BacklogBox is a media backlog tracker that combines book, movie, TV show, game, and podcast tracking into one app. Instead of juggling Goodreads, Letterboxd, Backloggd, and Trakt, you get a single Kanban board per media type.

As answered by people managing BacklogBox and git-sizer.
BacklogBox's answer
It is the only media tracker that covers books, movies, TV shows, games, and podcasts in a single app with Kanban boards. Instead of maintaining separate accounts on Goodreads, Letterboxd, Backloggd, and Trakt, everything lives in one place. You also get custom lists for tracking anything that does not fit the built-in types
BacklogBox's answer
BacklogBox is an early-stage product for individual users. There are no enterprise customers — it is built for people who want to organize their personal media backlogs.
BacklogBox's answer
SvelteKit, TypeScript, PostgreSQL.
BacklogBox's answer
I was using Letterboxd for movies, Goodreads for books, Backloggd for games, and a spreadsheet for TV shows. Every time I finished something I had to remember which app to open. Half the time I just forgot. So I built one app to replace all of them.
BacklogBox's answer
People who consume multiple types of media and want a single place to organize it. Readers who also game, movie watchers who also follow TV shows, anyone with a growing backlog across different media types who is tired of juggling separate apps or spreadsheets.
BacklogBox's answer
Most media trackers only cover one type — Letterboxd for movies, Goodreads for books, Backloggd for games. If you consume multiple types of media, you end up with five different apps and no unified view. BacklogBox gives you one Kanban board per media type, auto-searches from TMDB, OpenLibrary, IGDB, and Apple Podcasts, and has a Discover page for finding new content across all categories.
