Facts checked 8 Oct 2026

In short

The Free plan has no price and covers gRPC, REST, GraphQL and WebSocket, with server-sent events handled inside REST requests^1,6.
Pro costs $50 a year ($4.17 a month) and adds scripting, tests and collections¹.
Projects are stored in git-diffable files in a folder you choose^2,10.
Apps run on macOS, Windows and Linux; no web app is listed².
Kreya is not open source³.

Kreya suits developers who want gRPC, REST and GraphQL in one desktop client with projects kept as plain files^1,2. The free plan includes the gRPC, REST, GraphQL and WebSocket clients and the CLI¹, and projects are Git-friendly files². The catch: scripting, tests and collections need Pro, there is no web app, and the source is closed^1,2,3.

Best for: Developers who work with gRPC and want local, file-based projects.
