Build smarter AI agents with secure Cloud Sandboxes
Learn how to build production-ready agents with hands-on guides, deep technical breakdowns, and real-world case studies.
Sandboxes are dead
From code snippets to entire computers, agents have outgrown the sandbox. E2B's next chapter is an agent-driven private cloud that adapts to every task.
Best Code Execution Sandboxes for AI Agents in 2026
Compare the best 2026 code execution sandboxes for AI agents. See how E2B stacks up against alternatives for isolation, BYOC, billing, and open source.
Introducing E2B Secrets
E2B Secrets keeps credentials outside the sandbox and injects them into the HTTPS request headers you configure, so agents can call external services safely.
How I Learned to Stop Worrying and Love the Sandbox
A hands-on lab in running sandboxes: runaway processes, memory pressure, full disks, idle timeouts and per-user workspaces.
Introducing E2B Embed
E2B Embed packages the runtime and dashboard for one machine. Ship it with your product and run sandboxes inside your customer's environment.
Build an Agent Workbench on OpenAI's Agents API
A workbench built on OpenAI's Agents API (beta) and E2B sandboxes: application-managed lifecycle, one sandbox per chat, pause and fork.
Use E2B as the Execution Layer For Devin Outposts
Devin Outposts lets you run Devin sessions inside infrastructure you control, with each session running on an E2B microVM that keeps execution entirely within your cloud boundary.
E2B sandboxes are now available through Stripe Projects
AI agents can now provision and authenticate E2B sandboxes directly through Stripe Projects.
E2B Sandboxes Aren't Affected by Copy Fail (CVE-2026-31431). Here's why.
Containers fail where purpose-built AI computers shine.
E2B is now supported in the OpenAI Agents SDK
Building long-horizon agents just got easier.
