A real price — calculated from your <br> actual activity. Followers, stars, repos, and most <br> importantly: what you shipped THIS week.</p> <p>That's GitBull.</p> <h2> How the price works </h2> <p>Every developer gets a price based on two things:</p> <p><strong>BASE</strong> — your standing:</p> <ul> <li>Total followers</li> <li>Total stars across all repos </li> <li>Number of public repos</li> </ul> <p><strong>MOMENTUM</strong> — what you did this week:</p> <ul> <li>New commits</li> <li>New stars gained</li> <li>New followers</li> </ul> <p>Ship more code = price goes up 🟢<br> Go quiet = price drifts down 🔴</p> <p>Prices update every Monday via a weekly cron job.</p> <h2> What I built in 4 days </h2> <ul> <li>FastAPI backend with GitHub GraphQL API</li> <li>10,000 developers pre-populated in Firebase</li> <li>Flutter Web frontend</li> <li>3D candlestick market in Three.js (10k devs rendered live)</li> <li>Buy/sell with virtual points, portfolio, leaderboard</li> <li>Weekly cron that refreshes all dev prices</li> <li>Share your price card to Twitter/LinkedIn</li> </ul> <h2> The interesting part — week 1 data </h2> <p>After the first Monday cron ran, some devs jumped massively:</p> <ul> <li>DietrichGebert: $38,627 ▲4427% (was shipping hard)</li> <li>Matt Pocock: $19,448 ▲3235%</li> <li>Torvalds: $3,003 ▲334%</li> </ul> <p>The formula actually works — active devs rise, quiet ones fall.</p> <h2> Tech stack </h2> <ul> <li> <strong>Backend:</strong> FastAPI + Firebase Firestore</li> </ul> <p>@github @buildinpublic <a class="mentioned-user" href="https://dev.to/webdev">@webdev</a></p> backend flutter github showdev
