European Alternatives to OneTrust
Looking for a European alternative to OneTrust? OneTrust's published contracting table puts North American customers with OT Technology, Inc. in Atlanta under Georgia law, and European customers with a Spanish subsidiary whose contract is governed by English law and English courts, while the group relies on the EU-US Data Privacy Framework for transfers.
Eleven European consent platforms cover the cookie banner and consent-record part of the job, from companies in Germany, France, Italy, Sweden, Lithuania, the Netherlands and Denmark: enterprise platforms, per-site subscriptions and WordPress plugins. None of them replaces OneTrust's wider privacy, risk and AI-governance suite.
How we rank these tools — 4-step process
-
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
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
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
Position on this page
Placement on this page can be paid, and that can affect which tools appear here and the order they appear in. It never buys a good review: 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 which tools appear here and the order they appear in. Editorial policy

Key takeaways
- OneTrust's published contracting table gives Europe, the Middle East and Africa (except the UK) a Spanish contracting entity, with the laws and courts of England and Wales, and the Americas an Atlanta entity under Georgia law.
- Usercentrics (Munich) publishes plans from €7 a month and a 14-day trial with no credit card, and also owns the Cookiebot brand.
- iubenda (Milan) starts at €4.99 per site per month on annual billing and bundles generated privacy and cookie policies with the banner.
- CookieScript (Vilnius) has a free plan and a Lite plan at €6 a month; consentmanager (Sweden) prices by page views from €23 a month.
- Didomi (Paris) and Cookie Information (Copenhagen) are the enterprise-grade answers, and both quote prices per organisation.
- Borlabs Cookie and Complianz are WordPress plugins, and Klaro has an open-source core: pick them only if your site fits that shape.
Why people leave OneTrust
OneTrust is the best-known consent management platform. It started as a cookie banner and grew into a suite that also covers privacy rights requests, vendor risk, data mapping, governance and AI oversight. Large companies buy it as one system for the whole privacy team, which is why it shows up in so many tenders.
It is run by OneTrust LLC in Atlanta. The contracting table on its legal page assigns the contracting entity by where the customer is based: OT Technology, Inc. in Atlanta, under Georgia law, for the Americas, and OT Technology Spain S.L.U. in Madrid for Europe, the Middle East and Africa, except the UK, Guernsey and Jersey.
That Spanish contract is governed by the laws of England and Wales, with the courts of England and Wales. The UK is outside the EU.
For data leaving the EU, OneTrust says it relies on adequacy decisions, including its own self-certification under the Data Privacy Framework, and on standard contractual clauses where there is none. That is a lawful route, but it is a route that depends on a framework which has been challenged before. This page is about the consent part only: the banner, the script blocking and the consent record. Eleven European platforms do that job.
- The contract is Spanish, the law is English If you are in the EU, your counterparty is a Spanish subsidiary, but the governing law and the courts named in OneTrust's contracting table are those of England and Wales. A dispute would not be decided in your own legal system. With the platforms below, the contracting entity sits in an EU country, with the exception of Borlabs, where the order itself goes through Paddle as merchant of record.
- Transfers rest on a framework, not on geography OneTrust states that it relies on adequacy decisions, including its Data Privacy Framework self-certification, and on standard contractual clauses otherwise. A European consent platform that hosts in the EU does not need that route for its own processing. That does not make it better at the job, but it removes one assumption from your records of processing.
- You may be buying a suite for a banner OneTrust is built for privacy teams with data mapping, assessments and vendor risk on top of consent. A company that needs a compliant banner, script blocking, a consent log and Google Consent Mode may pay for far more than it uses. Several European tools below publish a price per site or per month, which OneTrust's legal pages do not.
- The European answers are not one product Didomi and Cookie Information are enterprise platforms in the same bracket as OneTrust's CMP. Usercentrics, iubenda, CookieScript, consentmanager, Axeptio and CookieFirst are subscription CMPs for small and mid-sized sites. Borlabs Cookie and Complianz run inside WordPress, and Klaro has an open-source core. Four of the eleven (iubenda, consentmanager, CookieFirst and Complianz) sit in one group, so they are less independent of each other than their names suggest.
What you have to replace, not just match
Start by listing what you use OneTrust for. If it is only the banner and the consent record, any tool here will do and the switch is a weekend. If it also runs your data subject request portal, your vendor assessments or your records of processing, the consent part moves and the rest does not, so plan a second tool or stay with OneTrust for those modules.
Before you switch, export your consent logs and keep them for as long as your retention policy says. A new platform starts a new record, and you may be asked for the old one. Rebuild your cookie categories from a fresh scan rather than copying the old list, run the old and new banner on a staging site, and check that scripts are blocked before consent, not after.

