vs Debrid Media Manager
Debrid Media Manager is for managing a debrid library by hand: searching torrents, removing duplicates, syncing Trakt lists and sharing libraries across Real-Debrid, AllDebrid and TorBox. StreamBridge is for the next step: picking a movie and watching it in Plex.
DMM is a free, open-source web app. It searches for torrents, shows what's already in your account, groups titles, removes duplicates, syncs Trakt watchlists and collections, offers a Stremio addon, and lets you share or mirror libraries.
DMM decides what goes in the library, and you play it through WebDAV, a media player, a media server or its Stremio addon. StreamBridge puts the titles you pick into your Plex library, so every Plex app can play them. DMM is for people who care about the exact release: remux or encode, file size, which provider. StreamBridge is for people who want the movie to play without sorting releases first.
Use DMM if you want a full workbench for a debrid library. Use StreamBridge if you mainly want to pick movies and watch them in Plex with as little library management as possible.
