BasedOn started as a simple idea for a Stremio addon: what if every movie and series could show you its original source? The novel it was based on, the true story that inspired it, the earlier film it remade.
While building the addon, I realized something: there was no centralized source for this information. So I started building that reference myself.
BasedOn is now a database of adaptations, remakes, reboots, spin-offs, collections, and creative sources. It tracks whether a movie or series is based on a novel, book, short story, comic, manga, play, video game, true story, memoir, or another film — and connects each adaptation to its origin.
Information is cross-referenced and verified from multiple sources. The goal is simple: create the most complete reference for "what is this based on?" — for Stremio users, and for anyone curious about the stories behind the screen.
BasedOn is built and maintained by zorak2d, an indie developer working on passion projects for the Stremio community.
I maintain it in my spare time, adding new features, improving data quality, and fixing the occasional inaccuracy.
If you spot an error or have a suggestion, you can report it directly from any title page — every report helps improve the database.
