Lizard

Lizard (lizard.build) runs AI agents in fast, low-cost cloud sandboxes and ships what they build.Each sandbox is a Firecracker microVM with its own kernel. Agents run AI-generated or untrusted code there, not on your machine. They get a shell, files, HTTPS URLs for open ports, and a built-in desktop and browser to open and test apps.What you get:Sandboxes that boot in 228 ms median, the fastest in our 300-run test against E2B (264 ms), Daytona (819 ms) and Modal (929 ms)Persistent Volumes that keep files after a sandbox stopsReady templates: base for shell tasks, codex for coding agents, interpreter for PythonUS East and EU West regionsLogs, CPU and memory metrics for every sandboxLizard SDK for TypeScript and Python, Lizard CLI, Lizard MCP and Lizard Skill for coding agentsDeploy the apps your agents build, with Managed Postgres, Managed Redis and S3-compatible storage, and no CI/CD to managePricing: Small (2 vCPU, 4 GB RAM) $0.0162/hour, Medium (4 vCPU, 8 GB RAM) $0.0324/hour, Large (8 vCPU, 16 GB RAM) $0.0648/hour.
