E2B provides secure cloud sandboxes that let AI agents execute code, run terminal commands, and interact with filesystems in isolated environments. Each sandbox spins up in ~150ms with its own OS, giving agents a safe space to run untrusted code. Supports Python, JavaScript, and any language via custom Dockerfiles. Used by AI coding assistants, data analysis agents, and code interpreters. SDK available for Python and JavaScript with a simple API for programmatic sandbox control.

Free (Hobby) tier includes $100 free usage credit, 1-hour max sandbox runtime, and 20 concurrent sandboxes. Pro tier ($150/mo + compute) extends sandbox lifetime to 24 hours, 100+ concurrent sandboxes, and custom Docker templates. Pay-as-you-go compute is billed per-second at ~$0.0504/vCPU-hr and ~$0.0162/GB RAM-hr. Enterprise tier offers dedicated microVM clusters, VPC peering, SOC 2 Type II compliance, and 99.9% SLA with custom commitments.Review →
