Perses is an open-source dashboard specification and tool for observability data, with a focus on Prometheus metrics; it also supports Tempo traces, Loki logs and Pyroscope profiles. Dashboards are written as code using its software development kits and can be validated and deployed from continuous integration pipelines with a command-line tool. The organisation installs and operates the software itself.
Perses is a sandbox project of the Cloud Native Computing Foundation, which is part of the Linux Foundation, and it is released under the Apache 2.0 licence. Governance therefore sits with a US-based foundation rather than with a single company. For a European organisation, the open licence makes self-hosting possible without any data transfer to the project, although the foundation's jurisdiction remains a point to consider.
