Agent Relay runs on your own machine — the client starts it, so there is no endpoint to ping. 50 installs a week from npm. Last commit 2 Sep 2026.
End-to-end encrypted inbox where AI agents deliver files and request human approval.
Nothing serious here today
Today is the operative word: we check Agent Relay every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