- Independently checked. IAB TCF registered CMP.
Best for: Businesses of any size that want a hosted CMP with prices they can read and a trial before buying

Its pricing page shows Essential at €7 a month and says a 14-day free trial is available on all plans with no credit card. It sells the consent platform for web, app and connected TV, and a privacy policy generator, which is a wider range than most of the others here.

- Independently checked. IAB TCF registered CMP.
Best for: Companies with a compliance function that need documented consent at scale
Cookie Information is a Danish company (CVR DK-38758292), according to this site's tool page. The company number was not re-checked at its own legal page for this comparison.
It is an IAB TCF registered CMP with multi-domain management and reporting, and it has been selling consent tools since 2013. Pricing is quoted per organisation, so a demo is the first step.
What Cookie Information does better than OneTrust
- Danish company inside the EU
- Strong audit trail and documentation of what each visitor chose
- Multi-domain management and reporting for larger setups

Klaro is made by KIProtect GmbH in Berlin (HRB 208395B, as recorded on this site's tool page). Its client-side core is open source under a BSD licence, and hosted tiers add scanning and server-side consent records.

Best for: WordPress site owners who want nothing sent to the vendor
Borlabs GmbH is at Hamburger Str. 11 in Hamburg, registered at Amtsgericht Hamburg under HRB 171030, according to its legal notice. Its site says orders are handled by Paddle as merchant of record, so the purchase contract runs through Paddle and you should check its details at checkout.
The site shows prices from €49, with a 30-day money-back guarantee instead of a trial. It is a WordPress-only plugin and the consent records stay on your own install.
What Borlabs Cookie does better than OneTrust

