The cloud was built for requests. Agents need machines that remember

Agents need more than a fresh environment for every task. They need machines they can pause, return to, and branch from as work evolves.

  • Pause

    Keep state while work waits.

  • Resume

    Continue where the agent left off.

  • Fork

    Explore another path from a saved snapshot.

Hear it from our customers

“We benchmarked several sandbox providers, and Superserve stood out for its speed and reliability. They helped us launch Lindy’s AI teammates in under a month.”

“Superserve lets us give every user a complete game studio with our engine, Playwright, and build tools, without having to run the infrastructure ourselves. They’ve been one of our most dependable partners.”

Everything an agent needs

Build the environment once, keep everything it does, and decide what it can reach.

Integrations

Bring any harness, drive it from code

Run Claude Code, Codex, or your own agent loop inside the machine, and control it from TypeScript, Python, MCP, the CLI, or the API.

Can I try it for free?

Yes. Start free, no card required. Your agent’s first sandbox runs on a limited free trial. Add a card and choose a plan to continue once the trial credit is used up.

How much does it cost?

Plans start at $20/month, with $20 of usage included. Pro and Enterprise offer bigger sandboxes and higher concurrency. Compare plans and limits →

Is there a time limit on sessions?

Developer and Pro have no fixed session time limit, so agents can work for days or weeks. You can stop or pause a sandbox, or set an auto-pause timeout. Usage is billed for as long as it runs.

What survives a pause?

The whole machine. Files, installed packages, and state are kept, and the agent resumes where it left off.

How is this different from a container?

Every sandbox is its own microVM with its own kernel. No shared kernels or cross-tenant state.

Can we run sandboxes in our own VPC or a customer's VPC?

Yes. We support deploying sandboxes in your own VPC or your customer's VPC. Book a meeting to discuss your setup →

Do agents ever see my API keys?

No. The credentials broker adds them to requests outside the machine, only for hosts you allow.
