Swetrix CAPTCHA: sovereignty score and 8 European alternatives

Swetrix CAPTCHA is an open-source CAPTCHA from Swetrix Ltd that blocks bots and spam without cookies or user tracking. It uses an invisible proof-of-work challenge that checks the visitor's device in the background. You create a CAPTCHA project in the Swetrix dashboard, add the widget snippet to your forms and verify responses through the API on your own server. Colours and theme can be adjusted. The service is included in Swetrix Analytics plans and can also be self-hosted.

Swetrix Ltd is registered in Edinburgh, Scotland, and is therefore subject to United Kingdom law. The company describes the product as made in the UK and Ukraine and hosted in the EU; its privacy policy names Hetzner Online GmbH in Germany as hosting provider. The widget code is published under the MIT licence. For European organisations, this means EU hosting by a provider based outside the EU, with the option of running the CAPTCHA on their own infrastructure.

Why digital sovereignty matters with Swetrix CAPTCHA

Swetrix CAPTCHA is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Data is hosted exclusively in the EU, so Swetrix CAPTCHA scores best on data residency.

Swetrix CAPTCHA is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Swetrix CAPTCHA together with your other vendors and gives a total score, a heatmap and the main risk drivers.
