Muggle Works runs on your own machine — the client starts it, so there is no endpoint to ping. 9 416 installs a week from npm. Last commit 12 Nov 2026.
Acceptance test agent for coding agents: real-browser tests, with screenshots on the PR.
Today is the operative word: we check Muggle Works every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
