Meerkat is an open-source, webhook-native API for async agent tasks. Run background work similar to Sidekiq — register a job and walk away — but describe the task in plain English and Meerkat understands what to do and acts accordingly (fetch pages, extract data, compare state, retry on failure). Monitor any website for changes, track shipments, watch competitor prices and stock, or schedule recurring scraping jobs — and get an HMAC-signed webhook when something happens. Bring your own LLM key (OpenAI, Anthropic, OpenRouter, Grok, or open-source models via compatible providers) — no schedulers or webhook plumbing to build yourself.
