Instead of StemForge
StemForge alternatives
StemForge combines stem separation, MIDI extraction, audio generation, song composition, voice conversion, mixing and export in a locally running browser workstation. Its connected tabs move outputs between these stages, and it exports WAV, FLAC, MP3 and OGG. The project is free and open source; it says audio remains on your computer and internet access is unnecessary after model downloads.

That breadth involves setup and hardware considerations: StemForge requires Python 3.12, FFmpeg and FluidSynth with a GM soundfont, and CPU-only operation is significantly slower. The Compose models require about 20 GB, Stable Audio Open requires license acceptance and authentication, and MIDI Out needs Chrome or Edge in a secure browser context. Alternatives may be a better fit for browser-first remixing, mobile or DAW-plugin access, or a different arrangement workflow. Compare how each handles stems, MIDI, exports, platforms and pricing against StemForge’s local processing and connected composition tools.
