E2B provides sandboxed cloud environments for AI-generated code execution. Micro-VMs that spin up in 150ms for safe code execution by AI agents.
Reviewer scorecard
“The free tier is absurdly generous and the cold starts are essentially zero. For APIs, middleware, and edge logic, nothing else gives you this performance at this price.”
“150ms cold starts for sandboxed code execution. Essential for AI agents that need to run untrusted code safely.”
“The Worker runtime has limitations — no Node.js stdlib, size limits, CPU time limits. Know the constraints. But for what it does well, it's unbeatable.”
“AI agents running code need sandboxing. E2B's micro-VMs are purpose-built for this use case.”
“Cloudflare is building the programmable internet. Workers + D1 + R2 + AI = a complete platform that runs at the edge. They're quietly becoming the default infrastructure layer.”
“Safe code execution for AI agents is critical infrastructure. E2B is building the sandbox layer that every agent needs.”
