M3UBox: A Fast, Clean Player for Any M3U Playlist

By Po November 10, 2026
I built a free, browser-based player for M3U and M3U8 playlists after getting fed up with slow, ad-ridden alternatives. Everything runs in your browser, and there is a radio directory built in.

It started over a fence

My neighbor, a pensioner, was complaining about his TV bill. Nearly $50 a month. He asked whether he should switch providers. I don’t watch traditional TV myself. I can’t stand the ad breaks, and I see maybe a handful of movies a year. But I remembered friends mentioning internet TV services that cost a fraction of that, so I started digging into how they work.

That digging led me somewhere unexpected: GitHub. Public repositories hold huge collections of .m3u8 playlists, many of them pointing to free-to-air channels, public broadcasters and community-maintained lists such as iptv-org. Some playlists out there point to content that isn’t licensed for redistribution, and that’s not what this tool is for. Use playlists you have the right to use.

What M3UBox does

  • Parses big playlists in your browser. Load an .m3u or .m3u8 file and it’s searchable in moments.
  • Sorts channels for you. It reads the playlist metadata and lets you filter by category, language and region.
  • Includes a radio browser. Powered by the open Radio Browser API, you can pick a country and stream thousands of live stations without loading any playlist at all.

Privacy

Playlists are processed client-side. There is no account and no tracking.

The HTTP stream problem

A lot of free streams use plain http:// links, and this causes two separate headaches in a browser:

  • Mixed content. A secure (https) page won’t load insecure (http) media, so those streams fail.
  • CORS. Even over https, a server that doesn’t send the right headers can’t be fetched by script, which limits things like stream checks.

You have two options. The easy one is the “Only HTTPS Streams” filter, which hides the insecure links so everything left just works. The thorough one is running your own local HLS proxy that rewrites the traffic, for example m3u8_proxy-cors.

Limitations

  • You can’t save or import a favorites list yet.
  • Some streams will always fail because of the http and CORS issues above.
  • It’s a work in progress. If there’s enough interest I may add features.

Try it

M3UBox is free. Load a playlist you’re entitled to use, or jump straight into the radio section, and tell me what breaks or what you’d like next.
