E2B

Open-source cloud sandboxes for running AI-generated code securely in Firecracker microVMs

Open Source Free Trial

E2B provides secure, isolated cloud sandboxes for executing AI-generated code. Each sandbox runs in a Firecracker microVM, starts in ~80ms, and can run up to 24 hours. Python and JavaScript/TypeScript SDKs let you start and control sandboxes programmatically. Anything that runs on Linux runs in an E2B sandbox. Common use cases include AI code interpreters, data analysis agents, and any AI agent that needs to execute code safely. The Hobby tier is free with a $100 usage credit.
