How do I run changedetection.io with Docker?
Run the ghcr.io/dgtlmoon/changedetection.io image with a volume mounted at /datastore and port 5000 published, then open it in a browser. The project's docker-compose.yml does the same.
ChangeDetection: Website Change Monitor
Run website change detection on your own server. Add a page, pick the part to watch, and changedetection.io alerts you when its text changes, the price drops or the item is back in stock. Alerts go out by email, Discord or a webhook, and more services are supported.

Common questions
Can changedetection.io monitor pages that need JavaScript?
Yes, with a Playwright or WebDriver content fetcher, which runs a real Chrome. The default fast fetcher does not run JavaScript.
Does changedetection.io track prices and restocks?
Yes. Turn on the re-stock and price detection option for a single product page, then set an upper or lower price, or a percentage change, to alert on.
