Use case · Website monitoring

Watch any URL. Get a webhook when the thing you care about changes.

A website change detection API that understands intent. Instead of raw diffs, you describe the signal — a price drop, a stock flip, a competitor's pricing page edit — and Meerkat's agent watches on a schedule. It only fires your webhook when the described change actually happens.

Semantic, not pixel diff

Plain-English conditions like 'price under $99' or 'plan name changed'. No selectors to maintain.

JS-rendered pages

Headless browser rendering means SPAs, React, and dynamic content work out of the box.

Schedule it your way

Cron strings, natural language ('every 15 minutes'), or on-demand POST /tasks/:id/run.

Self-host or Cloud

Same REST API. Run it on Docker, Fly.io, Render — or use Meerkat Cloud with BYOK.

FAQ

Common questions

What kinds of changes can it detect?

Anything an LLM agent can see — price drops, stock status, copy edits, new blog posts, regulatory text updates, competitor pricing pages. You describe the signal in English; Meerkat watches for it.

How is this different from diff-based monitors?

Raw-diff tools fire on every cosmetic change. Meerkat understands semantic intent — 'tell me when the price drops below $99' — and only POSTs when that condition is met.

Can it follow JavaScript-rendered pages?

Yes. The agent renders pages in a headless browser before reasoning, so React, Vue, and SPA-rendered content work the same as static HTML.

What about rate limits and politeness?

Meerkat respects robots.txt, throttles per-domain, and reuses cached fetches across tasks targeting the same URL.
