Kreya

Kreya is a desktop API client that unifies exploration, testing, and automation for gRPC, REST, GraphQL, WebSocket, and Server-Sent Events in a single workspace. It solves the problem of tool sprawl and data privacy by storing all data locally and integrating with Git for versioning. The product targets developers and engineering teams in organizations of all sizes, especially those in regulated industries requiring privacy. It is positioned as a privacy-first alternative to cloud-based API clients like Postman, with local-first storage and CI-ready automation.
