Notion Watch is a free Chrome browser extension developed by Matt Daneshvar. It falls under the Browsers category, specifically as an Add-ons & Tools subcategory. This extension addresses the limitation of Notion's lack of webhook support by adding a watcher to Notion in your web browser.

By installing Notion Watch, you can set up an endpoint to receive pings each time a change is detected on a Notion page. Additionally, a Sync button is included in the Notion top bar, giving you the option to manually trigger pings or disable the watcher if preferred. Notion Watch is an open-source project, allowing users to customize and enhance features or adapt it for other browsers.
