Hey Product Hunt 👋 I'm a backend dev, and I'll admit it: I've stared at 401 vs 403 too many times. Same with 502 vs 503, 301 vs 308 — the codes that come up in every code review and every interview. So I built a small quiz to drill them properly: What it does: 🎯 10 mixed questions per round — code→meaning, scenario→code, and "which class is this" 📈 Difficulty ramps from the everyday codes (200, 404, 500) up to the trivia ones (418, 451, 226) 🔥 Streak counter + a shareable rank ("HTTP Wizard" if you nail 10/10) 🔁 No repeats within a round, and round 2 serves entirely fresh codes — actually drill-able 📚 A flashcards page if you want to study first Built for: 👨‍💻 Early-career devs prepping for interviews 🎓 CS students learning HTTP for the first time Free, no signup, no tracking — runs entirely in your browser, your score is in localStorage. If you spot a confusing question or a weak distractor, please drop it in the comments. That's the most useful feedback I can get today. Thanks for taking a look 🙏

Do you give short explanations after each question or just mark it right and wrong?

Yes. Each question includes instant feedback, a brief explanation, and links to detailed error code guides when relevant.

Clean idea, this feels like the kind of thing people actually remember better than reading a cheatsheet.

Do you track which questions users most often fail (like 401 vs 403 or 429 vs 503), or is it more just for repetition practice right now?

 Thanks for the feeback.Right now it's focused on practice. The codes you miss are tracked only in your browser, so nothing is sent to a server and there's no cross user data. In the future, I'd like to use that local history to add a mode that helps you practice the codes you struggle with most.
