Browserbase is a developer-focused infrastructure company that provides a cloud-hosted platform for building and deploying AI agents capable of browsing and interacting with the web like humans. The platform supplies the browser automation primitives - headless browsers, proxies, CAPTCHA solving, and session management - that AI agents need to programmatically navigate websites, extract data, fill out forms, and interact with web applications lacking APIs. It scales to thousands of concurrent browser sessions and serves thousands of companies.
The company's product suite includes cloud-hosted browser infrastructure, Search and Fetch APIs for fast context retrieval, runtime sandboxes for agent code execution, Agent Identity for handling web authentication, and a Model Gateway for accessing major AI models. Browserbase also maintains Stagehand, an open-source framework that has reached approximately 2 million monthly downloads and around 17,000 GitHub stars.
Browserbase operates in the developer tools, AI infrastructure, and automation verticals. The company raised $40 million in Series B funding.
