Slink

Slink is a self-hosted image sharing platform that gives you control over how your pictures are stored and shared, without depending on a third-party host. It is built with Symfony and SvelteKit, and the project tags it as an Imgur alternative for people who want private galleries and links.

Shares are private by default and reachable only through their link, with optional password protection and expiry times, plus a page for listing, editing, publishing and revoking them. Collections group images under one link, and an Explore page shows publicly visible images. It handles many image formats, parallel multi-file uploads, compression and duplicate detection, supports guest uploads, and integrates with ShareX for screenshots. Storage can use S3 or SMB.

Slink is licensed under AGPL-3.0 and delivered as a Docker deployment, with documentation and a live demo online. It supports OIDC single sign-on, which makes it practical for homelabs and small teams. The README says it suits artists, developers sharing screenshots and anyone who wants image privacy under their own control.
