pgvector runs on your own machine — the client starts it, so there is no endpoint to ping. 88 installs a week from pypi. Last commit 21 Jul 2026.

Nothing serious here today
Today is the operative word: we check pgvector every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
