# E2B: Pricing, Features & Alternatives

E2B is the sandbox layer many agent products and code-interpreter features call when a model writes code that has to actually run. Each sandbox is an isolated microVM that starts in well under a second, with SDKs for Python and JavaScript and filesystem, process and network access. Compute is billed per second on every plan ($0.000014 per vCPU-second, $0.0000045 per GiB-second). Plans change the limits: Hobby is free with $100 of one-time credit, 1-hour sessions and 20 concurrent sandboxes. Pro is $150/month for 24-hour sessions and 100 concurrent sandboxes, with add-ons up to 1,100\. Enterprise starts at $3,000/month and adds bring-your-own-cloud.
