Instant sandboxes with memory.
Firecracker microVM sandboxes for AI agents. Boot in under 200ms (p50 179ms) with persistent memory across sessions, pause/resume, snapshots and forks, and a real Linux runtime. Perfect for AI-powered development and automation.
Sandbox API
POST /api/sandboxes/create
Powered by Firecracker microVMs — the same technology AWS Lambda uses.

p50 179ms snapshot restore
Memory Overhead
Minimal resource footprint
Isolation
Hardware-level security
Networking
Complete network stack
Firecracker microVMs restore from a snapshot in ~180ms (p50 179ms). No waiting, no containers — instant execution for AI agents.
Agent memory survives sandbox deletion. State, files, and context persist across sessions via snapshots.
Pause sandboxes to save costs, resume instantly when needed. Transparent auto-resume on API calls.
Real Linux runtime with pip, npm, git, curl, and more. Run any command, install any package.
Each sandbox gets a public HTTPS URL. Perfect for live apps, internal tools, and API endpoints.
Create snapshots of any sandbox state. Use them as templates to spin up pre-configured environments.
Integrate with Model Context Protocol, use our SDKs (Python, Node.js, Go), or control via CLI.
Each sandbox runs in its own Firecracker microVM. Complete isolation with minimal overhead.
Track CPU, memory, network usage in real-time. Set limits and get alerts when thresholds are hit.
From code execution to ephemeral environments — sandboxes that adapt to your workflow.
