Free M3U8 Player Online and HLS Stream Tester
Paste a direct M3U8 URL to test HLS playback in your browser. The free player shows quality levels and resolution changes, while the manifest inspector reads variants, codecs, segments, tracks, keys, and referenced hosts.
Stream requests go from your browser to the media origin; this site does not proxy the URL. Export the on-page event log when you need a concise record of manifest, network, recovery, and playback signals. DASH, MP4, and WebM testing remain available in the other tabs.

Follow each browser-side playback step
The log stays in this browser tab and records player events without uploading your stream URL.
- No events yet. Load a stream to record manifest, quality, recovery, and playback signals.
Read the playlist before debugging the player
The inspector fetches the M3U8 file directly from your browser and summarizes what it references. It does not proxy or upload private stream URLs.
What this player helps you verify
The tool is most useful when it turns a vague playback complaint into a concrete delivery signal. It does not proxy your stream or hide browser rules; it shows whether the browser can reach, parse, and play the resources your own users would request.
Can the manifest load?
If the first M3U8 or MPD request fails, check the URL, token freshness, status code, and cross-origin policy before changing player code.
Are quality levels visible?
When quality options appear, the playlist has been parsed and the next checks move to selected variants, segment paths, and codecs.
Do media requests continue?
Segment-level failures often come from CDN rules, signed URL expiry, mixed origins, or encryption-key requests that are blocked separately.
Does the browser decode it?
If network requests succeed but playback does not render, compare codecs, init segments, browser support, and autoplay restrictions.
Use the tool, then go deeper with the matching guide
Start with the direct URL
Use a public manifest or file URL so you can verify whether the stream itself is accessible before debugging app code.
Choose the right playback mode
Select HLS, DASH, or MP4 based on the real source type. A correct stream can look broken when the mode is wrong.
Watch for status and quality changes
Resolution, quality levels, and player state help you see whether the manifest loaded, media initialized, and adaptive playback is working.
