alldebrid. their 4.0/4.1 api has all the stuff to decode magnets and browse their files. filter mkv,mp4,etc. i made a little database of imdb tt values to assist autosuggest for searching and a nsfw filter for the few friends and family using the app.

have thought about extending it to realdebrid/torbox/etc but it's just been kinda set and forget. every once in a while will add a feature... most recently i think was seeing if there was a matching srt file and feeding that along with the video file to vlc so you get subtitle support if it's not baked into the video file
