Sandboxes and CI, on providers you already use

Scale your sandboxes. Choose your zoib and run.

Works with any AI agent: CLI, MCP, API. Paste this into yours:
Read https://zoib.io/llms.txt, then set up zoib for this repo.

A sandbox is a fresh computer in the cloud for your code, your tests or your AI agent. zoib takes you from 2 sandboxes to as many as you need, across the providers you already use, with your own keys. And it runs your CI on them too.

Start in 60 seconds ↓What's a sandbox?

From 2 to N. You never touch a provider.

Same 3 steps for you and your agent
  1. 1

    Sign in

    We email you a code. No keys to copy.

    zoib login --email you@company.com
    Request early access
  2. 2

    Connect a provider

    Add a key for a provider you already use.

    zoib provider add instabox --key-file ./instabox.key

    Your own keys. We never sell compute.

  3. 3

    Run a sandbox

    Run your tests in a fresh box.

    zoib run --from . -- npm test

    zoib places it on a provider, and switches when one is full or down.

Commands are examples until the CLI lane confirms them.

What's a sandbox?

A sandbox is a fresh computer in the cloud. You start it in seconds, run your code in it, and throw it away. Nothing you do there can break your laptop or production.

Run your testsEvery PR gets clean machines. That's CI.
Give an agent a safe placeYour AI agent writes and runs code in a box, not on your laptop.
Preview a branchStart the app from any branch and share the link.
Try anythingA new library, a risky script, a big data job. Then delete it.
From 2 to N · same command (example)
$ zoib run --count 200 --from . -- npm test
# 120 on boat, boat at its limit
# 80 more on lizard

Two problems we solve

CI

CI is slow, queued and costly, and someone babysits it.

zoib runs your jobs on your own providers, split across many boxes at once.

Providers

Every sandbox provider has its own API, keys, limits and bill.

zoib gives you one API, CLI and MCP over all of them, with your own keys.

Provider Factory

A new provider in hours, not months.

Not listed? Ask, and our agents build it.

Runner

For CI.

Your GitHub Actions jobs run in fresh boxes on your own providers, split across many at once. No queue, no babysitting.

ZB-02

Carrier

For many sandboxes.

One API, CLI and MCP over every provider. From 2 boxes to N, warm and ready. When a provider hits a limit, it switches.

zoib run --count 50 --from . -- npm test
ZB-03

Scout

For your first box.

One sandbox for you or your AI agent, in seconds. Try code safely, then throw it away. The easy way in.

zoib run --from . -- bash
05

For agents

zoib is built so AI agents can use it on their own. Point your agent at one file and it knows the rest.

  • MCP server, CLI and API: the same actions everywhere.
  • --json on every command. Waits and streams, so agents don't poll.
  • Errors that say what went wrong and the next step to take.

Your keys. Your bill. Our machine.

We never sell compute. You keep your provider accounts, prices and data. zoib adds teams, budgets, warm pools and audit on top.
