What it is
Karate is a testing framework that combines API, UI, mock, and performance testing with readable syntax. Its free MIT-licensed core supports REST, GraphQL, and SOAP testing, including JSON and XML assertions and schema validation. It can automate browsers and desktop apps, and teams can combine UI and API steps in one test. Built-in Gatling integration allows API tests to be reused for performance testing. Listed integrations include AWS, Google Cloud, Azure, Jenkins, GitHub Actions, Maven, Gradle, Docker, IntelliJ, VS Code, and Gatling. The free plan costs nothing and includes community support. Paid options include IDE Plus at $100 a year, Xplorer Premium at $200 a year, and Pro at $640 a year. Pro adds IDE plugins, debugging and step-through, enhanced autocomplete, development-stage async protocol testing, and priority email support. Kafka, gRPC, and WebSocket testing belong to the enterprise async protocol offering; production CI/CD execution for it requires an Enterprise runtime license. Karate Labs says its products run locally or in customer infrastructure, store no customer test data, and ship with zero telemetry.
