About CodeTrain

CodeTrain is a Socratic AI coding tutor: it asks questions, reviews what you write, and runs your tests, but never writes the code for you. Free to start. Two steps, about a minute, and the first one is going to catch you. The tutor's replies are pre-recorded, so it knows the handful of ways this lesson usually goes wrong. The real one reads whatever you actually wrote, and it is free for ten lessons a month.

About One

Build an open source ecommerce store without writing code. One-click GitHub starter, Codespaces, and Claude, for learning, prototyping, and building on Magento® or Mage-OS. Not a hosted SaaS. Are a developer who wants Magento ® + Daffodil ready to code against in your browser, with no composer, nginx, or MariaDB to configure. Are curious how a real ecommerce stack works and want to learn by building and tinkering. This is a brand-new starter, not a migration tool.
