Devmaxx vs Bugged

System design is becoming one of the most important skills for software engineers. Many companies now require a dedicated system design interview, and your career growth often depends on your ability to design large-scale systems. Devmaxx gives you one focused system design question every day across databases, infrastructure, APIs, theory, and product to help you learn these skills and stay sharp. Each question takes about two minutes, and includes a resource to learn more about the subject. What you’ll get:
 • A new system design question daily
 • Clear explanations for every answer
 • Breakdown of the correct answer
 • Access to previous questions
 • Linked resources to go deeper
 • Access to a private community of developers learning and building the same things as you • Progress tracking to monitor growth • Join your friends in pods and battle against other pods while learning system design. If you’re preparing for interviews, this builds daily momentum. If you’re already working as an engineer, this keeps your fundamentals sharp. Open the app. Answer one question.

One bug a day, hiding in code that looks fine. Every day a short piece of real-world code appears with a bug in it. Read it, tap the line you think is wrong, and find out. Three guesses, clock running. Harder days hide two or three bugs and tell you how many. Find it and you get a grid worth sharing, a place on the day's leaderboard, and the part that actually teaches: how the bug got in, and how a reviewer would have caught it. THE DAILY IS FREE. No account needed to play. Sign in to keep your streak, your language, and your place on the board. PICK YOUR LANGUAGE. Most puzzles come in Java, TypeScript, Python, Go and C#. Play the one you work in, or the one you are learning. REAL BUGS, NOT BRAIN TEASERS. Off-by-ones, races, time zones, null handling, injection, resource leaks, retry storms, misconfigured containers. The kind that ships on a Friday and pages you on Saturday. Some come straight from open-source fixes, with credit. A REAL BROKEN BOX. Pro opens live sandboxes: an actual Linux container with a terminal and an editor, a service that is genuinely down, and a checker that decides when you have fixed it. Thirty minutes on the clock. The Weekly Boss drops every Monday and is a bigger one. TRAINING FOR THE ROUNDS THAT COUNT. Interview loops test code review and debugging, and so does the job. Every puzzle drills the same habit: read fast, form a hypothesis, commit under a clock, explain the fix. Puzzles are labeled easy, medium and hard, and the week climbs from Monday to Friday. WATCH YOURSELF IMPROVE. Streaks, a rating that moves with how you solve, badges, and a profile showing the languages you are strongest in. BUGGED PRO adds the archive of every past Daily, tracks that climb from easy to hard in one language or bug class, an unlimited practice queue, hints, streak freezes, timed five-puzzle mock sessions, every theme, and the sandbox gym. Bugged Pro is an auto-renewing subscription, monthly or yearly, billed to your Apple ID. It renews unless cancelled at least 24 hours before the end of the period.
