# File Uploader Documentation

upup is a file uploader with a native UI for **React, Vue, Svelte, Angular,
Vanilla JS, and Preact**, built on a shared headless core (`@useupup/core`), with
an optional server mode for signed uploads and cloud-drive sources (Google
Drive, OneDrive, Dropbox, and Box). Every package renders the same UI.
