GitStory is a visual time back machine for GitHub projects.

📆 Use the Reactive calendar to go back in time. 🌴 Check commits by day, month and year. 🔎 Scan for commits activity of a given month by clicking on the month button in the calendar. 📸 Explore "snapshots" of GitHub repositories by navigating to the exact commit. 🌍 Explore and see the beginnings of popular Open source projects.

Hope you'll like it and it will make it to the awesome list!

Thanks!
