Side by side
Granc vs grpcui
Both stand on grpc tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
Choose Granc if you want a free, self-hosted Linux CLI for gRPC calls and service inspection using JSON. Look elsewhere if you require TLS support with configurable root certificates and client identity now.

grpcui offers a browser-based way to build and inspect gRPC requests, including support for several schema sources and transport options. Its all-at-once streaming constraint matters for developers working with bidirectional streams.

Granc: what it does well
- Sends gRPC calls using JSON payloads.
- Supports unary and all three streaming RPC modes.
- Discovers schemas through reflection or a local descriptor file.
- Lists and describes services, messages, and enums.
- Provides a separate library crate for custom tooling.
What to know first
- Listed for Linux only.
- TLS support with configurable certificates and client identity is on the roadmap.
grpcui: what it does well
- Free and released under the MIT license
- Discovers schemas through reflection or proto files
- Supports mutual TLS with client certificates
- Displays response headers, messages, errors, and trailers
- Provides Go packages for embedding its UI
What to know first
- Bidirectional streams cannot be handled interactively
- Streaming requests must be constructed all at once
- Designed for gRPC APIs, not REST APIs
