Measured open-source projects

2,154 open-source projects, measured. Every one was assessed against the Codebase Assurance Index at a pinned commit — the same rubric, applied the same way, to all of them. The index is an open standard, so any of these numbers can be recomputed from the evidence behind it. Each language below is shown as the spread of its projects' scores rather than one number, next to how deep the survey of them reached — because a score means one thing when the survey resolved a dozen dimensions and another when it resolved two dozen.
