ACE-Step Studio is a local-first, Suno-style music studio that lets you generate and manage AI music on your own hardware using ACE-Step 1.5 as the engine. The stack combines a FastAPI backend that handles generation, runtime configuration, and API routing with a React + Vite single-page frontend that offers a streamlined create, library, and player workflow inspired by commercial tools. Songs, metadata, and cover images are stored using SQLite plus a simple filesystem layout under a local data folder, which keeps things easy to back up or move between machines.
The app targets personal or self-hosted setups on macOS and Windows, avoiding port 8000 by default and exposing configurable backend and UI ports. You can optionally plug in an OpenAI-compatible endpoint to auto-generate prompts, lyrics, and titles, and hook up local or remote cover-art pipelines like Fal, ComfyUI, or A1111 for visuals.
Environment variables let you point to your ACE-Step repo and checkpoints, tweak network binding, and prepare for future ACE-Step modes such as lego, extract, and complete, which already have placeholder UI slots to keep the layout stable as the ecosystem grows.
