Architecture

Where the decision happens.

The difference most comparisons skip: where a call is allowed, priced, and capped, and when.

Stigg
A sidecar next to your app

A separate process serves cached entitlements and credits, and falls back to their API on a miss.

Limitr
Inside your app, before the call

The engine runs natively in your process and decides every call in about a millisecond: allowed, priced at your cost and your price, and held to the contract. Usage goes to Limitr Cloud in the background.

Limitr is built for them. An agent is a customer like any other, with its own plan, limits, and budget, linked to the workspace it works for. Budgets per task, customer, and org are checked in your app before each step runs, and the agent can see what it has left as a Claude tool.
