Hey Product Hunt! 👋 I'm Gabriel, the maker of SpeedQL. Most ways to learn SQL are passive: you watch a tutorial, read a chapter, tick a multiple-choice box. But SQL only really sticks when you write queries yourself, get them wrong, and fix them fast. So I built a game around exactly that. How it works: you get real tables, a short task, and 1 minute on the clock. Write the query, hit Ctrl + Enter, and if your result matches, you gain 30 seconds. Every 3 correct answers you level up, from a plain SELECT all the way to JOINs, CTEs and window functions. Your query is also checked against a hidden dataset, so hard-coding the answer doesn't work 😉 Not a fan of pressure? There are other ways to play: 🗺️ Learning path: 12 steps, no timer, for complete beginners 🎯 Custom exercises: pick the topics you want to drill, with hints 📅 Daily exercise: one question a day, the same for everyone, keep your streak alive A few things I cared about: • 100% free, no account, no ads • The SQL engine (SQLite) runs entirely in your browser, and nothing is sent to a server • 416 hand-written questions + 100 templates for endless practice • A retro desktop look, because learning should feel a bit like playing • Available in English, French and German I'd love your feedback, especially: Does the difficulty curve feel right? What SQL topic or mode would you like to see next? Drop your best score in the comments, and I'll be here all day to answer questions!
