Wombat

Wombat provides a graphical interface for interacting with gRPC services on macOS, Linux, and Windows. It reads `.proto` files, discovers services and methods, and builds request messages for scalar, nested, enum, repeated, oneof, and map fields, allowing users to configure TLS or use plain‑text connections. The client supports all RPC patterns—unary, server streaming, client streaming, and bidirectional streaming—and can add metadata, cancel in‑flight requests, and send EOF for streaming calls.

Responses are displayed with full header and trailer information, and the tool shows detailed RPC statistics. It also leverages the gRPC reflection API to determine schemas at runtime and includes support for Google Well Known Types. Users can organize workspaces and switch between them, making it easier to manage multiple projects.

Wombat is distributed as native binaries and can be installed via Homebrew on macOS, AUR on Arch Linux, or by downloading the appropriate archive for each platform. The software is marked as stable and is listed among curated gRPC resources.
