Privacy
Results are never shared. Choose “This browser” and the fetch and the analysis both happen on your machine — the URL, any headers you set and the results never reach our servers, which is also how you test a stream on a private network or behind a login. Pasted content is always analysed locally.

Frequently asked questions
- What does the M3U checker check?
- tvg-id coverage and duplicates — the join key to your programme guide. Duplicate channels, missing names, and unplayable URL schemes. Logo and group-title coverage across the whole playlist. Per-channel user agent, referrer and Kodi DRM properties. Whether the playlist declares an EPG source at all.
- Is the M3U checker free?
- Yes. Every tool on StreamTest is free and works without an account. Sign in only to keep a private history.
- Can I test a stream on a private network or behind a login?
- Yes. Choose "This browser" and the fetch and the analysis both run on your machine — the URL, any headers you set and the results never reach our servers, so local, staging and authenticated origins work.
- Do you support custom request headers and DRM keys?
- Yes. You can set Authorization, User-Agent, Referer and Cookie headers per test, and supply cleartext ClearKey keys for encrypted DASH so the preview plays.
