## Common questions

### Is there a free, open-source alternative to Suno?

Yes. ACE-Step 1.5, ACE-Step Studio, HOT-Step CPP, ACE-Step UI and YuE2 are free to download and run on your own computer without paid API keys. ACE-Step 1.5, ACE-Step Studio and ACE-Step UI cover every job we list for Suno; the others cover only part of it, so check which job you need.

### Can I do full songs with vocals from a prompt or lyrics locally without a Suno subscription?

Yes, with ComfyUI (GPL-3.0), ACE-Step 1.5 (MIT) and YuE2 (Apache-2.0 code, CC-BY-NC-4.0 weights). Check the hardware notes and licence conditions on each page before you start.

### Can I do instrumental tracks (Instrumental mode) locally without a Suno subscription?

Yes, with ACE-Step 1.5 (MIT), YuE2 (Apache-2.0 code, CC-BY-NC-4.0 weights) and yovoice (Apache-2.0). Check the hardware notes and licence conditions on each page before you start.

### Which Suno alternatives can I use commercially?

Confirmed: ACE-Step 1.5, ACE-Step Studio, acestep.cpp, HeartMuLa, Magenta RealTime 2 and Ultimate Vocal Remover. With conditions: ComfyUI, DiffRhythm, HOT-Step CPP, Stable Audio Open (stable-audio-tools), yovoice, YuE2 and YuE2 Studio. Not for commercial use: AudioCraft (MusicGen), usually because the model weights are non-commercial. This is not legal advice; read each licence.

### Does any open-source project replace all of Suno?

ACE-Step 1.5, ACE-Step Studio and ACE-Step UI cover every job we list for Suno.
