Kate: sovereignty score and 8 European alternatives

Kate is a fast text editor from KDE in which several documents and views can be open at once. The program supports LSP, git integration and a built-in terminal, and runs on Linux, BSD, Windows and macOS. Kate is aimed primarily at programmers. It is a desktop application that runs locally on the user's device; there is no vendor cloud service. The source code is available under the LGPL-2.1 or later.

Kate is developed by the KDE community. Legal and financial matters are handled by KDE e.V., a registered non-profit association with its seat in Berlin, Germany. The KDE privacy policy, which covers all KDE software, states that software does not transmit information from the user's device except as a result of an explicit user action, and that telemetry is opt-in and disabled by default. The policy does not mention the GDPR by name. For a European organisation this is open-source software from a German non-profit that does not depend on a foreign cloud provider, although modified versions from third-party distributors may differ.

Why digital sovereignty matters with Kate

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

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

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