Designercize is a free design challenge generator that helps UX, UI, and product designers sharpen their problem-solving and whiteboarding skills through short, timed exercises.
Instead of browsing portfolios or reading design theory, users receive randomized design prompts in a simple “Design / For / To help” format, choose a difficulty level, set a timer, and begin solving realistic product design challenges.
The platform is particularly valuable for interview preparation, daily design practice, portfolio warm-ups, and improving design thinking under time constraints. Tradecraft instructors Zac Halbert and Jake Fleming created it, and it has become a popular resource for designers preparing for whiteboard interviews.
The website embraces a playful yet highly functional design with a clean interface that eliminates distractions and keeps the focus on practice. Users can instantly generate new prompts, select Easy, Medium, or Hard challenges, customize session durations, and launch a built-in countdown timer.
The minimalist layout, retro-inspired visuals, and intuitive interactions make it easy to jump into focused design sessions, encouraging consistent skill development rather than passive learning.
