What is E2B?
Secure cloud sandboxes for agent code execution.
Who is E2B best for?
E2B is best for teams building AI agents that need to run code, browse or drive a desktop in isolated sandboxes.
Coding agents
Each agent session gets its own Linux microVM with a shell, filesystem and network, so generated code runs apart from your own systems.
Reinforcement learning and evals
Thousands of sandboxes can start, run and shut down in parallel, which suits RL rollouts, agent evaluations and benchmarks.
Computer-use agents
The Desktop sandbox adds a screen, mouse and keyboard with a live stream, so an agent can operate desktop apps like a person.
Teams with strict data rules
Sandboxes can run inside your own AWS or GCP account, and E2B is SOC 2 Type II and HIPAA compliant.
How much does E2B cost?
E2B's Hobby plan has no monthly fee and comes with a one-time $100 usage credit, Pro costs $150 a month, and on both you pay for sandbox time by the second on top.
- $100 one-time usage credit, no card needed
- Sessions up to 1 hour, 20 sandboxes at once
- Default sandbox CPU and RAM
- Sessions up to 24 hours
- 100 sandboxes at once, up to 1,100 with add-ons
- Custom sandbox CPU and RAM
Usage is billed by the second while a sandbox runs: 2 vCPUs (the default) cost $0.000028 a second, about $0.10 an hour, and each GiB of RAM costs $0.0000045 a second. Disk is included: 10 GiB on Hobby and 20 GiB on Pro. Pro's concurrency add-ons cost $500 a month for 600 sandboxes or $1,000 a month for 1,100. Hobby's $100 credit is given once, and Pro adds no credit. Enterprise has custom pricing with a $3,000 a month minimum, multi-day sessions and deployment in your own cloud. Full pricing on e2b.dev.

Where can I try E2B?

What happens when E2B's $100 credit runs out?
E2B blocks the account once the one-time $100 Hobby credit is used up. Add a payment method to keep going; Hobby still has no monthly fee, so you then pay only for per-second usage, and you can set a spending limit in the dashboard.
Do I pay for paused E2B sandboxes?
No. E2B bills only while a sandbox is running, and billing stops as soon as it is paused, killed or times out. A paused sandbox keeps its state with no time limit on every plan, and auto-pause can pause idle sandboxes for you.
