rt.create()
Two shapes, one API
A disposable box for untrusted code, or a persistent agent home that keeps working between sessions. Same call, different lifetime.
The managed cloud for AI agents.
Give your agent compute, networking, a domain, a filesystem and a database — not just a sandbox. Run it on our fleet, or your own.
what you get
A managed runtime,
not another sandbox API.
managed volumes
Storage that outlives the box
Attach a managed volume and the data survives the box it was created in. Up to 120 GiB of storage per box.
lifecycle: managed
Idle-stop, wake on access
Boxes stop when they go idle and wake when something touches them. You don't babysit the lifecycle.
BOXLITE_REST_URL
Same SDK. A URL and a key.
Python, Node.js, and the CLI, against the same core API you use locally. Point the SDK at the REST URL and pass an API key.
quickstart
A URL, a key,
and a thousand boxes.
Create an API key in the console, export two environment variables, and the SDK you already know points at the managed runtime. Handing /agent.md to a coding agent works too — every snippet in it is executed against the live API before release.PYTHONCloud quickstart

Built for the agentspeople actually ship.
RUN CLAUDE CODE IN A BOX
An autonomous coding agent confined to a microVM.
The agent gets root inside its own kernel and nothing at all outside the box.
BUILD A CODE INTERPRETER FOR YOUR LLM
A model writes Python; it executes in a disposable microVM.
Generated code never touches your host, and the box is thrown away when it is done.
REVIEW UNTRUSTED PULL REQUESTS
Tests and an automated review of code you have not read.
Clone the PR into a box, run the suite, then read the diff - with no access to your machine.
BUILD A DATA ANALYSIS AGENT
CSV in, model-written pandas analysis and a chart out.
The model installs what it needs and writes files; you get the artifact back.
SCRAPE AND ANALYZE THE WEB SAFELY
A browser box plus a parsing box, feeding clean data to a model.
Playwright and CDP are ready in the browser box; parsing runs in a separate one.
GIVE EACH USER A PERSISTENT SHELL
A live, stateful shell per user, branch, or agent.
State survives stop and restart, so every user or branch keeps its own environment.
local or cloud
Same runtime. Local or Cloud.
Cloud is the same SDK and the same core API as the local runtime — reached over a URL instead of loaded in-process.| Local | Cloud | |
|---|---|---|
| Where boxes run | Your laptop, your servers, air-gapped | BoxLite's managed fleet |
| How you reach it | In-process library, no account | REST URL + SDK |
| You operate | Hosts, image cache, capacity | Nothing |
| Isolation | Hardware microVM, own kernel | Hardware microVM, own kernel |
| Storage | Your own disk | Managed volumes and cloud disks that outlive the box |
| Box lifecycle | You manage it | Idle-stop and wake-on-access |
| Concurrency | As far as your own hardware goes | Thousands of concurrent boxes |
| Support | Discord and GitHub issues | Dedicated support for Cloud customers |
| Best for | Local dev, embedding in your app, on-prem | Production agents, bursty scale, teams |
pricing
Pay as you go, or take a plan.
Plans come with a usage allowance that resets each cycle; anything beyond it draws from a prepaid wallet. You can also run wallet-only with no subscription at all.Starter

- $250 included usage each cycle
- 100 concurrent boxes
Max
$499per month
Fleet-scale parallel agents.
- $900 included usage each cycle

Per-box ceilings apply on every plan: 4 vCPU, 32 GiB memory, 120 GiB storage. Included quota covers usage first; a prepaid wallet funds the rest. Full billing docs
faq
The questions people actually ask.
Yes. The docs describe Cloud as a hosted agent runtime built on BoxLite — the same SDK and the same core API, reached with a URL and an API key, with managed storage and a managed box lifecycle.
