Time to value

Quick Setup (< 1 hour)

You can use Limitr to define, track, and enforce usage limits across your applications. It runs directly inside your codebase using WebAssembly to evaluate customer entitlements, calculate costs, and block overages in microseconds without external latency. You write pricing policies in JSON, YAML, or TOML, allowing you to update plans, discounts, and quotas without redeploying your code. Limitr syncs usage data asynchronously to background billing systems like Stripe, letting you track margins, handle seat or token billing, and enforce custom enterprise contracts.
