Introduction

Kreya is a desktop client for exploring, testing and automating APIs. Its site says it offers native tooling for gRPC, REST, GraphQL, WebSocket and Server-Sent Events, which makes it particularly popular with teams that work heavily with gRPC.

Requests and projects are stored as files that can be shared, reviewed and versioned with Git, without a SaaS account. Kreya supports automated tests with snapshots and scripts and CI-ready workflows, according to its homepage.

Kreya positions itself as privacy-first: data stays local by default. A free-forever plan covers individuals, with Pro and Enterprise plans for advanced features and companies.

In the quality loop it supports API exploration and scripted checks, especially for gRPC services.

Features

  1. Multi-protocol: gRPC, REST, GraphQL, WebSocket and SSE.
  2. Snapshot tests: Compare responses against stored snapshots.
  3. Scripting: Scripts for setup and assertions.
  4. Git-friendly: Projects stored as files for version control.
  5. CI workflows: Run collections in pipelines (paid features may apply).

Pros

  1. Strong gRPC support: Native gRPC tooling with reflection and protos.
  2. Local-first: No mandatory cloud account.

Cons

  1. Advanced features paid: Some testing and CLI features need Pro or Enterprise.
  2. Closed source: Proprietary desktop app.
  1. Create a project and import proto files or use server reflection.
