About E2B
E2B (Execute to Build) provides cloud sandboxes for running AI-generated code safely. When you build an AI application that executes code - a coding assistant, a data analysis agent, or an autonomous programmer - you need a secure environment where that code can run without risk to your production infrastructure. E2B provides that infrastructure as a service, offering isolated virtual machines that spin up in milliseconds and are designed specifically for AI workloads. Developers building AI coding tools, autonomous agents, or data science applications use E2B to handle the execution layer. Instead of building and maintaining sandboxed environments from scratch, teams integrate E2B's SDK and get managed, scalable execution infrastructure. The sandboxes support multiple programming languages, have internet access when needed, and can be customised with dependencies pre-installed. E2B is a developer-first product used primarily by teams building AI-native applications. It has become a standard component in AI agent architectures where code execution is required. The free tier covers development and prototyping; production workloads move to usage-based pricing.
