BloomRPC Extended vs gRPC Swagger

BloomRPC Extended is a free desktop GUI client for exploring and querying gRPC services on Linux, macOS, and Windows. It is a maintained fork of the original BloomRPC, which the project says was archived in January 2023. Native calls include unary, server streaming, client streaming, and bidirectional modes; gRPC-Web and server reflection are also supported. Users can import and manage .proto files, manage environments, and edit metadata. TLS and SSL connection security are available. The interface provides draggable service tabs, search and filtering, grouping by service, an overflow menu, and a close-all control. Packaged builds use CodeMirror 6 for syntax highlighting, according to the project. Downloads include macOS DMG, Windows EXE, and Linux AppImage or DEB. Homebrew and Scoop installation instructions are listed for macOS and Windows. GitHub Issues is the reported support route. The repository lists LGPL-3.0-or-later licensing; source builds require Bun v1.0 or later.

gRPC Swagger is a free, open-source debugging tool for discovering and calling gRPC methods through Swagger UI. It uses server reflection to scan a registered endpoint, identified by host and port, and then displays available services, method definitions, and parameters. Users can invoke methods with Swagger UI’s “Try it out” control, supplying request data and headers as JSON; the headers are passed to the gRPC server as metadata. Reflection must be enabled on the gRPC service, but the setup instructions say proto files and related implementations do not need modification. The project runs from a released JAR or from source and defaults to port 8080. Configuration can show registered services and expire inactive registrations after a chosen number of seconds. Documented endpoints cover registration, service listing, method calls, and Swagger documentation. It is self-hosted, available for API and web use, and licensed under MIT.
