In their own words
Concordion
Concordion is a free, open-source tool for turning written specifications into executable checks and living documentation. Those checks run against the system under test; when they run, Concordion generates documentation that marks passing and failing assertions and shows expected and actual values for failures. The output can include tables and links to other specifications. The project offers Java specifications in Markdown or HTML, along with C# options. Java fixtures use JUnit, and Concordion.NET is documented with NUnit. Integrations include IntelliJ IDEA, Eclipse, Gradle, Maven, command-line execution, Jenkins, and Spring. The IntelliJ plugin supports HTML and Markdown, while Eclipse supports HTML specifications but not Markdown. Extensions can add commands, event listeners, or documentation changes, with examples such as Excel specifications, parallel runs, screenshots, and logging tools. Concordion runs locally on Linux, macOS, and Windows, and is licensed under Apache License 2.0. It is maintained by volunteers.
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.
