What is an M3U link?

An M3U link points to a text playlist file listing channel names and their stream URLs. Your IPTV provider gives it to you as one long link that includes your username and password. You paste it into an IPTV player, which reads the list and shows the channels. An M3U link often comes with a second XMLTV link for the programme guide (EPG), because the M3U file alone doesn't contain schedules.

What is Xtream Codes API?

Xtream Codes API is a login made of three details: a server URL (such as http://example.com:8080), a username and a password. Instead of downloading one big playlist, the app talks to the server directly and pulls channels, movies and series in organised categories, with the programme guide included automatically.

M3U vs Xtream Codes: the differences

M3U linkXtream Codes API
FormatOne long linkServer + username + password
Programme guide (EPG)Usually a separate linkAutomatic
Movies and seriesAll in one listOrganised into categories
Loading speedSlower with large listsFaster
AppsAlmost every player, including VLCIPTV Smarters, TiviMate and most modern players

Which one should you use?

Use Xtream Codes whenever your app supports it: it's faster, organises movies and series and loads the guide automatically. Use the M3U link when the app only accepts playlists, such as VLC on a computer or some smart TV apps. If you're a NeonIPTV subscriber and need a specific format for your device, contact support on WhatsApp.
