In their own words
Chiko
Chiko is a free, open-source desktop terminal interface for testing gRPC APIs. When a server exposes reflection, it can discover and browse available gRPC endpoints. Chiko creates formatted request templates, and requests can include Bearer-token authorization, custom headers, and other metadata. You can save requests as bookmarks and replay them later. The project lists importing and exporting grpcurl commands as completed features, and a release changelog records SSL connection support. Installation instructions cover Homebrew, Go installation, building from source, and prebuilt releases. Chiko is licensed under the MIT License and lists a Free plan at free, with no paid plans or usage limits stated. OAuth, API keys, proto-file import, and password protection for sensitive bookmarks are listed as work in progress. Felix Angga, identified as a software engineer, is the maker.
