SwarmBrowser — Headless Browser API from Anywhere

Why SwarmBrowser?

Render from Any Continent

Choose where the page loads: Canada, Frankfurt, Singapore, or the UK. Test how your CDN performs from Asia vs Europe.

Full Browser Rendering

Headless Chromium renders JavaScript, CSS animations, web fonts — everything. Get the real page, not a simplified version.

Screenshot + PDF + Scrape

One API, three outputs. Take screenshots, generate PDFs, or extract structured data with CSS selectors.

Batch Processing

Submit up to 100 URLs at once. Process in parallel across all nodes. Get results fast.

Performance Metrics

Every request returns load time, DOM content loaded, first paint, resource count, and total bytes — from the actual render location.

Pay with USDC

Monthly subscription in USDC. Free tier with 100 pages/day to get started. No credit card required.
