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.
