ACE-Step UI is an open-source, professional web interface for the ACE-Step 1.5 music generation model, positioned as a free, local-first alternative to subscription services like Suno. It wraps the powerful open ACE-Step foundation model in a polished React application so anyone can compose full songs on their own machine. The project has gathered more than 5,000 stars on GitHub and is under active development.
ACE-Step is one of the leading open models for text-to-music generation, capable of producing complete songs with vocals and lyrics across many genres. On its own it ships as research code; ACE-Step UI turns it into a studio-like tool. You describe a style, write or generate lyrics, set duration and generation parameters, and the app queues, renders and organizes your tracks locally, with no per-song credits and no uploads to a third-party service. Because everything runs on your hardware, generation is unlimited and your unfinished demos stay private.
The interface exposes the model’s main creative controls, including style tags, lyric structure markers and seed settings, and it keeps a library of generated tracks together with the prompts that produced them. It is designed for desktop use and installs alongside the ACE-Step backend in a single setup.
ACE-Step UI is free and open source. There is no paid tier and no generation credits to buy; your only cost is the computer or GPU you run it on.
ACE-Step UI is for musicians, producers and hobbyists who want Suno-style AI songwriting without a subscription, and for tinkerers who prefer open models they can run, inspect and modify locally.
