Best for secure sandboxes for running AI-written code
E2B runs isolated sandboxes for code that AI agents write, through Python and JavaScript SDKs. Hobby is a one-time $100 credit and Pro is $150 a month plus usage by the second. It is infrastructure for developers, and more concurrent sandboxes cost $500 to $1,000 a month on top.
Who E2B is for
- Fits if you build agents that run code and need an isolated place to run it
- Works for a developer who wants a $100 credit before paying
Who E2B is not for
- Pricey if you move to Pro: $150 a month before any sandbox usage
- Watch out: a default 2 vCPU sandbox is billed at $0.000028 a second and memory separately
- Tight if you scale: 600 or 1,100 concurrent sandboxes add $500 or $1,000 a month
- Not for you if you need a free allowance that renews, as the $100 credit does not
- Skip it if you want a no-code product, as it is used through SDK and API
Why E2B gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for moneyPro is $150 a month plus usage by the second, far above the $52 where the dearest tenth begins.
- CFree plan and trialHobby is a one-time $100 credit with no card, and credits do not renew, so it is a trial and not a free plan.
- CFeaturesSandboxes, snapshots, pause, bring-your-own-cloud and MCP tools, though Hobby caps sessions at 1 hour and 10 concurrent sandboxes.
- DEase of useNo store rating on record. It is used through the SDK and API, with a console beside it.
- BPlatforms and integrationsWeb only, with six integrations, Python and JavaScript SDKs and bring-your-own-cloud.

E2B's GPA of 1.8 is higher than 11 of the 101 other AI agents we grade, and level with 14.
It stands best on platforms and integrations (B, above 20 of 101) and worst on value for money (D, above 0).
Its paid plans start at $150 a month, against a middle price of $22.13 for the category: 62 of the 65 others that charge start lower.
On features, ease of use and platforms it scores 2.0 out of 4. 55 tools score higher and cost less.

Keep E2B, or make your own?
Keep it
To replace E2B you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 76 of the 101 other AI agents grade higher. It costs $1,800 a year. E2B is open source, so there is a third way: take its code and run it yourself.
What you could not
- An AI agent, with the models and the safeguards behind it.
- It plugs into other products, OpenAI Agents SDK, Claude Code and Codex among them, and has an API.
What this rests on. E2B’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is E2B?
E2B runs an isolated machine for each agent session, so an AI agent can execute code, use a shell and filesystem, and reach tools without touching your own systems. It is used through Python and JavaScript SDKs and runs on E2B's cloud or inside your own AWS, GCP or Azure account. The sandbox runtime is open source under Apache-2.0.
Worth knowing
- 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.
Key features
- Isolated sandbox per session
- Each agent session gets its own microVM with a shell, filesystem, network and an optional browser or desktop.
- Snapshots and pause
- Sandboxes start from a snapshot, and a sandbox can be paused and resumed from the same state.
- Python and JavaScript SDKs
- The sandbox is created and controlled from code with the e2b package for Python or npm.
- Bring your own cloud
- The same SDK works on E2B Cloud in the US, EU and APAC or inside your own AWS, GCP or Azure account.
- MCP tools inside the sandbox
- The site says more than 200 MCP servers can be called from inside a sandbox, and secrets are scoped per sandbox.
- Per-second usage billing
- Running sandboxes are charged by the second for vCPUs and memory, so cost follows run time and size.
