About E2B

E2B supplies cloud sandboxes where AI agents can execute code and use terminal, filesystem, and Git tools without entering the host application environment. Common uses include coding agents, deep-research workflows, computer-use agents, automations, and reinforcement-learning workloads. E2B charges by the second while a sandbox is running; billing stops when it is paused, killed, or times out. Hobby has no monthly base fee and comes with $100 in one-time credits, though each continuous run is limited to one hour and concurrency is capped at 20 sandboxes. Pro costs $150 per month plus usage. It extends continuous runtime to 24 hours, supports 100-1,100 concurrent sandboxes, and allows five sandbox creations per second. Enterprise terms are custom. The service suits developers who need configurable, isolated execution and can actively manage usage, sandbox state, and spending limits.

Best for

Developers building AI agents that need isolated code execution
Teams running concurrent agent workloads with measurable compute demand
Organizations that need custom capacity beyond standard Pro limits

Best use cases

Testing agent-generated code without exposing the host application environment

Operating coding or research agents that require terminal and filesystem access

Scaling background automations while tracking running sandbox costs

Compare before choosing

Hobby removes the monthly base fee but caps each continuous run at one hour

Pro adds a $150 monthly fee and raises runtime, concurrency, and creation-rate limits

Enterprise replaces published limits and pricing with a custom agreement

Features

Coding agent execution

Run coding agents with isolated terminal, filesystem, and Git access inside cloud sandboxes.

Deep research agents

Give research agents an isolated computer for code execution, file processing, and tool-driven work.

Automated agent workflows

Run background and computer-use automations while controlling compute allocation and sandbox lifecycle.

Pros

  • Isolated sandboxes reduce the operational risk of running agent-generated code in the host environment.
  • Per-second billing stops when a sandbox is paused, killed, or times out, which supports active cost control.
  • Hobby includes $100 in one-time credits and no monthly base fee, making initial evaluation less expensive.

Cons

  • Compute remains usage-billed, so long-running or highly concurrent workloads can create variable monthly costs.
  • The Hobby plan limits continuous runtime to one hour and concurrency to 20 sandboxes.
  • Pro requires a $150 monthly base fee but does not include additional usage credits.

FAQ

E2B bills automatically at the start of each month for usage incurred during the previous month.
The account is blocked when its credits are exhausted; adding a payment method allows usage to continue.
Teams can set spending limits, monitor active sandboxes, pause idle sandboxes, and kill sandboxes they no longer need.
