Runners are in private beta: start a trial, then ask Lizard to enable them for your GitHub organization.
Each job boots its own Firecracker VM on Ubuntu 24.04 (Linux x64); Windows, macOS and ARM jobs stay on GitHub.
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.
The CI page publishes only the Medium label (`lizard-medium-ubuntu-2404`); Small and Large labels are not shown.

Plans

Lizard Sandboxes: plans
Plan	Price	Includes
Pro	$19 /month[3]	$19 of usage a month for the whole platform; 40 vCPU of sandboxes at once (20 Small, 10 Medium or 5 Large); 24/120/400 starts per minute/hour/day; 7-day trial with $5 of usage (card required, Small only, 8 vCPU)

Prices

Lizard Sandboxes: prices per size
Size	vCPU	RAM	Disk	Price	Per hour
Small	2	4 GB	5 GB	$0.0162 /h[1]	$0.0162
Medium	4	8 GB	20 GB	$0.0324 /h[1]	$0.0324
Large	8	16 GB	50 GB	$0.0648 /h[1]	$0.0648

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.
