MessyDev
Teaches you to debug and understand the code your AI coding tool just wrote.
MessyDev is an interactive course that walks you through why AI-built code breaks — bad auth, wrong API shapes, missing env vars, failed deploys — instead of just handing you more code. It has 8 chapters, 31 lessons and 76 hands-on exercises covering topics like databases, permissions, and GitHub. The first exercise is free with no account required; full access is $9/month.
What holds up
- +First exercise is free with no account needed — try it before paying anything.
- +76 hands-on exercises cover real failures: broken auth, bad API shapes, dead deploys.
- +Works alongside tools you already use — Lovable, Claude, ChatGPT, Cursor — not a replacement.
Mind the limits
- −$9/month subscription for the full 8 chapters and 31 lessons — no one-time price.
- −Teaches you to debug AI-built code — it won't fix that code for you.
