How it works

Three steps. Zero friction.

01
📦

Send your files

POST your code as JSON, zip, or via CLI. Static sites, Node.js, Python, Bun — pick your runtime.

02
💰

Pay inline

x402 protocol handles payment automatically. Your AI agent's wallet pays in USDC on Base. No signup, no API key.

03

Get a live URL

Sandbox spins up in under 30 seconds. You get a URL, SSH access, and logs. Auto-expires after your chosen TTL.

Features

Everything an agent needs. Nothing it doesn't.

Payment

x402 native

Built on Coinbase's x402 protocol. AI agents pay with their Agentic Wallet — USDC on Base. Machine-to-machine, no human in the loop.

Access Control

Token-gated previews

Sandboxes aren't publicly indexed. Access via token URL, IP whitelist, or open mode. No accidental exposure.

Runtimes

Static, Node, Python, Bun

Pick your runtime. Set build_cmd and start_cmd. Environment variables included. It just works.

Lifecycle

Auto-expiring sandboxes

Every sandbox has a TTL (1h to 7 days). Extend with one call. Delete early and get a prorated refund. Zero cleanup.

Security

Sandboxed by default

No outbound SMTP. Rate-limited egress. CPU/RAM caps. Content scanning. Economic barrier to abuse. No KYC needed.

MCP Server

Agent-native tooling

MCP server for Claude Code, Cursor, Cline. Your agent gets a deploy_sandbox tool. User says "put it online" → done.

Observability

Live logs & SSH

Stream logs via SSE. SSH into your sandbox on port 2222. Debug in real-time, just like a real server.

SDK

One-liner in any language

NPX CLI, Node.js SDK, Python SDK. Or just raw HTTP — it's a simple REST API. No client library required.

Use cases

Who needs this?

🤖

AI Agents

Agents that build apps and need to deploy them. Claude Code, Devin, Cursor — they all need a "put it online" tool.

🎨

Quick Demos

Show a client a prototype without spinning up infrastructure. Live URL in 30 seconds, gone in 72 hours.

🧪

CI/CD Previews

Deploy every PR to a live sandbox. Review the actual app, not just screenshots. Tear down automatically.

📚

Education

Students deploy their projects instantly. No server setup, no hosting accounts. Learn to code, not to configure AWS.

Pricing

Pay per sandbox. Refund unused time.
