E2B
Firecracker sandboxes for untrusted agent code
AI Agents / Orchestration · Freemium
What's Good
When your agent writes code, where does it run? E2B provides Firecracker-based sandboxes—lightweight VMs that spin up in milliseconds, execute untrusted code, and tear down cleanly. The infrastructure lets agents be dangerous without risking your systems. SDKs for Python and TypeScript.
The Catch
Hosted by default. You are sending code to E2B infrastructure. Self-hosting is possible but requires more work. Another external dependency in your agent stack.
Verdict
Safe sandboxes for agent-generated code. Hosted convenience.
