About

CodeTrain is a training tool for engineers who ship with AI and can no longer explain everything they shipped. It takes a question, a repo, or an onboarding task and turns it into a short lesson of two to six steps against the real code. The learner types every line. The tutor plans the steps, runs the code, grades each attempt, and makes the step smaller when someone is stuck instead of handing over the answer outright. The free tier executes Python in the browser through Pyodide, so nothing leaves the machine and the tier costs almost nothing to run. Server-side sandboxes handle the shell and toolchain lessons. The control plane is FastAPI on Fly.io, the front end is static on Cloudflare Pages, auth is Clerk, billing is Stripe. Tutoring runs on Claude models by default, and bring-your-own-key is supported for Anthropic, Bedrock, Vertex, OpenAI-compatible endpoints, and Ollama, so a team can keep inference on infrastructure it already owns.

About

Codédex is an online, interactive coding-learning platform that uses a gamified, adventure-style format to teach real programming languages and skills. Learners travel through “fantasy lands” corresponding to languages such as Python, HTML/CSS, JavaScript, React, and command-line tools (Git, GitHub), proceeding at their own pace while earning experience points, badges, and unlocking new regions as they progress. It combines bite-sized interactive lessons, an in-browser code editor for instant practice, and project-based tutorials to give users hands-on experience rather than just theory. With more than 200 hours of content, Codédex supports beginners with no prior coding experience and gradually builds up to more advanced topics, reinforcing learning through code challenges, exercises, and real-world projects. It fosters a supportive community through forums and events like monthly challenges and hackathons, helping motivate learners and provide peer support.
