About

Klaxon Cloud is a tool for journalists, researchers and civic creators to track changes to pages across the web. Powered by the Wayback Machine, Klaxon will monitor web pages for changes, notifying you when something's changed.

With the Klaxon Cloud browser extension, you can:
- Create new alerts, optionally highlighting an area of the page to watch.
- See all alerts you've created for a website, then quickly jump to a page you're watching.
- Manage alerts you've created, with the ability to edit or disable them.

A free MuckRock Account is required for saving your alerts.

Klaxon Cloud is a project of the MuckRock Foundation: a nonprofit, collaborative organization and newsroom that brings together journalists, researchers and the public to request, analyze and share government information, making politics more transparent and democracy more informed.
