Tolgee: sovereignty score and 8 European alternatives

Tolgee is an open-source localisation platform aimed at developers. Its central idea is in-context editing: texts can be changed directly in the running app, including by colleagues or clients. It also offers AI translation that uses context from the interface, translation memory, machine translation through providers such as DeepL, Google Translate, AWS Translate and Azure Translator, and an MCP server that lets AI coding assistants manage translations. Tolgee is available as a hosted service and as a Docker image for self-hosting.

The vendor is Tolgee s.r.o. in Brno, Czechia, so in the EU. The source code is on GitHub; the repository shows both Apache 2.0 and the Tolgee licence for enterprise features. According to its privacy policy, its servers are located in Germany, Czechia and the United States. By self-hosting, you keep data and keys entirely under your own control, without depending on an external provider.

Why digital sovereignty matters with Tolgee

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

Tolgee hosts data in EU, US. 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.

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