Headless Browser

Chromium-based browser sessions for screenshots, scraping, and agentic web use.

Headless Browser sandboxes

A real Chromium session, tenant-isolated, with a Playwright-compatible API and a browser-use-compatible harness for agentic navigation. Sessions can be kept warm with cookies and storage state, or torn down per call.

Two access shapes

  • API: Request a screenshot, PDF, scrape, or rendered-HTML dump in a single HTTP call. Best when your agent doesn’t need step-by-step control.
  • WebSocket session: Drive Chromium directly with Playwright (or a harness like browser-use). Best when the agent’s loop wants to react to what it sees.

Egress posture

  • Default egress: datacenter-IPs, suitable for public-web reads where rate-limit avoidance doesn’t matter
  • Residential-egress: opt-in, billed separately, capped per session to avoid abuse — request via support before founding

We do not currently offer “human-in-the-loop CAPTCHA solving”; if your workflow depends on that, talk to us about a tenant-specific contract.

Limits

  • 30 minute wall-clock per session by default
  • 250 Mbps egress, capped at 10 GB / session
  • 2 GB RAM default; raise to 6 GB on per-session upgrade

What we don’t allow

  • Logged-in scraping where the auth credential isn’t yours
  • Anything that knowingly violates a target site’s ToS — we will pull the plug on tenants that turn the platform into a complaints magnet

Best for

  • Agents that need to read JavaScript-rendered pages
  • Screenshot / PDF / archive workflows
  • Full-site scraping with login state
  • Agentic browser use (book, fill, search, navigate)
