Core capabilities available via API:
- Launch and manage concurrent remote browser sessions
- Search & Fetch API calls for token-efficient, structured web data retrieval
- Agent Identity and CAPTCHA/anti-bot bypass
- Session replay and live view for observability and debugging
Integrations:
- Stagehand — Browserbase's own open-source browser automation framework, optimized for AI agent workflows (25,785+ GitHub stars)
- Cloudflare — Infrastructure-level integration
- MCP (Model Context Protocol) — Enables standardized agent-to-tool communication
