Coding courses and project-based learning paths for beginners
Learn how web apps work while building with an AI coding agent

Open Vibe is a free, open-source learning workflow that turns an AI coding agent into a guide for building web applications. Its instructions, skills, and interactive components help users develop their own app while learning what happens behind the interface. Diagrams can explain how the browser, server, and database connect within the project being built.
The course offers a starting path for web-app basics and a second path using the Open SaaS template, which includes common SaaS infrastructure. Users work locally with a capable agent such as Claude Code or Codex and can ask questions as they progress. Modules are released incrementally, with availability shown on the course page.
