Introduction to Slink

Welcome to Slink, a self-hosted image sharing platform designed to give users complete control over their media sharing experience. Built with Symfony and SvelteKit, Slink enables secure image sharing without relying on third-party services.

Why Slink?

Artists: Showcase artwork in a community-focused platform.
Developers: Host and share screenshots for GitHub, portfolios, blogs, and more.
Anyone: Take control of image privacy and hosting.
