Firecracker microVMs and templates for agent code, sold per running second.
Short answer: One always-on personal agent (2 vCPU / 4 GiB / 20 GiB) costs about $270.89 a month here, with a catch: Sessions end after 24 hours, so an always-on machine has to be restarted by your own code. The AI model adds about $14.70 a month on top (GLM 5.3, 30 requests a day at 40k tokens each, median zero-retention price; from $6.84 at the cheapest host). Fits well: A microVM with its own kernel, Docker, snapshots that keep memory, and up to 20 forks from a running sandbox.
E2B sells isolated sandboxes for agents: a Linux VM created on demand from a template, driven through Python and JavaScript SDKs. It is infrastructure for a product rather than a finished assistant.
Templates define what a sandbox starts with, including images built from Docker images, and the code-interpreter and desktop products run inside the sandbox.
| Who it is for | Developers integrating code execution, data analysis or computer use into an agent product. |
|---|---|
| Isolation | Firecracker microVM with its own kernel, not a container. The default template user is user, not root; root can be set in a template. Docker is documented, but kernel features are not unlimited: the sandbox kernel does not ship xt_owner. |
| Sizes | Sized by vCPU and RAM: up to 8 vCPU, 8 GiB memory on Hobby and Pro, and 10 or 20 GiB of included disk. No GPU on any plan. Regions: US (GCP), US West (AWS), EU and APAC. |
| A personal agent here | About $270.89 a month for one always-on 2 vCPU / 4 GiB machine (2 vCPU / 4 GiB / 20 GiB), before the AI model. The catch: Sessions end after 24 hours, so an always-on machine has to be restarted by your own code. Change the numbers |

Compare: alternatives to E2B · E2B vs Daytona · E2B vs Modal · E2B vs Vercel Sandbox · E2B vs Cloudflare Sandbox
| Model | Per-second usage against a credit balance; Pro adds a monthly plan fee. |
|---|---|
| Meter | $0.000014 per vCPU-second and $0.0000045 per GiB-second of allocated resources while running. Paused and killed sandboxes are not billed. |
| While stopped | Nothing for compute. Volumes and snapshots are separate objects with their own storage. |
| Plan fee | Hobby has no fee; Pro is $150 a month plus usage; Enterprise has a $3,000 monthly minimum. |
| Minimum | No published per-sandbox minimum. Hobby starts with a one-time $100 credit and no card. |
How E2B lets you try before paying is on Trials and free tiers.
| Dashboard | A console exists for support and API keys, but the documented path is SDKs, a CLI and API keys. |
|---|---|
| Without code | No documented no-code path. Examples are SDK calls, terminals and templates; the desktop SDK still needs code to drive it. |
| Signup | No credit card to start, and a one-time $100 credit. When a workspace without a payment method runs out, every project in it is blocked shortly afterwards. |
| Docs and support | Extensive docs with per-page Markdown. Support is through the console. SOC 2 Type II is reported, and a HIPAA BAA can be requested. |
Every capability the guide checks, with the catch where E2B's version falls short. Compare all providers

Shown as the research found them. A contradiction means the provider's own pages disagree; an open question means the answer is not published.
Every sandbox has a timeout defaulting to five minutes, and onTimeout: 'kill' is the default. Pausing instead is opt-in.
The pricing page says the default is 2 vCPU / 4 GiB; the billing docs say 2 vCPU / 512 MiB. Both are current provider statements.
Volumes persist across sandboxes but file locking can hang, metadata caching is disabled and snapshots are not supported.
There are no dedicated or static egress addresses, including Enterprise; a customer-operated proxy is the documented workaround.
A sandbox's public URLs are reachable by anyone who knows them.

It cannot run this exactly as described: 50 GiB of disk is over the 10 GiB limit. Sessions end after 1 hour, so an always-on machine has to be restarted by your own code.
