In their own words
Karate
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.
Zally
Zally is an API linter and quality assurance tool for OpenAPI specifications. It supports OpenAPI 3 and Swagger OpenAPI 2, with a RESTful API, command-line interface, and web interface. Its standard configuration checks APIs against Zalando’s RESTful Guidelines, and the project says it can also be used out of the box by others. Teams can enable or disable server-side rules, configure some existing rules, or implement their own in Kotlin. An API definition can use the x-zally-ignore extension to disable rules for that API. The web interface lists implemented rules and can lint external files and API definitions in its online editor. The project describes starting the web UI, server, and database together using Docker Compose. It also lists an unofficial Zally Maven Plugin integration. Maintained by Zalando, Zally is offered under an MIT license with an exception. Its Open source plan costs nothing.
