hotpath Diff
Work in progress. hotpath Diff is performance regression testing for Rust pull requests: it compares the report a pull request produced with the one its base branch produced, judges the difference under a per-repository policy and posts the verdict as a comment on the pull request. This page will document how to set it up; until then, the waitlist below is where to sign up for early access.
hotpath Diff - every Rust PR gets a performance review
Catch regressions in memory, SQL queries, HTTP calls and concurrency bottlenecks before they reach production. Iterate on reproducible signals, not CI noise.
hotpath Diff will also provide agents with clear performance constraints and help ensure that AI-built applications stay fast.
Launching soon • Early access invitations will be sent to waitlist members first.
