Coveralls.io: Deliver Better Code

We help you deliver code confidently by showing which parts of your code aren’t covered by your test suite.

Eliminate Tech Debt

Maintaining a well-tested codebase is mission-critical, but figuring out where your tests are lacking can be painful. You're already running your tests on a continuous integration server, let it do the heavy lifting. Coveralls works with your CI to sift through coverage data to find gaps you didn't know you had.

Percy gives your team confidence in every visual UI change before it's shipped.

Percy adds visual reviews to your GitHub pull requests, helping your team spot UI bugs quickly and review visual changes easily.
