Device guide
Most Fire TV devices can run IPTV through a player app that supports Xtream Codes or M3U logins. The important exception is newer sticks running Amazon's Vega OS, such as the Fire TV Stick 4K Select, which only install apps from the Amazon Appstore — so check your model before you subscribe.
Device testing in progress
We haven't yet published a tested app list for this platform. Before you buy, check that a player app supporting Xtream Codes or M3U is available in your device's app store.
Covers: Fire TV Stick (Fire OS models) · Fire TV Stick 4K / 4K Max · Fire TV Cube · Fire TV Edition smart TVs
Check your Fire TV software: go to Settings → My Fire TV (or Device & Software) → About and note whether it shows Fire OS or Vega OS.
Open the Amazon Appstore on your Fire TV and search for an IPTV player app that supports Xtream Codes or M3U playlists. Install it.
Open the app and choose the option to add a playlist or login. Pick Xtream Codes (enter the server URL, username and password exactly as sent to you) or M3U URL (paste the full playlist link).
Wait for channels and the program guide to load. The first load can take a minute on large playlists.
Open a channel to test playback. If it buffers, try a wired connection or see the buffering guide linked below.

For years, every Fire TV ran Fire OS, which is based on Android. That meant you could install IPTV player apps from the Amazon Appstore and, if you chose to, from other sources. In 2025 Amazon released the Fire TV Stick 4K Select on a new operating system called Vega OS, and said future Fire TV Sticks would run Vega as well. On Vega OS, apps can only come from the Amazon Appstore — there is no setting for installing apps from other sources.
In practice: on a Fire OS device you have the widest choice of player apps. On a Vega OS device you are limited to whatever IPTV players are published in the Appstore for Vega. If you are buying a new streaming device specifically for IPTV, confirm the operating system first.
It depends on the player apps available for your model. Fire OS devices have the widest app choice. Vega OS devices, starting with the Fire TV Stick 4K Select, can only install apps from the Amazon Appstore.
No VPN is needed to make a lawful IPTV service work. Some people use one for privacy, but a VPN adds overhead and can reduce speed, so try without one first if you have buffering.
Sticks sit behind the TV, where the Wi-Fi signal is often weakest. Use the HDMI extender, switch to 5 GHz, or add an Ethernet adapter.
