BloomRPC Extended vs Evans

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.

Evans is a free universal gRPC client for manual API inspection and scripting on Linux, macOS, and Windows. Its interactive REPL completes package, service, and RPC names. Stateless CLI mode reads standard input or files and prints JSON-formatted results. When server reflection is enabled, Evans can use that instead of proto files. It supports client-streaming, server-streaming, and bidirectional-streaming RPCs, plus gRPC-Web; TLS is not supported for gRPC-Web. The listed IDL and codec is Protocol Buffers 3, and the compressor is GZIP. For ordinary gRPC connections, the project documents secure TLS connections with the --tls option. Installation options include GitHub Releases, Homebrew, Docker, and Go, with Releases or Homebrew recommended for automatic updates. The documented Go installation requires Go v1.20 or later. The repeat option does not support client-streaming or bidirectional-streaming RPCs. Evans uses the MIT license.
