MOL2 has the best EPG guide that I know of but The only other experience I have is with MAG Box and Buzz Tv.
MOL2 is on Formuler boxes.
Have you tried m3u4u ? it's free and they have a discord group support too
TiViMate has a great EPG
I am looking for a good IPTV EPG Guide
I think he is asking for an EPG SERVICE!!!!
not an interface.
