Kieker: sovereignty score and 8 European alternatives

Kieker is an open-source observability framework for application performance monitoring (APM) and dynamic software analysis. It consists of a monitoring and tracing agent that records the runtime behaviour of a system, and analysis tools that process that data. Developers and operators use it to complement static code analysis with measurements from running systems. Kieker is distributed through Maven repositories; its source code is on GitHub, and the most recent stable release, version 2.0.3, dates from April 2026.

Kieker is licensed under the Apache License 2.0 and is maintained by Kiel University in Germany. It is a library and agent that runs inside an organisation's own applications, so monitoring data stays where the software is deployed. There is no vendor-hosted service or cloud, so no service contract with a provider applies. For a European organisation it is an open and inspectable option, though it requires in-house operating expertise.

Why digital sovereignty matters with Kieker

Kieker 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 Kieker scores best on data residency.

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