Lizard is a cloud for AI agents: Lizard Sandboxes to run the code they write, and a platform to deploy the apps they build.
Lizard Sandboxes are Firecracker microVMs, each with its own kernel. In a test on 2026-10-12 (300 runs, base template, Small size), the median time from creating a sandbox to its first Python output was 228 ms (p95 310 ms), the lowest against E2B, Daytona and Modal (benchmark). The Small size (2 vCPU, 4 GB RAM) costs $0.0162 per hour, billed by the second. There are 8 templates (base, interpreter, codex, claude, opencode, pi, prime, desktop) and sandboxes run in the US and EU. A sandbox can pause, resume, snapshot and fork with its memory and running processes.
