ReadMe: Pricing, Features & Alternatives

ReadMe is aimed squarely at public API products: developers log in, see their own API keys injected into every example, try calls from the docs, and you see the resulting request logs and per-endpoint adoption metrics. That feedback loop — which endpoints get called, which error, who dropped off — is what separates it from a static docs generator.
