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
“API collections in git, no account required, and offline-first. This is how API clients should work.”
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“One-time purchase vs subscription is refreshing. Git-native collections mean your API tests are version-controlled.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“Offline-first, git-native tools represent a pushback against SaaS subscriptions. Bruno leads this movement in API tools.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
