E2B
Secure cloud sandboxes for running AI-generated code and agents. · E2B · AI
Overview
E2B gives each new account a one-time credit for sandboxes. It is a starter credit, not a monthly allowance.
Good fit
Use when you build an agent that must run untrusted code safely.
- AI agents
- code interpreters
Not a fit
Avoid if you need a lasting free allowance; the credit is one-time.
- long-running free workloads
