Browserbase

Managed headless-browser infrastructure for AI agents at scale.

About

Browserbase is managed headless-Chromium infrastructure: instead of provisioning your own browser fleet, you request a browser from the API and get a real sandboxed cloud session with stealth/anti-bot handling, residential proxies, CAPTCHA solving, session recording, and a live view. You drive it with standard Playwright or Puppeteer over CDP.

It is the commercial counterpart to Stagehand, the company's open-source MIT browser-automation framework with natural-language act/extract/observe primitives — Stagehand runs locally for free or points at Browserbase cloud for production scale.

Pricing: free tier (1 browser hour, 3 concurrent), Developer $20/mo (100 hours), Startup $99/mo (500 hours, 100 concurrent). Honest limits: it is proprietary infrastructure with vendor lock-in, and costs scale with browser-hours at serious volume.

What it can do

  • On-demand cloud Chromium sessions
  • Stealth and anti-bot handling
  • CAPTCHA solving included
  • Residential proxies and session recording
  • Live session view
  • Stagehand OSS framework (MIT)

Setup

  1. Sign up at browserbase.com and create a project + API key.
  2. Create a session: POST https://api.browserbase.com/v1/sessions.
  3. Connect with Playwright: chromium.connectOverCDP(session.connectUrl).
  4. Or use Stagehand: npx stagehand init, then point it at your Browserbase key.

Prerequisites

Browserbase account and API key; Playwright or Puppeteer (or Stagehand).
