What does root = true do?

It tells EditorConfig to stop searching parent directories for more config files, so your repository settings win.

Do all editors support it?

JetBrains IDEs, Vim, Neovim, Xcode and many others support it natively. VS Code needs the EditorConfig for VS Code extension.

Does it replace Prettier or ESLint?

No. EditorConfig sets basic whitespace behaviour as you type; formatters still handle full code style. They work well together.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
