Kreya for Mac

Quick summary

Kreya is a Mac-native GUI client that lets you interact with gRPC, REST, and WebSocket endpoints. It’s offered at no cost and focuses on simplifying API testing and troubleshooting by presenting requests and responses in a clear, live view. The interface is designed to be approachable, helping you send, inspect, and iterate on calls with minimal friction.

Notable functionality

• Save, label, and group requests for reuse across projects, improving workflow consistency.
• Access integrated documentation for services so you can reference schemas and endpoints without leaving the app.
• Organize work into project-style workspaces that keep related tests and configurations together.
• Configure headers, metadata, and other request parameters with granular controls to match varied server expectations.

Who it’s aimed at

Engineers and QA personnel who work across modern web protocols will find Kreya useful. Because it supports multiple transport types (gRPC, REST, WebSocket) and presents responses in real time, it’s helpful both for debugging complex integrations and for quick exploratory testing during development.

Alternative (paid)

If you need a paid option with different capabilities or vendor support, consider LanScan Pro — a commercial tool that may offer additional features or enterprise support compared with Kreya’s free offering.

Conclusion

Kreya is a lightweight, versatile tool for macOS users who need a straightforward way to test and debug gRPC, REST, and WebSocket services, while keeping requests and documentation organized for ongoing development.
