Webdog.ai watches any website and tells you the moment it changes; new links, removed links, content edits, or price drops. Every check is powered by Context.dev's web APIs: clean markdown scraping, product & price extraction, live page screenshots, and AI-written summaries that explain what changed and why it matters. Add a monitor in seconds (just paste a URL), get alerts via Slack, email, or webhooks, and share a read-only page. Open-source, self-hostable, PostgreSQL-backed.

Hey Product Hunt 👋 We built Webdog.ai because I wanted a simple, inspectable way to watch websites for meaningful changes, not just text diffs, but new links, removed links, and content updates. A lot of website monitoring tools are closed SaaS products. Webdog.ai is different: it’s open-source, self-hostable, and backed by PostgreSQL, so you can run it yourself, keep your data, and extend it for your own workflows. It’s useful for tracking competitor pages, documentation, directories, changelogs, pricing pages, and any site where changes matter. I’d love feedback from the PH community, especially around what kinds of website changes you’d want to monitor next.

Love the simplicity of just pasting a URL and getting diffs. One thing that would save me a ton of time is a per-page "ignore" rules option, like skipping changes inside a specific CSS selector or regex (e.g. ignore timestamps, cookie banners, "people also viewed" carousels). Would cut down on noisy alerts a lot.
