ECGithub - Contribution Graph Heartbeat

Transform your GitHub contribution graph into an ECG heartbeat visualization

Transform your GitHub contribution graph into a heartbeat. ECGithub replaces the standard contribution heatmap on GitHub profile pages with a real-time ECG (electrocardiogram) waveform visualization. More contributions = taller heartbeat peaks. FEATURES • ECG heartbeat waveform — your contributions visualized as QRS+T peaks • 5 color themes + custom color picker • Stats panel — total, best day, average, streaks • 3 view modes — Normal / ECG / Both • PNG export — save and share your heartbeat • Light & dark mode support • Zero external dependencies HOW IT WORKS The extension reads your GitHub contribution data and converts it into SVG paths using a waveform algorithm inspired by real ECG signals. No data is collected or sent anywhere — everything runs locally in your browser. PERMISSIONS • Storage — saves your theme preferences • github.com — reads contribution graph data (no other sites) Open source: https://github.com/theorakim/ecgithub
