NextBeats

NextBeats is a web-based lofi music player that combines YouTube stream playback with ambient sound effects and a retro-inspired interface. It is built with Next.js and TypeScript, provides persistent local channel and effect management, and is optimized for desktop and mobile browsers.

Key Features

• Retro TV-style UI with theme customization and responsive design
• YouTube integration for continuous lofi streams using client-side playback
• Multiple ambient sound effects (rain, cafe, fireplace, typing, etc.) with independent volume controls
• Channel management: add, edit, and delete custom YouTube channels saved locally
• Per-effect and master volume mixing for fine-grained atmosphere control
• Persistent settings stored in localStorage for per-device personalization
• Docker support and straightforward Node.js development workflow

Use Cases

• Provide unobtrusive background music for coding, studying, or relaxation
• Create personalized ambient soundscapes by mixing music streams and effects
• Maintain a curated list of favorite lofi streams and custom channels per device

Limitations and Considerations

• Mobile browsers restrict programmatic volume control, so users may need to use device volume buttons to adjust sound levels
• Playback depends on YouTube embeds/streams; removed or region-restricted videos will no longer play
• Channel and effect data is stored locally and does not sync across devices or users

NextBeats is a lightweight, opinionated player for ambient listening that emphasizes customization and local persistence. It is well suited for personal use and quick self-hosted deployments for individuals or small groups.
