Browserbase

Browserbase is an agent-focused headless-browser company that has positioned itself as infrastructure for the AI-agent era. In 2025 it raised a $40 million Series B at a $300 million valuation, per a 十字路口Crossing report from that August . The company is building what it calls a "browser-native" AI development platform—developers open a web page and use embedded model assistants for code generation, debugging and collaboration, without installing a local environment . More recently, in May 2026, the same outlet noted Browserbase had launched browse.sh, a browser designed specifically for agents to acquire capabilities, framing the company as a concrete example of the "distribution layer" for agent infrastructure . Elsewhere's corpus does not cover the subject in depth beyond these two mentions.
