[ Infrastructure ]

Built on Firecracker.

Every sandbox is a dedicated microVM. The same technology AWS uses to isolate Lambda and Fargate. Hardware-level isolation, sub-300ms cold starts, and true multi-tenant security. No shared kernels, no container escape surface.

[ Platform ]

Built for production.

Everything you need to run untrusted code at scale.

[ Use cases ]

Built for the workloads AI creates.

Coding agents, data analysis, code interpreters, and per-user sandboxes in AI apps. Any code that needs to run somewhere other than your server.

Coding agents

coding-agent:~/repo
1const sb = await Sandbox.create()2await sb.commands.run("git clone <repo>")3await sb.commands.run("npm test")

Code interpreter

interpreter:~/python
1const sb = await Sandbox.create()2const r = await sb.commands.run("python -c 'print(2+2)'")3console.log(r.stdout) // "4"

Per-user sandboxes

per-user:~/user-42
1const sb = await Sandbox.create({2  metadata: { userId: "42" },3})

Long-running research agents

research:~/paper-analysis
1const sb = await Sandbox.create()2await sb.commands.run("python research.py")3// runs for days, survives restarts

[ Open source ]

Built in the open.

Superserve's SDK and runtime are both open source. Read the code, file issues, open PRs. We ship in public.
