Architecture

Where the decision happens.

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

Orb
After the call

Usage is recorded and billed after it happens. Your app acts on alerts and webhooks, once the calls have already run.

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.

The gap

What you'd still build on Orb.

Teams pair Orb with code of their own. With Limitr, that part is the product.

With Orb, you still build
With Limitr, you get
Enforcement in the product, before the call
Budgets and limits checked in your app before the call
Cost and margin per account
Your cost and your price on every call, so margin per account is live
Simulations that include your costs
Replays of a price change with revenue and cost

Choose Orb if re-rating and invoicing complex, high-volume contracts is the core problem.

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.
