Does ReqKey capture request bodies?

Optionally. Headers, bodies, and client IPs are opt-in, sensitive headers can be excluded, and keys are always stripped before anything is logged.

Yes — they’re both middleware. Many teams keep an observability tool and add ReqKey for keys and credits.

Is ReqKey billed yearly?

No. Pro is month-to-month from $25.

The short answer

Treblle is API intelligence: observability, auto-generated docs, and quality scoring. It doesn’t issue keys, meter credits, or block anything. If you sell your API, ReqKey covers the enforcement Treblle leaves out, at a lower entry price.

Treblle is an API observability. ReqKey is API keys, credits, rate limits, and request analytics for the API you sell.

The Analytics API lets you build customer-facing usage dashboards from the same data.

When Treblle is the better pick.

We’d rather you pick the right tool than switch twice.

You want auto-generated API docs and API quality scoring.
You need governance and compliance tooling across many APIs.
Auth and billing are already solved elsewhere and you only need observability.

Moving from Treblle in three steps.

1
Create plans with the limits you use today
Each plan carries its credits, refill interval, and rate limit, so the numbers leave your code.
2
Issue keys to your customers
One consumer per customer, one or more keys each — they all draw on the same balance and limit.
3
Swap the middleware
Replace the limiter with the ReqKey middleware for your framework. Keep the old one on anonymous routes if you like.
