Site Spy

About

Site Spy provides automatic website change monitoring. Using either a browser extension for Chrome and Firefox or the web dashboard, you can add any page and receive immediate notifications when content is modified. Visual differences are shown clearly, with additions highlighted in green and removals in red. The element inspector enables tracking of particular items, such as prices or headlines. Features include color-coded tags, snapshot timelines, and MCP server integration for AI assistants. A free plan is available, and no credit card is required.
