Stretto

Stretto is an open-source, web-based music player that lets you build and play a personal library backed by YouTube or SoundCloud sources. It focuses on a clean player experience, playlist importing, and syncing your library across devices.

Key Features

• Builds your music library by matching tracks to YouTube videos or SoundCloud audio
• Spotify playlist import to quickly populate your library
• Library syncing between machines
• Automatic lyric fetching for the currently playing track
• Music discovery via popular charts and search-based adding of tracks
• Multiple themes and a progressive web app style experience for mobile use

Use Cases

• Create a personal web music library without managing local audio files
• Import existing Spotify playlists to a self-hosted web player
• Sync a listening library across multiple computers and browsers

Limitations and Considerations

• Some functionality relies on third-party services (YouTube, SoundCloud, Spotify) and their availability/quotas
• Full experience may depend on a companion browser extension for downloading tracks into the browser

Stretto is a good fit if you want a polished, browser-first music player with playlist import and cross-device syncing. It is best suited for users comfortable integrating external music sources into a self-hosted web app.
