What is Kreya?
Kreya is a unified API client designed for developers to debug and interact with various API types including gRPC, REST, Server-Sent Events (SSE), and WebSockets from a single workspace. It supports modern protocols like HTTP/1.1, HTTP/2, and HTTP/3, and offers flexible transport options including HTTP, Unix domain sockets, and Windows named pipes.
This tool is ideal for individual developers and teams working with diverse API ecosystems, especially those in regulated industries due to its privacy-first architecture where all data remains on the user's device. Kreya streamlines API development and testing by allowing users to sync API definitions from OpenAPI specs and protobufs, automate workflows with JavaScript scripting, and perform snapshot tests to detect regressions. It also facilitates collaboration through Git-native project sharing and offers seamless migration from existing tools like Postman and Insomnia.
