What Karate is
Karate is an MIT-licensed test framework that covers REST, GraphQL and SOAP API testing, built-in mocks and performance testing through Gatling. Karate Labs sells IDE plugins, Xplorer Premium and an Enterprise edition with async protocol support (Kafka, gRPC, WebSocket) and API coverage reporting.
Pros and cons
- Core framework is free and MIT-licensed, including mocks, Gatling performance tests and CI/CD use
- One framework covers API, UI and performance tests
- Paid tiers are listed per user with public prices
- Async protocols (Kafka, gRPC, WebSocket) in CI/CD need an Enterprise runtime license
- Tests are written in Karate's own DSL, so non-coders need the IDE or Xplorer tooling
- Enterprise trials require a vetted, scoped request rather than self-serve sign-up
