Slink is a self-hosted image sharing platform designed for privacy-focused users, developers, artists, and self-hosting enthusiasts who want full control over their image uploads and shares.
🚀 Overview
Slink is a powerful, open-source image sharing service that lets you upload, organize, and share images on your own server. It replaces unreliable third-party hosts like Imgur with features like multi-file uploads, automatic deduplication, nested tagging, and customizable share links.
The project solves the problem of images expiring or being censored on external platforms, while ensuring complete data privacy and no vendor lock-in. It's built for anyone tired of big tech controlling their media.
Developed by Andrii Kryvoviaz, Slink emphasizes ease of self-hosting with Docker support and modern UIs.
