Know when a changelog or docs page changes
Paste a changelog, release notes or documentation page into ChangePing. When it changes, you get a two or three line summary of what was added or removed, by email, in Slack or Discord, or as a signed webhook to your own code.
It's useful for tools that have no RSS feed, for API docs that change without notice, and for keeping a team channel informed about the products you build on.

How to set it up
- 1
Paste the changelog or docs page
Any public page, including docs sites rendered with JavaScript.
- 2
Watch the list or the whole page
Click the list of releases, or keep the whole page for docs.
- 3
Send it to your team
Connect a Slack or Discord channel, or a webhook with a signed JSON body, so nobody has to check by hand.
Tips
- If the project is on GitHub, its Releases page has an Atom feed you can use in a feed reader. ChangePing is for pages that have no feed.
- Docs pages often show "Edited 3 days ago" lines. Ignore lines containing "Edited" to skip those.
Questions
Can my code receive the change?
Yes. Add a webhook and every change is sent as JSON with the before and after lines, signed with HMAC-SHA256.
Can an AI assistant read the changes?
Yes. ChangePing has an MCP server, so Claude and ChatGPT can create monitors and read what changed for you.
