Memharness runs on your own machine — the client starts it, so there is no endpoint to ping. 45 installs a week from npm. Last commit 26 Jun 2026.
Bi-temporal, provenance-carrying long-term memory for AI agents, in one SQLite file.
Today is the operative word: we check Memharness every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
