ChangeDetection: Page change monitoring with alerts
ChangeDetection is a self-hosted monitoring tool. Page change monitoring with alerts.
Why self-host ChangeDetection
When you deploy ChangeDetection yourself, you own the instance. That means no rate limits, no pricing changes, and no worry about the service shutting down.
What it does
ChangeDetection falls into the Monitoring category of self-hosted software. It is designed to be deployed on your own infrastructure, whether that is a home server, a VPS, or a local machine running Docker.
Community traction
The project has 16k stars on GitHub, which is a reasonable proxy for how widely it is used. Active repositories tend to ship bug fixes faster and have better documentation than projects that stall after the initial release.
Deployment
Docker is the most common deployment path. If you are already running containers at home, adding ChangeDetection to a compose file is a low-friction way to try it.
Maturity
The current version is 0.46.02, which means the project is still pre-1.0. That is not a disqualifier, but it is worth checking the changelog before upgrading in a setup where stability matters.
License
It is licensed under Apache-2.0, making it freely available for personal and commercial use.
Links
For anyone already running a home server, ChangeDetection is a natural addition. It handles monitoring without requiring a paid subscription or an account with a third party.
