ConfigCat: sovereignty score and 8 European alternatives

ConfigCat is a hosted feature flag and configuration management service. Teams can switch features on or off from a dashboard without redeploying, target audiences by attributes such as region or email address, run percentage rollouts and A/B tests, and manage text and number values alongside boolean flags. It offers audit logs, webhooks, a management API, SSO and integrations with Jira, Slack and GitHub, among others. The SDKs for many platforms are open source under the MIT licence and keep working without an internet connection. For self-managed use, the vendor also mentions an on-premise option.

ConfigCat Kft. is based in Budapest, Hungary. Configuration files are distributed through the Cloudflare network. You choose between Global, the default, and EU Only, where according to the vendor the files are published only to EU CDN nodes. The vendor states that user data is evaluated client-side and stays in your own system.

Why digital sovereignty matters with ConfigCat

ConfigCat is headquartered in HU and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

ConfigCat hosts data in EU, US, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

ConfigCat 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 ConfigCat together with your other vendors and gives a total score, a heatmap and the main risk drivers.
