FintX vs ghz

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. The linked privacy policy contains placeholder text rather than substantive privacy details.

ghz is a command-line utility and Go package for load testing and benchmarking gRPC services, including local debugging and performance regression checks in CI. Tests can define a service with a.proto file, a compiled protoset bundle, or server reflection, and exercise unary, streaming, or duplex calls using JSON or binary data. Load schedules include constant, step, and linear request rates. Go templates can generate request data and metadata for each call using values such as worker ID, request number, method name, and timestamps. The CLI can emit summary, CSV, JSON, pretty JSON, HTML, Prometheus text exposition, and InfluxDB line protocol results. Documentation also covers InfluxDB output, Prototool, and prebuilt Grafana dashboards. The complementary ghz-web application is labeled beta; it stores reports in projects for viewing and comparison over time, and supports SQLite, MySQL, or PostgreSQL storage. It accepts reports through ingest endpoints. The project is identified as Apache-2.0 licensed. Installation options include prebuilt executables, Homebrew, and building from source. The CLI is listed at free; the web companion is beta.
