The honest brief
Sonauto
Uses latent diffusion in continuous space, not an audio-token LM like most rivals — pitched as fast, steerable full songs, plus an API.
- Generates full songs with vocals
- Prompt, lyrics, or hummed-melody input
- Developer API
- Free tier available
- Smaller name than Suno/Udio
- Quality varies by genre
- Commercial use needs paid plan
Stable Audio
Trained on AudioSparx-licensed music, pitched as commercially clean — unlike rivals trained on scraped audio now facing lawsuits.
- Music + sound-effects generation
- Trained on licensed data
- Web studio plus generation API
- Backed by Stability AI
- Vocals weaker than song-first rivals
- Free tier limits length/generations
- Commercial use needs subscription
