Chronoverify runs on your own machine — the client starts it, so there is no endpoint to ping. 74 installs a week from npm. Last commit 31 Aug 2026.
Verify a photo's capture time and provenance: C2PA validation, EXIF/XMP, and pixel forensics.
Today is the operative word: we check Chronoverify every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
