Tautree is a self-hostable, open-source Linktree alternative. Every user gets one public link-in-bio page (/[username]) with drag-and-drop link management, 6 preset themes plus custom colors, YouTube/Spotify embeds, link scheduling, and QR codes — all managed from a personal dashboard. Analytics are privacy-friendly by design (no IP, cookies, or fingerprinting), and thumbnails, QR codes, and OG images are generated in-app with zero external infrastructure.
