Self-hosted and plugin-based, DVinyl keeps vinyl, CDs, cassettes, books, movies, video games, LEGO sets, and board games in one catalog, with cover art and metadata fetched for every item. Adding an item takes an ID, a camera scan of its barcode, or a bulk import from Discogs or Goodreads. Each media type is a plugin that switches on per collection, with Discogs behind music, TMDB behind film, IGDB behind games, and Rebrickable behind LEGO. Once cataloged, a collection appears as a grid, a compact table, or virtual shelves with spine view and customizable furniture. Custom lists, track playlists, and a wishlist of items still being hunted sit alongside. Music collections get live value estimates with price history charts, games show completion times, and printable QR codes and barcodes label the physical copies. Separate collections can belong to you, the family, or a room, each with admin, editor, and viewer roles and optional OIDC single sign-on through Authentik, Keycloak, Authelia, or pocketID. Read-only links and QR codes let anyone browse a whole collection or just one section. Fourteen themes in light and dark, a modular dashboard, and a Markdown info page with photos make each instance personal. A no-code editor adds custom item types.
