Hosting changedetection.io

changedetection.io watches web pages and sends notifications when selected content changes. It can monitor simple HTTP responses or use a browser-based fetcher for pages that need JavaScript.

Use the resource planner to size a server for your workload.

Choosing a server for changedetection.io

Browser-based checks generally do more work than fetching plain HTTP content. Page count, scheduling, retained history and concurrent fetches determine the deployment workload.

Deploy with

Supported paths

Docker Compose
Docker container
Python package installation

The host must provide

Runtime

Page fetcher: Built-in HTTP fetcher; optional browser-based fetching for JavaScript pages

Storage

Persistent data

Persist /datastore to retain watches and saved state. History and captured content can grow with the number of monitored pages and their check frequency.

Step by step

Plan a changedetection.io deployment

Persist the watch data

Map the datastore to durable storage before creating watches. Use the maintained image and retain the same data when updating it.
Official instructions
Select the fetch method

Use the HTTP fetcher where it handles the page; configure the browser-based option for content requiring JavaScript.
Official instructions
Tune alerts

Choose the relevant page elements and notification rules so routine navigation or footer changes do not overwhelm the intended alert.
Official instructions

Security

Before you go public

Protect access to the monitoring interface and saved login sessions.
Keep notification tokens private and respect the monitored site’s access rules.

Cost

Beyond the server price

Include browser processing and saved history in the hosting budget.
Optional proxies, notifications and model services can have separate charges.
