About this plugin
CodSpeed gives Claude performance context from benchmark results, flamegraphs and comparisons, helping identify bottlenecks and iterate on code changes. It can work with existing benchmark suites or executable programs across languages including Python, Rust, Node.js, Go and C/C++.
Use it when investigating slow code, setting up a benchmark harness or checking for performance regressions. The CodSpeed CLI must be installed and authenticated with a CodSpeed account; it officially supports Ubuntu 20.04, 22.04, 24.04 and Debian 11 or 12.
