Kreya: sovereignty score and 8 European alternatives

Kreya is a desktop application for exploring, testing and automating APIs, with support for gRPC, REST, GraphQL, WebSocket and Server-Sent Events. It is aimed at developers and testers who work with gRPC services and want to write scripted or snapshot tests that also run headless in a continuous integration pipeline. Requests and collections are stored as files that can be versioned in Git. The product is installed on the user's computer and is not offered as a hosted service.

Kreya is developed by riok GmbH, a Swiss company with its registered seat in Gossau in the canton of St. Gallen. According to the vendor, everything stays on the user's device, and core use does not require a cloud account. The source code is on GitHub, but the licence is not named on the website, so it cannot be described as open-source software. The website does not mention a data processing agreement; a European organisation that needs one can request it directly from the vendor.

Why digital sovereignty matters with Kreya

Kreya is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Kreya runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

Kreya is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Kreya together with your other vendors and gives a total score, a heatmap and the main risk drivers.
