH, registered at the Frankfurt am Main district court under HRB 55933, with a business address in Bonn. A EUR 250 starting credit is offered until 31 December 2026, and list prices are in a service description PDF.
The page does not name the engine behind the service, so engine and SQL compatibility need to be asked about before a migration.

- IAM roles and encrypted import
- EUR 250 starting credit

The pricing page says the fee is a fixed monthly subscription based on edition, number of environments and concurrency sizing, not on data volume, and that adding users does not raise it.
The privacy policy names ADE Insights Oy as data controller, at Eteläesplanadi 8, 00130 Helsinki, and the site footer gives a Helsinki address. No figure is published.
