| API | ghz-web provides ingest endpoints for raw JSON reports, including an endpoint that creates a project automatically. | The documented endpoints include service registration, listing services, calling a gRPC method, and returning API documentation for Swagger UI. |
| Integrations | The documentation includes prebuilt Grafana dashboards and describes InfluxDB output and use with Prototool. | The README describes integration with swagger-ui and use of the gRPC reflection feature. |
| License | The GitHub repository identifies the project license as Apache-2.0. | The repository provides the software under the MIT License. |
| Purpose | ghz is a command line utility and Go package for load testing and benchmarking gRPC services, including local debugging and performance regression testing in automated CI environments. | gRPC Swagger is a debugging tool that uses gRPC reflection and Swagger UI to list and call gRPC methods. |
| Support | The site links to the guide, Go documentation, GitHub repository, and a community support link labeled “Say Thanks!”. | The README invites users to open an issue or pull request to contribute. |

In their own words
ghz
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.
gRPC Swagger
gRPC Swagger is a free, open-source debugging tool for discovering and calling gRPC methods through Swagger UI. It uses server reflection to scan a registered endpoint, identified by host and port, and then displays available services, method definitions, and parameters. Users can invoke methods with Swagger UI’s “Try it out” control, supplying request data and headers as JSON; the headers are passed to the gRPC server as metadata. Reflection must be enabled on the gRPC service, but the setup instructions say proto files and related implementations do not need modification. The project runs from a released JAR or from source and defaults to port 8080. Configuration can show registered services and expire inactive registrations after a chosen number of seconds. Documented endpoints cover registration, service listing, method calls, and Swagger documentation. It is self-hosted, available for API and web use, and licensed under MIT.
