FreeMix License Framework

The FreeMix License Framework is a licensing system designed specifically for music. Not adapted from software licenses (MIT, GPL) or generic creative licenses (Creative Commons) — built from the ground up for how music is actually shared, remixed, and performed.

Every track, stem, or sample you upload gets a license tier. The tier tells other users exactly what they can do with your music.

The format is straightforward:

FM:[Tier] · [Modifier] · [Modifier] · ...

For example: FM:Remix · Credit · Royalty(10%)

That tells you: this track can be remixed, the original artist must be credited, and they receive 10% of any commercial sales of derivatives.

TierWhat it allowsCommercial use?Best for
FM:OpenAnything goes — remix, sample, redistributeYesTracks you want maximum reach for
FM:RemixRemix and sample freelyYes (unless modified)Most electronic music
FM:NCRemix for non-commercial use onlyNo (negotiate separately)Protecting commercial rights
FM:StemsUse individual stems, full track protectedYes (for derivatives)Sharing production parts
FM:DJPublic performance, no file sharingYes (performance)DJ-friendly edits
FM:SamplesBuilding blocks — 0% royalty alwaysYesOne-shots, loops, snippets

Modifiers add requirements or restrictions on top of the base tier. When multiple modifiers are present, they always appear in this fixed order:

CreditMixRoyalty(n%)ShareAlikeNoAI

This ensures one canonical string per license. FM:Remix · Credit · Royalty(10%) · ShareAlike is correct; FM:Remix · ShareAlike · Royalty(10%) · Credit is not.

ModifierWhat it does
CreditAttribution required — credit the original creator
MixTransparency flag — the work contains a mix of licensed and unlicensed content
Royalty(n%)Original creator receives n% of revenue from commercial sales of derivatives
ShareAlikeDerivatives must carry the same FreeMix license tier or more restrictive
NoAIMay not be used for machine learning or AI training data

Full modifier details →

  • Clarity over brevity — You should understand what a license allows just by reading its name.
  • Creators should be able to earn from their work — The Royalty modifier ensures original creators are compensated when derivatives generate revenue.
  • Free first — FreeMix is a free platform. Commerce features with optional royalties are planned for the future.
  • Transparency over prohibition — Especially regarding AI. FreeMix requires honest disclosure rather than blanket bans.

Licenses aren’t just badges on a webpage. They’re embedded in the protocol as structured data — stored as AT Protocol records that any application can read and enforce. When you set a license, it’s part of the permanent record.
