First off in a direct comparison of CI/CD we are just way faster. We maintain pre-built environments on our workers and split your tests between them. Because we aren't rebuilding your workers on every run we get the full use of concurrency and when we apply enough concurrency (60X is our normal plan) we can run your test suite literally in seconds. We regularly see entire test suites run 10 -12 seconds. Basically the speed of your slowest test.
The second main way brisk is better is that you can run brisk locally in place of your terminal test runner. If you run brisk in watch mode, we'll run a complete test run every time you save. This means when you a save a file in your favorite IDE, we run your entire test suite and have the results waiting for you in your terminal.
