Limitr FAQ
What’s the difference between a billing platform and Limitr?+
A billing platform records usage after the fact and invoices later, while Limitr decides what’s allowed and meters it at the moment of consumption.
Do I have to monetize if I only want to control usage?+
No. You can configure policies to only monitor or limit usage without charging.
Can Limitr handle any pricing model?+
Yes. It supports usage-based, seat-based, hybrid credits, trials, rollovers and custom enterprise deals via a single policy format.
Is Limitr only for AI companies?+
No. It can meter any definable unit such as API calls, SMS, storage, GPU seconds, or custom credits.
Does Limitr just track usage or also enforce and bill?+
It does all three: it tracks, enforces limits in-process, and streams usage events for billing.
