Kreya
Kreya is a desktop API client for exploring, testing, and automating API workflows on Linux, macOS, and Windows. It works with gRPC, REST, GraphQL, WebSockets, and Server-Sent Events, and can watch or import OpenAPI specifications, GraphQL schemas, and protobufs. Testing options include scripted checks and snapshot tests; its headless CLI can run in CI/CD and generate JUnit reports. Projects are kept in structured JSON intended to support Git diffs, reviews, and versioning. Kreya can import Postman and Insomnia collections, plus HAR, cURL, gRPCurl, and grpc web curl data. A reusable authentication vault covers OAuth 2.0, OIDC, Basic, API keys, mTLS, AWS SigV4, Kerberos, NTLM, and JWT Profile. The maker says app data stays on the device, while its privacy policy says the app and CLI collect anonymized telemetry. There is a free plan; Pro is $5 a month. Secret manager integration is marked as coming soon.
