zspot is licensed under the GPL-3.0, like cspot, from which the Spotify protocol core is derived. The Tremor Vorbis decoder is BSD-licensed (see lib/zspot/third_party/tremor/COPYING).

Threads, sockets, TLS, crypto (PSA), mDNS, JSON, protocol buffers (nanopb), LVGL and audio output come from Zephyr and its modules under their own licences.

Zephyr is a trademark of The Linux Foundation. Spotify is a trademark of Spotify AB and identifies the Spotify Connect protocol only; this project is not affiliated with or endorsed by Spotify or the Zephyr Project.
