Know exactly what's in your playlist

Stream Validator checks each link and reports its real health — so you can fix or drop dead channels before your users ever hit a black screen.

Detect dead streams

Instantly flag offline, broken, and unreachable links across the whole playlist.

Spot slow streams

Surface high-latency sources that buffer, before they frustrate your viewers.

Confirm working streams

See at a glance which channels are genuinely online and ready to play.

Measure response times

Get each stream's response time in milliseconds to compare source quality.

Improve playlist quality

Export an online-only M3U and clean reports — keep only the links that work.

How to validate M3U streams

  1. Load playlist: Upload M3U, paste URL, or open a saved dashboard playlist.
  2. Start validation: Run checks on all or selected channels (uses credits per policy).
  3. Review results: See working, slow, dead, and untested rows with timings.
  4. Export clean list: Download a playlist containing only passing channels if offered.

Frequently asked questions

Is Stream Validator free to use?

Core use is free or included in your account tier. Some advanced actions may use credits — see the badge on the tool card for current pricing.

Do I need to install software?

No. Stream Validator runs in your web browser on desktop, tablet, and mobile.

Is my playlist data safe?

Many tools process locally in the browser; server-assisted tools handle files securely and do not sell your URLs or credentials.

What file formats are supported?

Standard M3U and M3U8 playlists are supported, including common IPTV attributes like group-title, tvg-logo, and tvg-id.

Will output work with TiviMate, IPTV Smarters, or Kodi?

Yes. Exported playlists follow common M3U conventions compatible with major IPTV players.

Can I use this on my phone?

Yes. The tool interface is mobile-responsive so you can upload and download from Android or iOS browsers.

Why do some streams show as untested?

CORS or provider blocking may prevent browser probes; those streams may still play in native IPTV apps.

Does validation use credits?

Yes — each check uses credits based on the current rate shown on the tool page and in your account balance.
