These platforms handle the complexity of browser lifecycle management, anti-detection, session persistence, and scaling. They're critical for AI agents that need to interact with authenticated websites, fill forms, or navigate complex multi-step web workflows.

Editorial assessment

Strong stealth performance — scored 67% in Browser Use's independent benchmark against 71 high-security sites, beating Browserbase (42%) and Steel (47%). The $22M raise and Vercel partnership signal serious backing. Open-source browser image (Kerneloss) is a differentiator. Blog content shows technical depth in VLM training and GPU acceleration for browsers.

Steel.dev

Steel.dev is also open-source with strong stealth capabilities but focuses more on session persistence.

Anchor Browser
