In March 2023, Grafana Labs acquired Pyroscope, the company behind the eponymous open source continuous profiling project. In September 2023, Grafana Pyroscope v1.0.0 was released.

This documentation covers Pyroscope versions preceding v1.0.0. We're keeping it for the time being, but we recommend that you upgrade to Grafana Pyroscope v1.0.0 or higher and switch to the new Grafana Pyroscope Docs for most up-to-date documentation.
