Attributions

kino stands on the shoulders of an enormous amount of open-source software and a handful of third-party services. This page acknowledges the load-bearing pieces.

Third-party services

TMDB ↗

Not affiliated with or endorsed by Trakt.tv.

Notable open-source dependencies

Selected highlights — kino's full SBOM (every Rust crate + npm package, generated by cargo-about) lives at THIRD_PARTY_LICENSES.md in each release archive.

FFmpeg ↗
GPL-3.0

Transcoding, probing, every audio/video operation. kino does not bundle FFmpeg in its release archives — Settings → Playback offers an in-app download of upstream jellyfin-ffmpeg portable builds. Source-offer obligations under GPL §6 rest with Jellyfin as the redistributor of the binary kino fetches; see docs/third-party/ffmpeg-source-offer.md.
boringtun ↗
BSD-3-Clause

Userspace WireGuard implementation. Built-in privacy networking is a thin wrapper around boringtun + the tun crate.
librqbit ↗
Apache-2.0

BitTorrent client embedded directly in the kino binary. No external download client required.
Cardigann YAML format ↗
GPL-2.0

Indexer definition format originated by the Cardigann project. kino's indexer engine consumes definitions in this format when the user opts in.
Astro + Starlight ↗
MIT

Powers this website (kinostack.app) and the docs site (docs.kinostack.app).
shadcn/ui + Radix ↗
MIT

UI primitives (dialogs, dropdowns, tooltips) inside the in-app SPA.

Licensing posture

kino itself is licensed under GPL-3.0-or-later. Every dependency we ship is GPL-compatible (MIT, Apache-2.0, BSD, ISC, MPL-2.0, LGPL-3.0, or other GPL-3.0). Drift is caught automatically by cargo-deny on every build.
