changedetection.io watches any web page and alerts you the moment it changes, with a visual diff of exactly what was added or removed, preinstalled and running behind nginx and ready within minutes of launch. A unique access password is generated on first boot. Backed by 24/7 cloudimg support.
## changedetection.io by cloudimg
Self-hosted website change monitor: point it at any URL (optionally a CSS/xpath region), it re-fetches on a schedule, stores snapshots and shows a clear visual diff of what changed. Delivered fully installed behind an nginx reverse proxy - a change-monitoring console serving within minutes. Current release changedetection.io 0.55.7. Runs as a container on loopback fronted by nginx :80 with the WebSocket upgrade its live watch list needs; settings, history and diffs on a dedicated independently resizable data disk. First boot generates a per-instance access password, applies it with the application's own salted hash, verifies the sign-in round-trip and records it in a root-only file - no shared or default credentials ship, and the password can be changed or removed from Settings. Notify via email, webhooks, Slack, Discord, Telegram and more; group with tags; monitor price/stock changes. 24/7 cloudimg support.
