What is it?

Slink is a self-hosted image sharing platform built with Symfony and SvelteKit. It lets you upload, organize and share images on your own server instead of relying on a third-party image host.

Every share is private by default and reachable only by whoever holds the link. Shares can be password-protected or set to expire automatically, and images can be grouped into collections that are shared through a single link. Uploads support common formats including PNG, JPG, WEBP, SVG, GIF, AVIF and TIFF, with duplicate detection at upload time and optional compression.

For administration, Slink supports local, SMB and AWS S3 storage providers, OIDC single sign-on with providers such as Google, Keycloak and Authentik, user approval, guest uploads and an admin dashboard. It also provides API keys, a public API and ShareX integration for automatic screenshot uploads.
