The short answer

Moesif (part of WSO2 since 2025) is strong at product analytics — funnels, cohorts, a year of data. It doesn’t issue keys or rate-limit, and its own guide says rules can take up to 15 minutes to propagate. ReqKey enforces on every request.

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

Why teams pick ReqKey over Moesif.

1

Enforcement on the request

ReqKey deducts credits synchronously. With a 15-minute propagation window, a customer at zero can keep calling.

2

Keys included

ReqKey issues and validates the API keys. Moesif relies on your own auth or gateway for that.

3

Real rate limits

Windows from 1 second to 24 hours, answered with 429 and Retry-After. Moesif has quota rules, not a limiter.

4

Published, flat pricing

ReqKey’s price is public and counts requests, with no per-seat fees on Pro.

When Moesif is the better pick.

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

  • Product and finance teams who need funnels, cohorts, and retention analysis on API usage.
  • You need a year of analytics history out of the box.
  • You invoice through Stripe, Chargebee, or Zuora and want usage synced for you.

Framework guides How ReqKey works

ReqKey vs Moesif: common questions.

Something else? Ask the team or read the docs.

  • Yes. ReqKey enforces keys, credits, and limits in the request; Moesif can keep doing product analytics on the same traffic.

  • On the next request. The check and the deduction happen in the same call, in under 5ms on average.

  • No — ReqKey doesn’t take payment. Your app reads usage from the Analytics API and recharges credits when a payment succeeds.
