Supacrawler is open source web scraping api built in Go for performance and concurrency. Playwright-Go for JS rendering, Redis for caching and queuing. Also easy to self-host (clone + docker-compose) or use hosted version.

What Supacrawler supports:

- v1/scrape — fetch content (HTML, js rendered) from a URL

- v1/crawl — follow links to crawl entire sites or sections

- v1/screenshots — capture visual renderings of pages (full page, element, etc.)

- v1/watch — monitor pages for changes over time

- v1/parse — the new endpoint: you submit a URL + a schema or desired format (JSON, CSV, YAML, Markdown), and it returns structured data without needing custom scraper logic
