Making coding
accessible
to everyone.
We believe everyone should have the opportunity to learn programming—regardless of background or budget.
That's why we built a platform that's completely free, requires no sign-up, and focuses on what actually works: deliberate practice.
Simple, effective
learning.
Read the code
Each exercise presents real code with strategically placed blanks. See context and structure, understanding how pieces fit together.
Fill the blanks
Select the correct option to complete each blank. Pattern recognition and recall—no typing required. Immediate feedback accelerates learning.
Build fluency
Repetition makes syntax second nature. Track progress, build streaks, and watch your coding fluency grow with every session.
Why we're
different.
Free Forever
No paywalls, no premium tiers, no hidden costs. Quality education should be accessible to everyone, period.
No Sign-Up Required
Start learning immediately. No registration forms, no email verification, no waiting. Just pure, focused practice.
Interactive Learning
Active practice beats passive watching. Our fill-in-the-blank format keeps you engaged and builds muscle memory.
Multiple Languages
From JavaScript to Python, Java to TypeScript—learn the languages that matter most in today's tech landscape.
Built by developers,
for learners.
We're a team of developers who've been through the struggle of learning to code. We know what works and what doesn't.
Our mission is simple: make coding education accessible, effective, and free for everyone. No gimmicks, no gatekeeping—just quality practice that builds real skills.
