What is Browserbase?

Browserbase is a cloud platform, founded in San Francisco in 2024, that provides managed headless-browser infrastructure for loading, rendering, and extracting data from live websites. It has a Sessions API for spinning up cloud browsers, a Search API, and a Fetch API that converts URLs into HTML, JSON, or markdown, plus session recording, observability and debugging tools, and proxy/stealth/CAPTCHA handling. The company also builds and open-sources Stagehand, an AI browser-automation SDK, and ships Director, a no-code natural-language automation tool.

Our verdict

Browserbase fits teams building AI agents that need managed, scalable browser infrastructure without running their own headless-browser fleet, and it has disclosed funding of roughly $67.5M, including a $40M Series B. It is a hosted service, not open-source or self-hostable, so teams that want full infrastructure control or on-premises deployment will need a different tool.

Browser Infrastructure

Browser infrastructure gives you a remote Chrome or Chromium instance over a protocol like CDP or Playwright, so you run automation without managing browser servers. It is the layer many scraping APIs and agent tools build on, and it suits teams that want control of the browser without the operations work.

How Browserbase compares

Browserless

Browserless is a long-established headless Chrome hosting service that competes directly with Browserbase's Sessions API for running browsers in the cloud.

Steel

Steel is an open-source browser infrastructure project that gives teams a self-hostable option, while Browserbase has only a managed service.

Hyperbrowser

Hyperbrowser is another cloud browser platform built for AI agent workflows, and it overlaps with Browserbase's agent-focused Sessions and Fetch APIs.
