Browserbase — Technical Overview
Browserbase is a cloud browser infrastructure platform purpose-built for AI agents and automated workflows. It exposes a fully programmable, scalable fleet of browser sessions via API, making the web as reliable and composable as a REST endpoint.
Key technical characteristics:
- API-first cloud browsers: Spin up, control, and tear down remote browser sessions programmatically at scale — 35M+ sessions/month across 250+ concurrent browsers at the Scale tier.
- Model-agnostic: Integrates with any LLM or agent framework via a Model Gateway, with no lock-in to a specific model provider.
- Open-source Stagehand framework: A first-party, open-source browser automation framework (25,785+ GitHub stars) designed for agent-driven web interaction.
- Anti-bot & Agent Identity: Built-in CAPTCHA bypass and agent identity management to handle modern bot-detection systems without custom engineering.
- Search & Fetch APIs: Token-efficient APIs for retrieving structured web context — ideal for RAG pipelines and agent memory without full browser overhead.
- Observability: Session replay, live view, and logging baked into the platform for debugging and monitoring agent runs.
- Integrations: Native support for Cloudflare, Stagehand, and MCP (Model Context Protocol).
- Compliance: SOC-2 Type II certified infrastructure.
- Open source: Yes | API available: Yes | Founded: 2024
