What is webchanges-docker?

This project packages a tool called webchanges into a lightweight container so you can run it without dealing with Python installations or dependencies. Webchanges itself monitors websites for updates and notifies you when something changes, useful for tracking price drops, news pages, product availability, or any page where you want to know the moment content shifts. Instead of installing Python, managing packages, and configuring a scheduler on your machine, you provide two configuration files: one listing the URLs to watch and another specifying how you want to be notified (email is one option). The container handles the rest, checking your listed sites every 15 minutes by default and sending you an alert when a page changes. You can adjust that checking interval if you want it to run more or less frequently. The people who would use this are typically running webchanges already or want to start, but prefer not to maintain a Python environment on their server. For example, if you track a vendor's changelog for security patches or monitor a competitor's pricing page, this lets you set that up once and let it run in the background with automatic restarts. It also includes a testing mode so you can verify that your page-tracking rules work correctly before relying on them. The project is notable for keeping the image small at around 35 MB, built on Alpine Linux, and it bundles several optional webchanges features like advanced HTML parsing, database import from the older urlwatch tool, and notification through Pushover. The version number mirrors the underlying webchanges release, so you can tell at a glance which features you are getting. The README doesn't go into detail on advanced configuration beyond pointing to the official webchanges documentation.
