which tracker should I use?
 

I tested:
U-232
PU-239
Unit3D
xBTiT
TSUE

what tracker that I have not tested and is still developing and have more supports? eg. theme, hacks (bonus)...
a little bit flooded by all the codes avaiable, thanks

(anyone have demo sites...or pictures for those I have not tested?)
thinking about:
XBTIT Blu-Edition by BluCrew v2.0.9 unoffical
empornium/luminance
oppaitime/gazelle

Unit3D is likely the only source code under heavy development and you should give it a closer look. It is the only open source code that is using any php framework.

you could use my fork of rartracker:

https://github.com/ERR1R/rartracker

Simple to install, just change the domain name.

The below are still being actively developed and both have Demo Sites.

FreeTSP

BTManager

I don't expect I can see Admin answering my post! Thanks!
I tested freetsp and btmanager, it seems that it is a little bit incompatible with PHP7?
I decided either using Unit3D or XBTIT Blu, just more works to do to make it suitable for software and ebooks...no need imdb stuffs...
Thanks! Thanks!

BTManager will work with php 7.2.7

rartracker is only using imdb when you fill in the imdb url. its light and fast!
it also works with php7 and uses an api so you can easy upload/download from script
