Grapity vs Karate

Grapity is an open-source API governance platform for teams coordinating API contracts and their consumers. Its Registry compares each pushed specification with the previous version and blocks breaking changes with an explanation. It enforces semantic version increments and tracks deprecation lifecycles, including consumers and sunset dates. The Hub offers a searchable API list, endpoint exploration, side-by-side version comparisons, and a version timeline. Grapity governs OpenAPI and AsyncAPI formats, with CI/CD integration and role-based access control. For Kong, Grapity Gateway generates configuration from registered specifications, and the CLI provisions it through decK; Kong can also send access logs to the Registry using its http-log plugin for queries and traffic statistics. The project says it is licensed under Apache 2.0 and has no features locked behind paywalls. Self-hosted use costs nothing, billed forever, with unlimited APIs and team members. Cloud costs $29.95 a month and includes five APIs and five users.

Karate is a testing framework for API, UI, mock, and performance work. Its MIT-licensed core is free for commercial projects and supports REST, GraphQL, and SOAP testing, with JSON and XML assertions and schema validation. It can automate browsers and desktop apps, and combine UI and API steps in one test. Built-in Gatling integration lets teams reuse API tests for performance testing. The Free plan costs nothing and includes community support. Paid plans include IDE Plus at $100 a year, Xplorer Premium at $200 a year, and Pro at $640 a year; Pro adds IDE plugins, debugging, enhanced autocomplete, development async protocol testing, and priority email support. The platform lists integrations including AWS, Google Cloud, Azure, Jenkins, GitHub Actions, Maven, Gradle, Docker, IntelliJ, VS Code, and Gatling. Enterprise async protocol testing covers Kafka, gRPC, and WebSocket, but production CI/CD execution requires an Enterprise runtime license. Platforms include API, extension, Linux, macOS, self-hosted, and Windows.
