Browserbase solves the unglamorous but critical infrastructure problem behind any AI agent that needs to browse the web: running headless browsers reliably at scale without getting blocked. It handles stealth fingerprinting so automated sessions don't look obviously automated, rotates residential proxies, solves CAPTCHAs automatically, and records sessions for debugging when an agent does something unexpected.
Agents can drive a Browserbase session through standard tools like Playwright, Puppeteer, or Selenium, or through Stagehand, Browserbase's own framework built specifically for AI-driven browser control rather than traditional scripted automation. That flexibility means it can slot into an existing automation codebase rather than forcing a rewrite around a proprietary API.
The company reports 36.9 million browser sessions as of March 2026, a figure that reflects how much of the current wave of browser-use agents, from research tools to shopping assistants, runs on top of infrastructure like this rather than building their own browser farm from scratch.
