E2B
Open-source cloud sandboxes where AI agents run code, browse and use tools in isolated microVMs.
Overview
E2B is sandbox infrastructure for AI agents. It provides isolated cloud sandboxes, built on microVMs, where agents run code, browse and use tools. Teams bring their own model, prompts and agent logic. Every sandbox includes an MCP gateway with 200+ servers from Docker’s MCP Catalog. Fragments is a separate open-source prompt-to-app demo built on E2B.
The sandbox infrastructure and SDKs are open source under Apache-2.0 and can be self-hosted. E2B Cloud runs in the US, EU and APAC, and bring-your-own-cloud is available on AWS and GCP. Plans include Hobby with a one-time $100 usage credit, Pro at $150 a month plus per-second usage, and custom Enterprise with a $3,000 monthly minimum.
