A self-hosted web application for monitoring websites and detecting content changes, with alerts via Discord, Slack, Telegram, email, webhooks and 85+ other channels. It supports element targeting, browser-based interactions, restock/price tracking, and optional AI-powered change summaries and filtering via any LLM provider.

Use cases

• monitor a product page for price drops
• get notified when an out-of-stock item is back in stock
• track changes to a government or documentation webpage
• watch a webpage and only alert on specific HTML elements
• detect website defacement
• get a plain-language summary of what changed on a page
• monitor login-protected pages with browser steps

When to choose

• you want a free, self-hosted alternative to paid website watchers like Visualping or Distill
• you need flexible notification integrations (Discord, Telegram, Slack, email, webhooks)
• you want to track price changes, restocks, or content edits on specific pages
• you need to monitor pages behind logins or with interactive browser steps

When to avoid

• you need large-scale distributed web crawling or scraping pipelines rather than per-URL change watching
• you want a fully managed SaaS without self-hosting and don't want to pay for the hosted plan
• you need real-time streaming monitoring with sub-second latency
