What is Miusix?

Miusix is an open-source, self-hosted music server and cross-platform music player built with React, Expo, Fastify, yt-dlp, PostgreSQL/Supabase, Cloudflare Tunnel, and Vercel.

It keeps the entire listening loop in one TypeScript monorepo:

• Search a configured provider from Web, iOS, or Android.
• Cache music you are authorized to save through an opt-in yt-dlp adapter.
• Store stable track IDs and metadata in PostgreSQL or Supabase.
• Keep media files on local disk today, with object storage as the next step.
• Stream seekable audio with HTTP range requests.
• Save favorites and playlists, then add a whole playlist to the play queue.
• Run the API at home and expose it securely through Cloudflare Tunnel.

Important

Miusix is for software research, self-hosting, and media you own or are authorized to save. The provider adapter is disabled by default and does not bypass DRM, authentication, or paywalls.

The experience

Editorial Web listening room	390 × 844 tactile iOS turntable

The two interfaces keep separate rendering runtimes instead of restyling one React tree, but now live inside the same frontend application. / is the Web library, search, playlist, and queue workspace. Switching to /ios/ keeps the React shell mounted and embeds the original tactile HTML in a same-origin frame. React passes the configured API endpoint into that frame, where search, yt-dlp import, audio streaming, favorites, playlists, and customization remain available without compromising the reference layout.

Responsibility map

Service	Role in Miusix	Required?
GitHub	Source, branches, pull requests, issues, and Vercel integration	Yes for this repository
Vercel	Hosts the static React Web player and preview deployments	Recommended
Cloudflare Tunnel	Gives a local API an HTTPS URL without opening router ports	Optional; Quick Tunnel works for demos
Nginx / Caddy	Routes one tunnel or domain to Miusix and future local services	Recommended for multi-app hosting
Fastify	Search, import jobs, metadata APIs, and seekable audio streaming	Yes
yt-dlp	Opt-in provider adapter for search and authorized media caching	Optional
Supabase / PostgreSQL	Stable IDs, metadata, source references, status, and future user playlists	Recommended
Media storage	Stores the actual audio file; local disk now, object storage later	Required for cached media

What belongs in the database?

Store IDs and metadata, not the audio bytes:

erDiagram
    TRACKS ||--o| MEDIA_SOURCES : has
    TRACKS }o--o{ PLAYLISTS : appears_in
    TRACKS {
      uuid id
      text title
      text artist
      int duration_seconds
      jsonb artwork
      text media_path
      text download_status
    }
    MEDIA_SOURCES {
      text provider
      text external_id
      text source_url
    }
    PLAYLISTS {
      uuid id
      text title
      uuid_array track_ids
    }

Loading

The audio file lives in storage/media or object storage. PostgreSQL/Supabase keeps the stable UUID, provider ID, metadata, path, MIME type, and download status.

Run it

Full self-hosted stack

cp .env.example .env
# Set a strong POSTGRES_PASSWORD.
# Enable imports only for media you are allowed to save:
# ENABLE_YOUTUBE_IMPORTS=true
docker compose up --build -d

The local endpoints are:

Endpoint	Purpose
http://localhost:3000	Web player
http://localhost:4000/health	Fastify health check
http://localhost:4000/v1/search?q=Adele	Provider search

Local development

npm install
cp .env.example .env
npm run dev:api

In another terminal:

npm run dev:web

For iOS and Android development:

npm run dev:mobile

Expose the local API with Cloudflare Quick Tunnel

cloudflared tunnel --url http://127.0.0.1:8080

Point Nginx or Caddy at the API and Web containers first, then expose that single reverse proxy. When you own a domain, replace the temporary Quick Tunnel URL with a named tunnel and hostname routes.

For AI agents

This repository is intentionally structured for coding agents:

1. Read AGENTS.md before changing files.
2. Create a feature/<short-description> branch. Never work directly on main.
3. Keep secrets, .env, downloaded media, dependencies, and build output out of Git.
4. Run npm run typecheck and npm run build.
5. Push, open a PR, wait for Vercel checks, merge, and delete the merged branch.
6. Use GitHub issues and the codebase as the source of truth.
