Billing & Usage

LaunchGate uses usage-based billing with plan tiers.

Plans

Plan	Monthly runs	Retention	Overage
Free	500	14 days	Hard block (402)
Pro	15,000	1 year	$3 per 1,000 runs
Scale	100,000	1 year	$1.50 per 1,000 runs
Enterprise	Unlimited	Custom	N/A

One run = one completed POST /v1/run call.

On the Free plan, exceeding 500 runs returns HTTP 402. Upgrade to Pro or Scale for automatic overage billing.
