Overview

Mockoon designs and runs mock REST APIs locally from a desktop application, with no account or remote deployment needed. Mocks can be built from OpenAPI specifications and use dynamic templating, rules matching, JSON databases, proxy mode, webhooks and TLS, then run headless via the CLI, Docker image or serverless package. Mockoon Cloud adds hosted mocks, sync and real-time collaboration.

Best for: Developers and small teams needing local mock REST APIs for development and integration testing
Pricing: The desktop app, CLI and serverless package are free and open-source; Mockoon Cloud's Team plan is $100/month billed annually, and Enterprise is priced on request.
Runs on: WebmacOSWindowsLinuxSelf-hostedCLI
