Uguu is a lightweight, self-hostable temporary file hosting platform written in PHP, aimed at individuals and teams who want quick drag-and-drop or API-based file sharing without registration or a third-party service.

What it is

Uguu is a simple temporary file hosting and sharing platform built in PHP, which can also be used as a permanent file host. It lives in the file-hosting category alongside lightweight pomf-style hosts, and it is based on Pomf, written by Emma Lejack and Go Johansson (nekunekus/nokonoko) with help from the open source community. It is released under the GPL-3.0 license and is written following PHP PSR-12 coding style guides, enforced with PHPCS tools.

The concrete problem it solves is sharing a file quickly without signing up for an account on someone else's service. Uguu offers one-click uploading with no registration required, a minimal modern web interface, and support for drag, drop, and paste, so a screenshot or document can be uploaded and a link returned in a single action. It is tested and working with Nginx plus PHP 8.3 and SQLite, MySQL, or PostgreSQL, and it is compiled with Bun before running on PHP.

Key capabilities

• Upload through one click, drag and drop, and paste directly into a minimal web interface.
• An upload API with multiple response formats: JSON, HTML, Text, and CSV.
• Compatibility with ShareX and other screenshot tools.
• File extension and MIME blacklisting or whitelisting.
• Upload rate limiting to control how much traffic a deployment accepts.
• File hash blacklisting for blocking specific uploaded content.
• Choice between SQLite, MySQL, or PostgreSQL as the backing database.

Who uses it and how

• Operators of public file hosts running Uguu behind Nginx with PHP 8.3, as demonstrated by the real-world site at uguu.se.
• Individuals self-hosting a personal file host from their own server, keeping files on infrastructure they control.
• Users of screenshot and upload tooling such as ShareX, pointing their clients at the upload API and choosing a JSON, HTML, Text, or CSV response.
• Administrators who need policy control over uploads, applying extension and MIME rules, hash blacklisting, and rate limits to what their instance accepts.
• Teams and contributors working on a PHP codebase under PSR-12 style, using PHPCS enforcement and submitting feature requests, documentation, or tests.

Getting started

Installation and configuration are documented in the Uguu Configuration & Installation page of the project's GitHub wiki; Bun is used to compile Uguu, after which it runs on PHP under Nginx with SQLite, MySQL, or PostgreSQL.

How it compares

Uguu stands alone in this registry as a PHP-based, GPL-3.0 temporary file host built on the pomf lineage, with the topics and feature set described above being what distinguishes it here.

When to use it — and when not

A self-hoster must run a web server with PHP 8.3, a database backend (SQLite, MySQL, or PostgreSQL), and the Bun build step, plus configure upload policies such as rate limits and MIME rules. It is not a fit for those unwilling to operate that stack or who need hosted, managed sharing out of the box. Note that the README is brief and defers setup details to an external wiki, and the project carries a small number of open issues.
