OpenAPI (formerly Swagger) is the standard for describing REST APIs. Swagger UI for documentation, codegen for clients/servers, and a massive ecosystem of tools.
Reviewer scorecard
“The most feature-complete flag platform. Targeting rules, segments, and experimentation are production-grade.”
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“Expensive for what amounts to conditional logic. PostHog flags, Vercel Flags, or Unleash cover most needs at lower cost.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“Feature flags as infrastructure for safe deployment will be universal. LaunchDarkly defined the category.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
