httpyac - a command line client for executing integration tests for all kinds of requests (gRPC, HTTP, MQTT, Websocket).
protodot - Transforming your .proto files into .dot files (and .svg, .png if you happen to have graphviz installed)
grpc-client-cli - interactive gRPC client
proto2asciidoc - Generate AsciiDoc documentation from a .proto file
proto-to-postman - Create postman API import collection from .proto files

GUI

Postman - Create, test, and debug gRPC services directly from Postman
letmegrpc - Generate a web form gui from a grpc specification
omgRPC (Deprecated) - A GUI client for interacting with gRPC services, similar to what Postman is for REST APIs
grpcui - An interactive web UI for gRPC, along the lines of postman (also, a Go library for embedding these web UIs into Go HTTP servers)
BloomRPC (Deprecated) - A nice and simple GUI Client. Exploring and interacting with gRPC and gRPC-web services has never been simpler, Inspired By GraphQL-Playground and Postman
gRPCox - Like Postman, but for gRPC. web based GUI Client for gRPC, extremely easy to use.
vscode-httpyac - A VSCode extension which supports sending all kinds of requests (gRPC, HTTP, MQTT, Websocket)
Milkman - Extensible alternative to Postman for crafting all kinds of requests, not only for gRPC, also http, sql etc.
MuninRPC - Protobuf request and response testing application under the gRPC system.
Delivery - A simple electron app for gRPC that uses gRPCurl to autodetect all endpoints/methods and their request bodies, just modify the JSON body. Simplicity in mind.
(Yodelay.io) - A browser GUI Making sure your outbound 🗣️ ‘yodelay’ returns the ‘IiiOoo’ 📣 that you expect.
Wombat - A cross platform gRPC client. Auto-generates input fields from your proto files or the gRPC reflection API. Not another Electron app - built with Qt and Go.
Kreya - A gRPC and gRPC-web client supporting environments, templating, authentication schemes and file based syncing.
Plumber - Another one GUI for GRPC requests (reflection only)
Fint - Create, run, manage performance tests and functional tests cases for gRPC service in a single (commercial) tool
Protocall - A browser-based gRPC & protobuf API client. Integrates with Github and automatically resolves all proto imports with no manual configuration.
Grip - Native macOS client for interacting with gRPC services
ezy - 🔥 Fully-featured GUI client for gRPC/gRPC-Web.
Warthog - A cross platform gRPC client. Input generation for all types, including nested and looped messages. Saving requests and servers.
ptg - GUI gRPC client, it is also a performance testing tool.
