Limits worth knowing in E2B
- Usage is billed separately from the plan: for example a default 2 vCPU sandbox costs $0.000028 per second and 4 GiB of memory $0.000018 per second.
- The free Hobby tier is a one-time $100 credit, not a renewing allowance, and caps sessions at 1 hour and 10 concurrent sandboxes.
- Going from 100 to 600 or 1,100 concurrent sandboxes adds $500 or $1,000 a month on top of Pro.
- It is infrastructure for developers: there is a web console but the product is used through the SDK and API.
