StateSet Sandbox

Run AI agents in production with isolated execution, reliable file I/O, and predictable costs.

What it is

Production runtime for agent workflows

StateSet Sandbox is a Kubernetes-backed runtime that gives each agent its own secure sandbox. Use a simple API to execute commands, read/write files, and store artifacts without running your own workers.

Why it matters

Execution you can ship to production

Shared runners are risky and hard to govern.
Local setups are brittle and do not scale.
Agent workflows need reliable execution and clean I/O paths.

How it works

1. Create

Spin up a sandbox in seconds.

2. Execute

Run commands and tools safely.

3. Write

Base64-safe file writes.

4. Read

Fetch files reliably.

5. Store

Upload artifacts for reuse.

6. Stop

End sessions when work is done.

Built for Claude Code

Claude Code CLI ships in the sandbox image with BYOK support.

Run agent tasks with `claude -p` inside a sandbox.
Use MCP integration to expose sandbox tools to Claude.

Key features

Isolated pods per agent

Each sandbox runs in its own Kubernetes pod with timeouts and resource limits.

Reliable file I/O

Base64-backed read/write paths avoid WebSocket hangs and binary corruption.

Fast provisioning

Warm pools keep execution responsive for agent loops.

Artifacts and checkpoints

Persist outputs or restore entire workspaces across runs.

API + SDKs

Node and Python SDKs plus a CLI and dashboard for visibility.

Deployment options

Hosted API

Fastest way to get started

Use the StateSet-managed API for quick onboarding and automatic upgrades.

Self-hosted

Bring it to your cluster

Deploy the controller on your Kubernetes cluster to control networking and data.
