Overview

REST API and UI on port 3000 that launches Chrome sessions with persisted cookies and storage, proxy chains, stealth plugins and request logging, then hands you a CDP endpoint for Puppeteer or Playwright or a WebDriver endpoint for Selenium. Quick-action endpoints return a page as HTML, markdown, screenshot or PDF. Runs from a prebuilt ghcr.io image or docker compose; Node and Python SDKs target cloud or self-hosted instances.

Who it is for: Developers building web agents on Puppeteer, Playwright or Selenium

Strengths

  • One image serves API, UI and console debugger (ports 3000 and 9223)
  • Session API persists cookies and storage; Selenium sessions via isSelenium
  • Swagger UI at /documentation on the local instance
  • Node and Python SDKs switch between cloud and self-host with baseURL

Weaknesses

  • Public beta; API still changing
  • Runs full Chrome; needs a Chrome executable when run outside Docker
  • Selenium integration lacks some features of the CDP session API
  • Apple Silicon compose needs DOCKER_DEFAULT_PLATFORM=linux/arm64

What it needs

  • no GPU
  • Docker + Compose
  • Needs Google Chrome (non-Docker runs), Node.js (non-Docker runs)
  • port 3000
