“Codecov unifies coverage data in one place and visualizes the data very well. It also provides the API to query the data for analytics purposes. For our usage, it provides the feedback on pull requests directly and nicely improves the developer experience to shorten the feedback loop so that they can fix their issues more quickly.”
