Sidecrew runs on your own machine — the client starts it, so there is no endpoint to ping. 124 installs a week from npm. Last commit 22 Sep 2026.
Code changes and unit tests by local MLX models, behind a gate a machine can run.
Nothing serious here today
Today is the operative word: we check Sidecrew every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
