What happened
StemDeck is a free, open-source, local AI stem separator that splits audio files (MP3, WAV, FLAC, etc.) or YouTube URLs into up to six stems (vocals, drums, bass, guitar, piano, other). It runs entirely on the user's machine without accounts, uploads, or subscriptions, positioning itself as a local alternative to cloud services like Moises and LALAL.AI.
Why it matters
For builders, this is a concrete example of open-source, local-first AI tools eating into niche SaaS subscriptions. Developers can study or fork the 3.2k-star repo to see how to package and distribute local AI models for end-users, while musicians and producers can use it to avoid recurring fees and keep their audio processing private.
Discussion angle
The shift from cloud-based AI SaaS to local-first open-source tools: what are the actual tradeoffs in model performance, hardware requirements, and user experience when replacing a paid service like Moises with a local app?
