# E2B review (2026): is it worth $150 a month? > Cloud sandboxes where AI agents run code and tools Checked Nov 12, 2026 ยท graded Nov 12, 2026 by ToolGPA. 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. - **Category:** AI Agents - **Made by:** FoundryLabs, inc. (E2B) - **Website:** https://e2b.dev - **Runs on:** Web - **Who should skip it:** Pricey if you move to Pro: $150 a month before any sandbox usage. - **Facts last checked:** Nov 12, 2026 ## Pricing As of Nov 12, 2026, E2B is a paid product with a free trial, starting at $150 per month, plus per-second sandbox usage. - **Pricing model:** Free trial - **Free plan:** None. - **Free trial:** Free Hobby tier with a one-time $100 usage credit, no credit card required. Credits do not renew. | Plan | Price | What you get | | --- | --- | --- | | Hobby | $0 | One-time $100 usage credit, sessions up to 1 hour, 10 concurrent sandboxes and the default sandbox CPU and RAM. Usage is charged against the credit. | | Pro | $150 per month, plus usage billed by the second | Sessions up to 24 hours, 100 concurrent sandboxes (expandable to 1,100 with add-ons at +$500 and +$1,000 a month) and custom sandbox CPU and RAM. | | Enterprise | Custom | Committed usage, custom billing, multi-day sessions, bring-your-own-cloud. The page says it starts at a $2,000 monthly commit. | Read from https://e2b.dev/pricing on Nov 12, 2026. Prices change, so confirm with E2B before buying. ## Ways to pay less - **$20,000 in credits and Pro for early-stage startups** (Startups): A one-time $20,000 in credits plus the Pro tier for startups under three years old that have raised less than $5M. Source: https://e2b.dev/startups ## 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. ## Good for - Teams building coding or data-analysis agents that must execute untrusted code - Developers who want the open-source runtime and an SDK-first workflow - Companies that need sandboxes inside their own cloud account ## 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. ## ToolGPA grades **GPA: 1.8 out of 4**, graded Nov 12, 2026. 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. - **Value for money: D.** Pro is $150 a month plus usage by the second, far above the $52 where the dearest tenth begins. - **Free plan and trial: C.** Hobby is a one-time $100 credit with no card, and credits do not renew, so it is a trial and not a free plan. - **Features: C.** Sandboxes, snapshots, pause, bring-your-own-cloud and MCP tools, though Hobby caps sessions at 1 hour and 10 concurrent sandboxes. - **Ease of use: D.** No store rating on record. It is used through the SDK and API, with a console beside it. - **Platforms and integrations: B.** Web only, with six integrations, Python and JavaScript SDKs and bring-your-own-cloud. These are ToolGPA's own grades. Graded from this listing, whose facts were read from E2B's own pages on 12 November 2026. Not based on using the product, and shorter than our full reviews. ## Where it stands among AI agents - 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.

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. - You could not: An AI agent, with the models and the safeguards behind it. - You could not: It plugs into other products, OpenAI Agents SDK, Claude Code and Codex among them, and has an API. A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it. ## Works with OpenAI Agents SDK, Claude Code, Codex, AWS, Google Cloud, Azure **Tags:** AI agents, Open source, Public API, AI features ## Alternatives - [Browserbase](https://toolgpa.com/tools/browserbase): Cloud browsers and APIs for agents that use the web.
