Gaff Check runs on your own machine — the client starts it, so there is no endpoint to ping. 56 installs a week from npm. Last commit 15 Aug 2026.
Irish property due diligence: planning, prices, flood, radon, zoning, BER and crime context.
Today is the operative word: we check Gaff Check every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
