Audience
Developer teams shipping AI assisted code, or in need of onboarding / ramping acceleration, and individuals who want to learn or upskill their programming abilities.
About CodeTrain
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.
