Streamline

Watch Twitch streams in your local media player

---

Streamline is a GTK4/libadwaita application that lets you follow your favorite Twitch streamers, check their online status, and watch them in your preferred media player — mpv, VLC, or any custom player — all without a web browser. It also supports browsing and playing channel VODs, all powered by Streamlink.

Features

• Follow streamers — Add and unfollow Twitch streamers with a simple dialog
• Live status — See who's online and who's offline at a glance
• Stream playback — Watch live streams via Streamlink with mpv, VLC, or any custom player
• VOD browser — Browse and play past broadcasts (VODs) from followed channels
• Quick Play — Watch a one-off stream without following the channel
• Quality presets — Choose from High, Medium, Low, or set a custom quality string
• Low-latency streaming — Enable low-latency mode for faster playback
• Custom themes — Pick from Dark, Light, Bronze, Anthracite, and Red
• Export — Save your streamer list to a text file
