Readme

changedetection

changedetection.io — watch web pages for changes and get notified: price drops, restocks, content edits, and more, with visual diffs, CSS/XPath/JSON filters, and 90+ notification targets (via Apprise).

Single host-networked Nomad service with a /datastore volume.

Deploy

nomad-pack registry add nomploy https://github.com/Nomploy/nomad-packs
nomad-pack run changedetection --registry=nomploy

Configure

Variable	Default	Description
`port`	`5001`	Web UI port (`PORT`).
`base_url`	`""`	`BASE_URL` used in notification links.
`data_volume`	`changedetection_data`	`/datastore` — config + watch history.
`image`	`ghcr.io/dgtlmoon/changedetection.io:latest`	Image. Pin a tag in production.
`resources`	`{ cpu = 500, memory = 512 }`	Task resources.

Add a URL, set an interval, and you get diffs + notifications on change. Set an app password under Settings if it's reachable beyond your LAN. For JavaScript-heavy pages, run a separate Playwright/Chrome container and set PLAYWRIGHT_DRIVER_URL (plain HTTP fetching works without it). Pin the job to the node holding the volume with constraints.
