  • GitPoints (Development)

    Gitpoints challenges teams of developers to write better software by gamifying their daily activity.

    We analyze the activity of developers in GitHub, including the code they write and how they collaborate. We detect a big number of problems, e.g., low test coverage, no code reviews, pull requests too big, pull requests taking too long to get merged. Then we quantify those problems and propose challenges for the team to address those problems. For instance, we would tell the team to increase the test coverage of a given module by 5% in a given week. We keep them updated of their progress towards their goal and other key metrics via email and notifications.

    Developed in Q1 2014.