Best for: WordPress sites that want a free start and automatic cookie detection
Complianz B.V. is in Groningen (KvK 717814475, as recorded on this site's tool page), and iubenda's site lists it as a group company. The company number was not re-checked at its own site for this comparison.
It is a WordPress plugin that detects the services a site uses, blocks them before consent and generates a cookie policy and other legal documents from the result. A free version exists. Its pricing page shows different currency figures that could not be reconciled, so no amount is quoted.
What Complianz does better than OneTrust
- Free version available
- Dutch B.V. inside the EU
- Generates legal documents from the scan result
Where Complianz is a step down from OneTrust
- WordPress only, so unusable on other platforms
- Prices not quoted because the page shows several currencies
- Part of the iubenda group
Standout against OneTrust. Deep WordPress integration with a free entry point.
What actually breaks when you switch
Moving a banner is easy. Moving the record is not. Your new platform will not import OneTrust's consent log, so export it first and keep it as long as your retention policy says. Expect the first weeks to show a dip in consent rates while visitors see a new banner.
If OneTrust also handles your privacy requests, assessments or vendor reviews, leaving only the consent module leaves those with it. Decide whether you want a second tool, a spreadsheet, or to stay put for those modules.
Check how each tool handles TCF, Google Consent Mode and server-side tagging on the plan you need. Features that look standard on a feature page often start at a higher tier.
Is there a European tool that does everything OneTrust does?
No. OneTrust covers consent, privacy requests, assessments, vendor risk, data mapping and AI governance in one suite. The closest European match for the consent and TCF side at enterprise scale is Didomi, with Cookie Information in the same bracket. Neither is a full privacy-management suite in OneTrust's sense.
If you only need consent, the choice widens a lot, and the cost drops. Check which of OneTrust's other modules you really use before you decide that you need a replacement for them.
Which of these have a free plan or a trial?
CookieScript describes a free plan on its pricing page. Usercentrics offers a 14-day trial on all plans with no credit card, CookieFirst a 14-day trial, and consentmanager a free trial. Complianz has a free WordPress version, and Klaro's open-source client core is free to self-host.
Axeptio publishes a price from €90 a year and offers a free cookie scanner. Borlabs Cookie has a 30-day money-back guarantee instead of a trial. Didomi and Cookie Information are sold through a demo.
I run WordPress. Which should I look at first?
Borlabs Cookie (from €49 a year, running on your own server) and Complianz (scanning, blocking and generated legal documents, with a free version) are built for WordPress and nothing else. The hosted CMPs, such as Usercentrics, iubenda and CookieScript, also work on WordPress through a script or plugin.
The difference is where the consent record lives. A plugin keeps it on your own site. A hosted platform keeps it with the vendor, which helps if you manage many sites and hurts if you wanted nothing to leave your server.
Does the vendor's location matter for a cookie banner?
It matters for two reasons. The banner is the first thing that runs on your site, and its provider sees visitor data. And the consent record is evidence you may need in front of a regulator. A contracting entity and hosting inside the EU keep that evidence and that processing within one legal system.
It is not the only criterion. The platform has to block scripts before consent and keep a usable log. A European address does not substitute for either.
Which one to pick
If you want a hosted consent platform with prices you can read and a trial, Usercentrics is the sensible starting point, with iubenda cheaper if you also want generated privacy policies and CookieScript the one with a free plan. Didomi and Cookie Information are the ones to talk to if you are an enterprise with many brands and programmatic advertising.
WordPress site owners should look at Borlabs Cookie and Complianz first. Klaro suits a team that wants to read the code.
Be realistic about the gap. None of the eleven replaces OneTrust's privacy-request, risk and governance modules, and the argument for leaving is a legal and cost one, not a feature one: a European contracting entity, a record that stays in the EU, and a price list. Four of the eleven share a group, so if independence matters to you, check that before you choose.
Frequently Asked Questions
For most websites, Usercentrics is the best starting point on this page: published prices from €7 a month, a 14-day trial and a German contracting entity. iubenda is better if you also need a generated privacy policy, CookieScript if you want a free plan, and Didomi if you need enterprise-scale TCF and multi-brand management.
No. OneTrust LLC is based in Atlanta. Its contracting table assigns European customers to OT Technology Spain S.L.U. in Madrid, but the governing law and courts named for that entity are those of England and Wales.
According to the contracting entities table on its legal page, customers in Europe, the Middle East and Africa (except the UK, Guernsey and Jersey) contract with OT Technology Spain S.L.U., under the laws of England and Wales and the courts of England and Wales. UK customers contract with OneTrust Technology Ltd. in London, under the same law.
Usercentrics lists Essential at €7 a month. iubenda lists Essentials at €4.99 per site per month on annual billing, up to 25,000 page views a month. CookieScript lists a free plan and Lite at €6 a month. consentmanager lists Starter at €23 a month for 100,000 views, and Axeptio lists €90 a year for up to 30,000 page views a year. Borlabs Cookie starts at €49. Didomi and Cookie Information quote per organisation.
Cookiebot is a brand of Usercentrics, so this page lists Usercentrics. If you use Cookiebot today, Usercentrics is the natural migration path and also the one with published prices.
Didomi, Cookie Information and Usercentrics describe IAB TCF registration, and Axeptio and CookieScript state Google Consent Mode support on their sites. Check the plan you need, because some features only start at higher tiers, and check TCF status in the IAB Europe registry before you rely on it.
iubenda says it is subject to the direction and coordination of team.blue NV and the parent company of consentmanager, CookieFirst and Complianz. Usercentrics owns the Cookiebot brand. The others on this page are independent companies according to their own sites, as far as could be checked.
Export the logs from OneTrust before you cancel and keep them for as long as your retention policy requires. Most platforms start a new record rather than importing the old one, so the old export is your evidence for consents given before the switch.
