BloomRPC Extended vs Kreya

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.

Kreya is a desktop API client for exploring, testing, and automating API workflows on Linux, macOS, and Windows. It works with gRPC, REST, GraphQL, WebSockets, and Server-Sent Events, and can watch or import OpenAPI specifications, GraphQL schemas, and protobufs. Testing options include scripted checks and snapshot tests; its headless CLI can run in CI/CD and generate JUnit reports. Projects are kept in structured JSON intended to support Git diffs, reviews, and versioning. Kreya can import Postman and Insomnia collections, plus HAR, cURL, gRPCurl, and grpc web curl data. A reusable authentication vault covers OAuth 2.0, OIDC, Basic, API keys, mTLS, AWS SigV4, Kerberos, NTLM, and JWT Profile. The maker says app data stays on the device, while its privacy policy says the app and CLI collect anonymized telemetry. There is a free plan; Pro is $5 a month. Secret manager integration is marked as coming soon.
