About Slink

Slink is a powerful self-hosted image sharing platform built with Symfony and SvelteKit, designed to give users complete control over their media sharing experience without relying on third-party services. All shares are private by default, with optional password protection, expiration times, and collection-based sharing via a single link. Slink supports a wide range of image formats including PNG, JPG, WEBP, SVG, AVIF, HEIC, and TIFF, with multi-file parallel uploads, image compression, and deduplication on upload. It features SSO and OIDC support for Google, Authentik, Keycloak, Authelia, Pocket ID, and custom providers, along with personal API keys and a public API. Storage backends include local, SMB, and AWS S3. The admin dashboard provides analytics, user management, image moderation, and storage tracking. Slink is available in nine languages and supports both dark and light modes.
