ACE-Step API vs Loudly

ACE-Step API has no write-up on Specifiction yet; its figures are above.

Loudly is a web-based AI music generator from a maker headquartered in Berlin, Germany. It supports vocal generation, audio uploads and stem export, with downloads in MP3 and WAV formats. Commercial use is supported, so listed rights cover commercial projects. The Free plan costs nothing and limits generated tracks to 30 seconds. Personal includes AI music generation, downloads and commercial licensing. Pro lists higher generation, download and stem allowances, also with commercial licensing. Because the listed platform is web, the service is accessed through a browser rather than a separately listed desktop or mobile application. Audio upload and stem export provide ways to incorporate existing material and separate generated parts. The defined free-track duration gives the no-cost option a clear boundary, while the paid plan descriptions indicate expanded allowances and licensing for users who need more output.
