IBM Rational Functional Tester vs TestCafe

IBM Rational Functional Tester has no write-up on Specifiction yet; its figures are above.

TestCafe is a free, open-source test runner and end-to-end framework for web testing. Tests can be written in JavaScript or TypeScript, or recorded in a browser with TestCafe Studio. The runner works in modern browsers locally or remotely and supports concurrent runs across browsers. It can also switch between iframes and multiple browser windows to cover interactions across those contexts.

The framework includes server-side API testing tools for standalone API tests or functional tests. Other capabilities include automated waiting, authentication roles, hooks, request mocking, and debugging mode. Its CI guide lists services including GitHub Actions, GitLab, Jenkins, Azure DevOps, and CircleCI, plus BrowserStack, LambdaTest, and Sauce Labs. Installation is available through npm, with a Docker image for CI/CD pipelines. After each run, TestCafe says it deletes browser cookies, clears storage, and reloads the page; parallel runs use separate sandboxed environments. The framework is MIT-licensed. Paid Dashboard plans have test-run quotas, but those do not limit the open-source runner.
