Replace Moises?

NOT REALLY · don't bother

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Moises, run a local stem-separation model and build practice controls for user-owned songs. The hard boundary is proprietary separation models, mobile polish, chord detection, cloud compute, and speed, plus licensed content, rights, and distribution network.

the prompt
Build a closest honest personal substitute for Moises in an empty repository.
Use Python 3.12, FastAPI, SQLite, ffmpeg, and a local web interface; do not offer alternative stacks.
The core loop is: run a local stem-separation model on legally owned or user-created tracks, then provide private practice controls and playback for each song.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Index only user-selected folders and preserve source audio without modification.
Read tags and artwork, calculate loudness and waveform data, and detect exact duplicates by hash.
Provide albums, artists, playlists, search, queue, favorites, and resumable local playback.
Add optional creator tools for trim, normalize, split stems through a local model, and export new files.
Keep all rights and source information attached to imported tracks and display it during export.
Document that the application does not provide music, licensing, distribution, or royalty collection.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out copyrighted catalog acquisition or sharing.
Deliberately leave out streaming-service circumvention.
Deliberately leave out royalty accounting, label distribution, and global content delivery.
Finish by running the tests and listing the exact commands used.

why people still pay

People still pay for Moises because the product is the catalog, rights chain, and distribution network; a player or processing tool is only the visible edge. The recurring cost buys catalog licensing, royalties, identity, content delivery, moderation, recommendations, payouts, codecs, and rights disputes, not just the visible interface.

What do I lose by replacing Moises?

Honestly: proprietary separation models, mobile polish, chord detection, cloud compute, and speed; licensed music catalog; royalty and distribution relationships; global streaming infrastructure; artist network and recommendations. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Moises?

The listed prior art includes Navidrome (Active open-source personal music server for legally owned libraries.). Inspect those projects before starting from a blank prompt.
