Many teams suffer from API development pain points: inconsistent frontend-backend interface contracts, repetitive SDK writing, difficult-to-maintain documentation... After the emergence of OpenAPI Generator, API development efficiency has been completely revolutionized.
It automatically generates client SDKs, server stubs, documentation, configurations, and more based on OpenAPI specifications, supporting 50+ client languages and 40+ server frameworks, completely transforming "contract-first development" from concept to productive practice.
OpenAPI Generator is an open-source project that automatically generates client SDKs, server skeletons, documentation, and configuration files by parsing OpenAPI v2/v3 specification documents.
It supports dozens of programming languages and frameworks. It is the community continuation and enhanced version of swagger-codegen, being more modular, community-driven, and supporting extensive custom templates. The engine is based on the Mustache template engine, allowing customization of output structure or format.
