Browserbase vs E2B
A side-by-side comparison of capabilities, autonomy, integrations, and pricing to help you choose.
Short answer: choose Browserbase if you want headless browser infrastructure that gives ai agents reliable web access (Supervised agent, usage); choose E2B if you want secure cloud sandboxes for running ai-generated and agent code (Supervised agent, usage).

Browserbase
- +Removes the operational burden of running and scaling real browser fleets (concurrency, proxies, auth, CAPTCHA)
- +Ships a popular open-source framework (Stagehand) and is model-agnostic, reducing LLM-layer lock-in
- +Spans the full stack from raw infrastructure to no-code agent building (Director) with MCP support
- -Browser automation against changing, anti-bot, or CAPTCHA-protected sites is inherently brittle
- -Usage-based pricing (browser hours, search/fetch calls, proxy data) can make costs hard to predict at scale
E2B
- +Fast, secure isolated execution purpose-built for AI agents
- +Open-source SDK and self-hostable runtime, with a managed cloud option
- +Model-agnostic: runs whatever code any model produces
- -Infrastructure only; you bring the agent logic and orchestration
- -Hosted usage costs scale with sandbox runtime
Which should you choose?
Browserbase is headless browser infrastructure that gives ai agents reliable web access, best for developers, smb, mid-market, enterprise. E2B is secure cloud sandboxes for running ai-generated and agent code, best for developers, enterprise. The right choice depends on the autonomy level you want, your existing integrations, and your budget, all compared above.
