About Uguu

Uguu is a simple, lightweight platform for temporary file hosting and sharing that can also serve as a permanent file host. Uploading takes one click and needs no registration, and the web interface is minimal and modern, supporting drag and drop, paste and click-to-select. It is aimed at anyone who wants to run their own quick-share service, and a public instance runs at uguu.se.

An upload API can return responses in JSON, HTML, plain text or CSV, and the service works with ShareX and other screenshot tools. Administrators can restrict files by extension or MIME type with black or whitelists, apply upload rate limiting, and blacklist files by hash. The README lists tested requirements of Nginx with PHP 8.3 and SQLite, MySQL or PostgreSQL; Bun is used to compile front-end assets before the app runs on PHP.

Installation and configuration are covered in the project documentation. Uguu is based on the earlier Pomf project, follows the PSR-12 coding standard enforced with PHPCS, and is licensed under GPL-3.0.
