You can run commands... sort of.

You have a terminal on your computer. You have opened it before. Maybe you have even typed cd or npm install when a tutorial told you to. But if someone asked you to navigate to a deeply nested folder, find a file by name, or pipe one command into another, you would freeze.

This is the awkward in-between that most developers get stuck in. You know the terminal exists. You know it is powerful. But you never built the muscle memory to actually use it with confidence. And now, with AI-powered CLI tools like Claude Code and Codex expecting you to work in the terminal, the gap feels bigger than ever.

Sound familiar?

  • Copy-pasting commands from Stack Overflow without understanding them
  • Feeling lost when AI tools like Claude Code or Codex drop you into a terminal
  • Googling "how to change directory" for the fifth time this month
  • Avoiding the command line entirely and clicking through GUIs instead
  • Nodding along to tutorials that say "just run this" without explaining why

Terminal Velocity is designed to fix this. Not with videos you watch and forget, but with a real terminal you type into, right here in your browser.

Built for how developers actually learn

No fluff, no filler. Just the core terminal skills you need, taught through hands-on practice.
