The trade-offs
Strengths and Limitations
Google Flow Music
Strengths
- Songs are edited in conversation instead of regenerated, with tempo and duration under direct control
- Downloads cover MP3, WAV and M4A, and stems can be split out
- A free tier with daily credits, and paid plans start at $6 a month
- Music videos and a build-your-own area for plugins and instruments sit in the same product
Limitations
- Commercial use and licensing of the output are not spelled out on the product site, which links to Google's general Terms of Service
- No public API is documented
- The service has been renamed twice, so guides and links written for Riffusion or Producer.ai go stale quickly
Loudly
Strengths
- Exports full tracks, stems and samples in WAV and MP3
- Royalty-free tracks cleared for release on streaming platforms
- Music generation API for apps and games
Limitations
- Instrumental only, no vocals or lyrics
