There will be other non JS-based clients to access PeerTube, but for now none is available. Be sure we will update this page with a list once alternative clients are developed. You can certainly develop you own in the meantime as our code is open source and libre software under GNU AGPLv3.0.
We are sorry but it seems that PeerTube is not compatible with your web browser.
Please try with the latest version of Mozilla Firefox.
If you think this is a mistake, do not hesitate to report it.
