🔐 Auth APIs
🔐 Auth APIs help teams add specialized functionality without building the underlying service themselves. This category can be useful when you need proven infrastructure, faster time to launch, and the flexibility to compare multiple providers before you commit. When reviewing options, compare feature coverage, authentication, pricing, documentation quality, and how stable each API feels for long-term production use. A strong category shortlist should make it easier to match your product requirements to the provider that fits your stack, scale, and user experience goals.
