About Karate
Karate is an open source test framework for API and UI testing. Teams write tests in one plain syntax, and the framework is maintained by Karate Labs.
What it does
Karate runs automated tests against REST, GraphQL and gRPC services, and it can also drive browser-based user interfaces. Tests are written as readable scripts and run from the command line, so they fit into most build pipelines. Karate Labs also offers Karate Agent, a self-hosted product that adds AI-assisted test writing and test repair on top of the framework. It works with a language model that you host yourself.
Key features
- One syntax for REST, GraphQL, gRPC and UI tests
- Runs in any CI pipeline
- Plain-language test writing with Karate Agent
- DOM-first UI tests instead of screenshot-based checks
- Self-healing test updates when the interface changes
Who it's for
QA engineers and developers who want API and UI tests in the same tool. Teams in regulated industries may prefer the self-hosted Karate Agent, since test data and models can stay inside their own network. Product owners can also read the test descriptions because they are written in plain language.
Pricing and good to know
The Karate framework is open source under the MIT license, and the code is on GitHub. Karate Agent is an enterprise product, so its terms are agreed directly with the vendor. Teams can begin with the open source framework alone and add the commercial product later if they need the AI features.
