IPTV Playlist Formats Compared: M3U, JSON & Xtream Codes
M3U is the most common format, but a few others exist — here's a quick technical comparison for the curious.
M3U / M3U8
A simple text-based playlist listing channel names and stream URLs — see the full format explanation.
Xtream Codes API
Not a static file at all — a live API returning data dynamically based on login credentials. See how it works.
JSON-based formats
Some newer or custom systems use JSON to structure channel and EPG data — functionally similar to Xtream Codes in being a live, structured data format rather than a static file, though less standardized across the industry.
Which one you'll actually use
As a subscriber, your provider determines which format(s) are offered — most, including Xtreme HD IPTV, support both M3U and Xtream Codes for maximum player app compatibility.
