$ hopx sandbox create --ready-in 100ms

Isolated Sandboxes for AI Agents.
Ready in ~100ms.

Give every AI agent, script, and job its own isolated sandbox environment. Full filesystem access. No host exposure. Scale to thousands of concurrent sandboxes — powered by hopx.ai.

No credit card required

01

~100ms Cold Start.
Full Isolation.

Each AI sandbox environment spins up in approximately 100 milliseconds. Your agent gets a fully isolated filesystem, network namespace, and compute allocation — with zero access to the host system. Run untrusted code, install packages, and write files without risk.

  • ~100ms cold startsandbox environments provision faster than a network round-trip. No queuing, no warm pools required
  • Full filesystem accessagents can read, write, and execute files in an isolated /workspace directory
  • No host exposuresandboxes run in isolated namespaces. No access to host processes, network, or filesystem
  • Configurable resourcesallocate CPU, memory, and timeout per sandbox. Right-size for each task

Scale to Thousands.
Concurrently.

Run hundreds or thousands of AI sandbox environments at the same time. Each sandbox is independent — one agent's crash or timeout never affects another. Auto-scaling infrastructure handles burst workloads without pre-provisioning.

  • Horizontal auto-scalinginfrastructure scales automatically to match sandbox demand. No capacity planning needed
  • Independent lifecycleeach sandbox runs in isolation. Failures, timeouts, and crashes are contained
  • Auto-cleanupsandboxes auto-destroy after timeout or task completion. No orphaned resources
  • Usage-based billingpay for sandbox compute time, not idle capacity. Scale down to zero between workloads

Works with Claude, GPT,
and Your Custom Agents.

hopx.ai provides a simple API and SDK to create, execute, and destroy sandboxes. Integrate with Claude, GPT-4o, open-source models, or your own custom agents. Use sandboxes for code execution, tool use, file manipulation, and any task that needs an isolated runtime.

  • REST API + SDKsTypeScript, Python, and Go SDKs. Create a sandbox in three lines of code
  • LLM tool useexpose sandbox operations as tools for function-calling models like Claude and GPT
  • Custom base imagesuse any Docker image as your sandbox base — Node, Python, Go, Rust, or your own
  • File I/O built inupload files before execution, download results after. Stream stdout/stderr in real time

Built for teams building
with AI agents.

AI Engineers

Safe code execution for agents

Give your AI agents a sandbox to run code, install dependencies, and manipulate files — without risking your infrastructure. ~100ms startup means agents never wait.

Platform Teams

Secure by default, scalable by design

Provide a managed sandbox service for your entire org. SOC 2 and ISO 27001 compliant. RBAC, audit logs, and usage tracking built in. No more shadow infrastructure.

Security Teams

Zero trust for AI workloads

Every sandbox runs in its own isolated namespace. No host access. No lateral movement. Configurable network policies. Full audit trail of every command executed.

MLOps Engineers

Reproducible AI pipelines

Run each step of your ML pipeline in an isolated sandbox. Consistent environments, deterministic results. No dependency conflicts between concurrent jobs.

DevTool Builders

Embed sandboxes in your product

Add code execution to your SaaS product via the hopx.ai API. Let your users run code safely without managing infrastructure. White-label ready.

questions

An AI sandbox environment is an isolated, ephemeral compute container designed specifically for AI agents and automated workloads. Each sandbox gets its own filesystem, network namespace, and resource allocation. Agents can execute code, install packages, read and write files — all without any access to the host system or other sandboxes. Sandboxes are created on-demand and auto-destroy after use.

Give your AI agents a safe place to run.
