About:
Kreya is a cross-platform GUI client designed for interacting with gRPC, REST, and WebSocket services. It provides an intuitive interface for testing APIs, managing requests, and visualizing responses. The tool streamlines API development workflows by consolidating multiple protocols into a single application.
Key Features:
  • Multi-protocol support (gRPC, REST, WebSocket)
  • Cross-platform availability (Windows, macOS, Linux)
  • Intuitive user interface for request management
  • Environment variable support for dynamic configurations
Use Cases:
  • Testing and debugging gRPC services during development
  • Consuming REST APIs with organized request collections
  • Real-time communication testing with WebSocket endpoints
Alternatives:
  • Postman – Postman focuses on REST APIs while Kreya specializes in gRPC alongside REST and WebSocket support
  • BloomRPC – BloomRPC is gRPC-only; Kreya offers broader protocol support and a more modern interface
  • Insomnia – Insomnia is primarily REST-focused; Kreya provides native gRPC protocol handling
