DevPulse is a free, open-source web app that visualizes any GitHub user's public activity. Type a username to see their contribution heatmap, current and longest streaks, a playful developer archetype, top projects, primary languages, and recent public activity — all from public data, with no login required.
DevPulse needs JavaScript to render the interactive report. View the source at github.com/Chemaclass/devpulse.
