Cloud browser infrastructure provides managed Chromium instances that AI agents can control remotely. 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

The category leader – $300M valuation, 50M+ sessions, and the Stagehand SDK is genuinely excellent for building agent workflows. Perplexity and Vercel as customers is strong social proof. Premium pricing reflects the enterprise positioning. The Stagehand SDK creates some lock-in. But for serious agent infrastructure, Browserbase is the benchmark everyone else is measured against.
