gnostic is a Go command-line compiler that converts OpenAPI descriptions between JSON/YAML and Protocol Buffer representations. It provides type-safe protobuf models for OpenAPI, error reporting, dependency resolution, and a plugin interface for code generation and other API tooling.

Use cases

• convert OpenAPI specs to protobuf representations
• generate code from OpenAPI descriptions
• lint and validate OpenAPI documents
• work with OpenAPI specs in type-safe Go or Dart code
• transcode protobuf APIs to OpenAPI documents
• build custom API tooling via the gnostic plugin interface

When to choose

• you need programmatic, type-safe access to OpenAPI descriptions
• you want to build code generators or linters on top of OpenAPI specs
• you need to convert between OpenAPI JSON/YAML and protobuf formats

When to avoid

• you just need simple OpenAPI documentation rendering
• you need a stable 1.0 tool and cannot tolerate prerelease changes
• your toolchain has no Protocol Buffer support
