GitHub PunchCard brings back the classic punch card-style commit visualization once offered by GitHub, showing when developers are active across days and hours. Just enter a repository name (e.g. sveltejs/svelte) or paste a full GitHub URL. The tool pulls data from GitHub’s public /stats/punch_card API and renders a clean, responsive heatmap.
Built with Svelte, using html2canvas and svelte-tags-input under the hood.
