Instead of Kreya
Kreya alternatives
Kreya is a desktop client for exploring, testing, and automating API workflows on Linux, macOS, and Windows. It covers gRPC, REST, GraphQL, WebSockets, and Server-Sent Events, imports specifications and collections, and provides reusable authentication for several schemes. Scripted tests, snapshot tests, JUnit-producing CLI runs, and Git-friendly JSON projects support automated and versioned work. The free plan costs $0 and limits request history to the latest request; Pro costs $5/user/month. Kreya has no mock server, is not open source, and secret-manager integration is coming soon.

An alternative may fit better if you need browser access, self-hosting, service mocking, or a different collaboration model. Compare whether each product supports your protocols and preferred design, testing, debugging, or documentation workflow. Check how collections, environments, scripts, and team access work, and whether the available CLI or CI/CD integration matches your process. Pricing also matters: some options charge per user, while others are free. The choices below include broad API platforms, open-source testing tools, Git-oriented clients, a command-line-focused option, and collaborative web software.
