Browserbase

Browserbase provides cloud-hosted headless browser infrastructure that lets AI agents and applications reliably browse, automate, and extract data from the web at scale.

Browserbase is a cloud platform that runs managed, serverless headless browsers purpose-built for AI agents and automation workloads. It removes the need to operate your own fleet of browsers, offering features such as autoscaling concurrent sessions, stealth mode, automatic CAPTCHA solving, residential proxies, live session views, and session recording/replays for debugging. Developers connect over an API and SDKs (or via the open-source Stagehand framework and a Model Context Protocol server) to have agents authenticate, navigate dynamic sites, fill forms, and interact with web apps that lack APIs. The company also ships Stagehand (an AI browser automation framework) and Director (a no-code tool that turns plain-English instructions into browser workflows). Founded in 2024 by Paul Klein IV and headquartered in San Francisco, Browserbase serves AI companies including Perplexity, Vercel, and 11x.

• ✓
  Managed headless browsers

  Serverless, autoscaling cloud browser sessions for AI agents, with concurrency limits that scale from a few sessions on the free tier to 250+ on enterprise plans.

• ✓
  Stealth mode & CAPTCHA solving

  Anti-bot stealth capabilities plus automatic CAPTCHA solving so agents can access sites that would otherwise block automated browsers.

• ✓
  Residential proxies

  Built-in proxy bandwidth (metered per GB) that lets agents route traffic to avoid geo and IP-based blocking.

• ✓
  Session recording & observability

  Live session views, logs, and replays for debugging agent runs across prompts and browser interactions.

• ✓
  Stagehand automation framework

  Open-source (MIT) SDK for AI browser automation, letting developers drive browsers with natural language and code that adapts to site changes.

• ✓
  Director no-code automation

  Tool that converts plain-English instructions into executable browser workflows for non-programmers.

• •
  AI web agents

  Give autonomous agents a real browser to complete multi-step tasks like booking, form-filling, and account actions on live websites.

• •
  Web data extraction

  Scrape and convert web pages into structured data (HTML, JSON, markdown) at scale, including sites protected by anti-bot measures.

• •
  Workflow automation for API-less sites

  Automate interactions with web applications that don't expose APIs, such as portals, dashboards, and legacy systems.

Subscription tiers include monthly browser-hour, proxy, and API allowances with usage-based overages (e.g., $0.10-$0.12 per browser hour, ~$10-$12 per proxy GB, $7 per 1,000 Search calls). Scale/enterprise pricing is custom via sales.
