- Runner time bills per second at Sandbox prices and draws from the plan's included usage; past it, pay as you go.
- Works for GitHub organizations only, connected by an organization admin; personal accounts are not supported yet.
- A cache disk per private repository keeps Docker layers, a git mirror and lizard-build/cache entries (up to 10 GB); fork jobs start on an empty disk.

### Prices

|---|---|---|---|---|---|---|
| Small | 2 | 4 GB | 5 GB | any | $0.0162 /h [1] | $0.0162 |

- Each size has one hourly price for CPU, memory and local disk, billed per second while running, idle included; a successful pause stops compute charges.
- Pro is $19 a month with $19 of usage included for the whole platform; usage past it is pay as you go at the same rates. Pro 5x ($99) and Pro 20x ($499) include usage equal to their price and raise the limits.
- Concurrency counts vCPU of running sandboxes per account owner (Pro 40, Pro 5x 220, Pro 20x 1,200; Enterprise per contract); paused sandboxes count for nothing.
- The 7-day trial needs a card and includes $5 of usage: Small sandboxes only, US regions only, up to 4 at once.
- Sandbox egress is included up to 2 TB per account over a rolling 30 days; more needs contact with Lizard.
- Persistent Volumes cost $0.14 per used GB a month and attach to one sandbox at a time on node-local storage.
- Sandboxes are Linux and CPU-only; no self-hosting, Windows or macOS.
- The 228 ms start time (median of 300 starts on 2026-10-12, Small, us-east-1) is Lizard's own measurement.
- Sandboxes created before sizes existed keep their original usage-based billing; Lizard publishes no rate for them.
