FintX vs protoc-gen-doc

FintX is a native desktop gRPC test bench for functional and performance testing, available on Linux, macOS and Windows. Functional tests compare actual responses with expected responses and show a visual diff. Load testing supports incremental, constant and burst scenarios. FintX can mock external gRPC services, including unary and streaming methods, with responses customized through C# scripting. It generates test data from protobuf definitions using Faker.js/Bogus. To create a gRPC client, users can supply a.proto file or the HTTP location of a gRPC Reflection Server; generated C# client code is compiled into an assembly and saved locally for reuse. Data is stored as text files on the local machine. The free Community plan includes unlimited gRPC clients, request auto-save, import and export, method tabs, a JSON editor and projects. Professional is $100 per seat and adds functional tests, validation rules, visual diffs, test collections, summarized reports and performance testing. Enterprise is $995 for unlimited users.

protoc-gen-doc is a documentation generator plugin for the Google Protocol Buffers compiler. It turns comments in .proto files into HTML, JSON, DocBook, or Markdown documentation, covering files, messages, fields, services and methods, enums and values, and extensions. It supports proto2 and proto3, including both in the same context. You can exclude files with path patterns and omit comments marked with the @exclude prefix. The plugin runs through protoc with the --doc_out and --doc_opt options; its source_relative flag places generated output in the same relative directory as the input. For customization, users can supply a Go template or use a stylesheet.css file to change HTML appearance. Installation options include Go, prebuilt releases, a Docker image, and a Maven Central package. It runs on Linux, macOS, and Windows and is self-hosted.
