It is best understood as the graphical sibling of grpcurl: grpcurl is the CLI, grpcui is the interactive web form. ### Project history The official GitHub repository was created in 2018, and its first listed GitHub release was v0.1.0 in January 2019. The README describes grpcui as a browser-based tool for gRPC APIs and explicitly positions it as an extension of grpcurl. grpcui builds on the same general gRPC reflection and descriptor-file model as grpcurl: it can query server reflection, read proto source files, or load compiled protoset files to discover schemas and render forms. ### Adoption history grpcui adoption tracks the growth of gRPC APIs that are inconvenient to test with ordinary HTTP tools. It gives teams a Postman-like workflow for gRPC without needing each developer to write a custom client. Because it is packaged as a single CLI that launches a local web UI, it fits neatly into Homebrew and similar developer-tool package managers. The package is mostly a debugging and exploration tool, not an application runtime. ### How it is used Users run `grpcui` with connection flags for a gRPC server. The tool prints a local URL, starts an HTTP server, and renders service and method selectors plus forms for request messages. It supports plaintext and TLS servers, mutual TLS, request metadata, JSON request entry, response headers and trailers, and descriptor discovery through reflection, proto files, or protosets. ### Why package nerds care grpcui is package-nerd useful because it turns a binary RPC protocol into an inspectable local web tool without requiring a whole desktop API client suite. It also shows a common modern CLI pattern: install a small Go binary from a package manager, then use it to launch a local browser UI for an otherwise hard-to-inspect protocol. ### Timeline - 2018: The grpcui GitHub repository was created. - 2019: v0.1.0 was published on GitHub releases. - 2019: FullStory described grpcui as a way to explore running gRPC interfaces alongside grpcurl. - 2020s: The README documents Homebrew installation and Go installation workflows. ### Related projects - grpcurl is the companion CLI and conceptual base for grpcui. - gRPC server reflection enables grpcui to discover schemas from a running server. - Protocol Buffers and protoset descriptor files provide the schema data grpcui uses to build forms. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** grpcui - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - grpcui: normalized package name match | nixpkgs package indexes: pkgs/by-name/gr/grpcui/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - grpcui - 1.5.1-r9: normalized package name match | Alpine Linux edge package indexes: grpcui from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | Interactive web UI for gRPC, along the lines of postman | https://github.com/fullstorydev/grpcui ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [grpcurl](https://www.automicvault.com/pkg/brew/grpcurl/) - Shares av.db curated category or tags: api-client, api-tools, cli, developer-tool, developer-tools. - [evans](https://www.automicvault.com/pkg/brew/evans/) - Shares av.db curated category or tags: api-client, cli, developer-tools, grpc. - [oauth2l](https://www.automicvault.com/pkg/brew/oauth2l/) - Shares av.db curated category or tags: api-tools, cli, developer-tools, go. - [protoc-gen-grpc-java](https://www.automicvault.com/pkg/brew/protoc-gen-grpc-java/) - Shares av.db curated category or tags: cli, developer-tools, grpc. - [protoc-gen-grpc-swift](https://www.automicvault.com/pkg/brew/protoc-gen-grpc-swift/) - Shares av.db curated category or tags: cli, developer-tools, grpc. - [chiko](https://www.automicvault.com/pkg/brew/chiko/) - Shares av.db curated category or tags: api-client, cli, developer-tools, grpc. - [ghz](https://www.automicvault.com/pkg/brew/ghz/) - Shares av.db curated category or tags: cli, developer-tools, go, grpc. - [ghz-web](https://www.automicvault.com/pkg/brew/ghz-web/) - Shares av.db curated category or tags: cli, developer-tools, grpc, web-ui. ## Combined YAML source View the package source record on GitHub.
