What WireMan is

WireMan is a free, open-source terminal gRPC client for Linux developers testing gRPC endpoints. It reads .proto files named in a configuration file and supports unary, server-side streaming, client-side streaming, and bidirectional streaming methods. When available, server reflection can be used with optional authentication headers. Requests can carry authentication and metadata headers, including bearer tokens supplied by a shell script. WireMan keeps request history and autosaves it by default, and the current request can be copied as a grpcurl command. Its interface uses vim-style navigation, with fields that can open in the system editor. Users can apply custom UI skins, and a separate repository provides premade themes. Neovim users can access it through the wireman.nvim floating-terminal integration. Installation options include Cargo, Homebrew, X-CMD, downloaded binaries, or source builds. Rust 1.70 is the minimum listed version. The project uses the MIT license, and assistance is directed through GitHub issues.

Good

  • Supports all four listed gRPC streaming styles
  • Uses server reflection with optional authentication headers
  • Autosaves request history by default
  • Exports requests as grpcurl commands
  • Offers Neovim floating-terminal integration

Watch out

  • Linux is the only listed platform
  • Requires Rust 1.70 minimum when building or installing as specified
  • Custom themes come from a separate repository
  • No free trial is listed

Who it suits

It suits Linux developers who need a terminal workflow for testing gRPC methods and managing request history. Neovim users and teams using .proto files may benefit from its integrations.

Verdict

WireMan offers broad gRPC method support in a terminal interface, with reflection, history, headers, and editor integrations. Its Linux focus and Rust requirement should fit the development environment first.
