A large playlist almost always contains a few dead links. The stream checker walks through each entry and reports which ones respond, so you can prune the ones that no longer work.
Checks run from your browser against the streams directly, giving you a realistic picture of what will actually play on your connection.
What it checks
- Whether each stream URL responds at all
- HTTP status and redirects
- Whether a valid HLS manifest is returned
- Rough response time so you can spot slow sources
How to use it
- Upload an M3U file or paste a playlist URL.
- Start the check and watch results fill in per channel.
- Export a cleaned playlist that keeps only the working streams.
