Grounder runs on your own machine — the client starts it, so there is no endpoint to ping. 130 installs a week from pypi. Last commit 13 Aug 2026.
Web grounding for local & cloud LLMs: search, fetch, token-capped evidence packs, and research.
Nothing serious here today
Today is the operative word: we check Grounder every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
