As answered by people managing Git X-Modules and SiteSpy.app.
SiteSpy.app's answer:
Element-level tracking lets you click on any part of a webpage to monitor just that section instead of the whole page. It also includes an MCP server so AI assistants like Claude can create watches and summarize changes directly.
SiteSpy.app's answer:
Most website monitors only track full pages. Site Spy lets you pin a specific element — a price, headline, or stock status — so you get notified about the exact change you care about, not every minor page update.
SiteSpy.app's answer:
Anyone who needs to stay on top of website changes — shoppers tracking prices, job seekers watching listings, marketers monitoring competitors, researchers following regulatory updates, and developers integrating website monitoring into AI workflows via MCP.
SiteSpy.app's answer:
Built as a side project by a solo developer who wanted a simple way to track website changes without expensive subscriptions. Started as a browser extension and grew into a full platform with a web dashboard, visual diffs, and AI integration.
SiteSpy.app's answer:
React and Vite for the browser extension, Next.js for the web dashboard, Flask for the backend, and the Model Context Protocol (MCP) SDK for AI agent integration
