WebTerm is a browser-based terminal sandbox designed specifically for learning command line interface (CLI) operations in a safe environment. It provides an ephemeral, no-signup, free platform where beginners can practice Linux commands without worrying about damaging their local system.

The platform offers multiple learning modes including Getting Started for learning input methods and key operations, Beginner mode for basic commands, Fundamentals for commonly used commands, and Advanced mode for commands used in specific situations. It also includes dedicated Git sections covering Git basics, branching, history operations, and explanations of Git's role and benefits. Users can navigate using keyboard shortcuts (↑↓j/kCtrl+p/n) and select modes using Enter or number keys 1-8.

WebTerm works by providing a simulated terminal environment directly in the web browser, eliminating the need for local installations or configurations. The interface is designed to be accessible with keyboard-only navigation since mouse input is not available in the terminal simulation.

The primary benefit is providing a risk-free learning environment where users can experiment with terminal commands without consequences. It's particularly valuable for beginners who are afraid to open their local terminal due to concerns about breaking something. The platform supports learning file operations, Git workflows, and CLI-based AI tools.

WebTerm targets beginners learning programming and command line operations, including both engineers and non-engineers who need CLI literacy in the AI era. The platform is currently in beta and welcomes user feedback.
