CodeLingo
Duolingo-style gamified coding lessons.
Live demo coming soon
CodeLingo is a full Next.js 16 application (not a single static page), so it gets its own deployment — going live shortly.
About this project
A Duolingo-inspired platform for learning to code through bite-sized, gamified lessons — a winding skill tree, split-pane lessons, and XP / levels / hearts / streaks. Its standout is an in-browser JavaScript judge that runs your code in a sandboxed Web Worker. Built in Next.js + React.
