What Mocki is
Mocki helps developers create, run, and deploy mock APIs for software development and testing. Its mocks can return fixed responses or simulate errors, delays, and conditional behavior, supporting work such as frontend and backend development, integration testing, and microservice testing. You can define a service in YAML or use the web interface, and generate realistic test data with a YAML configuration. A free API editor turns a response body into a custom API URL. For local work, the Mocki CLI runs services offline as well as online and is installed from npm. Managed hosting is available, with repository synchronization and a GitHub integration that updates hosted mocks when repository changes occur. Projects can be shared by signing in with GitHub, and members of a GitHub organization can access configured projects. Mocki supports REST and GraphQL and offers web, API, and self-hosted use. A free plan and a 7-day trial are available. Starter costs $15 a month and includes 1,000 requests per day, prioritized support, and a monitoring dashboard.
