17 progressive units per language. Lessons, exercises, quizzes, unit tests, and capstone projects.
Every run earns progress. Daily streaks and unlockable badges keep you coming back.
Teachers create classes, assign auto-graded work, and watch progress in real time. Grades export to CSV.
Monaco, the engine inside VS Code. Syntax highlighting, autocomplete, and instant feedback on every run.

Stop grading code by hand. Stop chasing down who turned in what. Learnix gives teachers a full classroom with auto-graded assignments and real-time progress.
Forget passive tutorials. Every lesson hands you a real problem and the editor to solve it in. Earn XP, build streaks, unlock badges.
Every project records itself. Scrub through any submission keystroke-by-keystroke - see the student who clearly built it, or the 400 characters that appeared in one paste at 2am. Proof, not a guess.
Kahoot, but for real code. Launch a timed challenge and students join at learnix.academy/join with a 6-character code - no account needed, guests welcome. They race to solve it in the browser and a live leaderboard ranks who lands it fastest.
I went from "what's a variable" to writing my own bank-account class in three weeks. The exercises after every lesson are what finally made it stick.
My AP Computer Science class moved to Learnix mid-year. Auto-grading saved me hours every week, and my pass rate went up. The classroom dashboard is everything I wanted from Codecademy and never got.
No installs, no setup, no "your version of Java is wrong". I clicked Run and it ran. That alone was worth the switch.
The Python curriculum is the most modern one I've seen - comprehensions, dataclasses, type hints, generators all covered properly. Not another "let's print Hello World 30 times" course.
The streaks got me hooked. 47 days in and I'm building real projects now. Best decision I made this year.
CodeHS, Codecademy, Replit, and the rest are good at what they do. Here is the honest breakdown of where Learnix is the better call — and where it isn't.
Free to start, and deeper on Java & Python than a broad multi-language catalog.
