What is TerminalVEX?

TerminalVEX is a free, AI-powered platform that teaches you how to use the terminal (command line) — from your very first command to advanced DevOps workflows.

Why Learn the Terminal?

  • The terminal is the foundation of software development, system administration, and DevOps.
  • It gives you direct, powerful control over your computer that GUIs can't match.
  • Almost every developer job requires terminal skills — from Git to deployment.
  • Automation, scripting, and server management all happen in the terminal.
  • AI CLI tools like Claude Code, GitHub Copilot CLI, and Cursor run in the terminal — understanding the terminal lets you know what these tools are actually doing.

What Makes TerminalVEX Different?

Virtual Terminal in Browser

No setup needed. Practice commands directly in a simulated terminal that runs in your browser. Safe — nothing touches your real system.

AI Teacher

An AI guides you through each lesson, gives tasks, checks your work, and provides instant contextual feedback. It adapts to your pace.

Science-Based Learning

Quizzes every 5 commands and challenges every 10 commands reinforce learning through active recall and spaced practice.

70 Structured Lessons

From pwd and ls to Docker, Git, and CI/CD. A complete curriculum that takes you from absolute beginner to power user.

Your Data Stays on Your Device

All progress, settings, and API keys are stored in your browser's localStorage. Nothing is ever sent to our servers.

Bring Your Own AI

Choose from Claude, OpenAI, Gemini, Groq (free), or OpenRouter. Use your own API key.
