How to Install Slink on Your Synology NAS

How to Install Slink on Your Synology NAS

Slink is a self-hosted image sharing platform similar to Picsur, built with Symfony and SvelteKit. Slink solves the problem of sharing images with friends, family, and colleagues without relying on third-party services. It also offers a platform for artists to share their work with the community. Additionally, developers may find it useful for self-hosting screenshots of personal projects, which can then be used on GitHub, portfolios, blogs, etc. It supports the SVG, PNG, JPG, WEBP and GIF format. In this step by step guide I will show you how to install Slink on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Slink v1.0.0 release.
