What it does
InstaBox gives each AI agent its own Linux machine in the cloud: a Firecracker microVM running Debian, with Docker, common language runtimes, a desktop and Chromium in the default template. Agents and developers create, run, pause, fork and snapshot machines through a CLI, an HTTP API, TypeScript and Python SDKs, or MCP tools for Claude Code, Cursor, Codex, OpenCode and Antigravity. Machines can expose web servers on HTTPS URLs and show their desktop for an agent to drive. Pricing is a free plan plus paid plans that include monthly usage credits.

- A machine per agent. Each agent gets its own Firecracker microVM running Debian 13, started with one command. Official source 1 ↗
- Ready-made templates. The default template ships Docker, Node.js, Bun, Python, Go, Rust, OpenJDK 21, a desktop and Chromium; an Android template adds Android 14 with adb. Official source 1 ↗
- Fork and snapshots. Copy a machine's disks into new machines in seconds, or save a machine once and start new ones from it. Official source 1 ↗
- Public and private ports. Give a web server in a machine an HTTPS URL, open to anyone or only to people with the link. Official source 1 ↗
- Desktop an agent can drive. Watch a machine's desktop, let an agent control it, and share a link to it. Official source 1 ↗
- MCP and SDKs. Machine tools over MCP for Claude Code, Cursor, Codex, OpenCode and Antigravity, plus TypeScript and Python SDKs and an HTTP API. Official source 1 ↗ · Official source 2 ↗
- Org secrets and agent sign-up. An outbound proxy adds org-scoped credentials to HTTPS headers, and an agent without a browser can sign itself up for the owner to approve. Official source 1 ↗
