tldr: GitHub’s built-in repo analytics sucks, so I built a better oneAs a maintainer of a few open-source projects, I’ve always wanted to better understand the traffic sources and trends for my repos. Unfortunately, GitHub’s built-in analytics only show limited data from the past 14 days, which doesn’t provide much insight.That’s why I built Repohistory, a better GitHub repo analytics platform. It automatically fetches and stores your traffic data every day, so you’re no longer limited to just 14 days. The dashboard shows you:Daily star growthTotal views & clones over timeTop referral websitesMost-viewed pages in your repoSo if you have any public repos on GitHub, Repohistory can give you a much clearer picture of your traffic trends!
