Download nonoha Hub

The app is free. Downloading engines, plugins and workspaces from nonoha Cloud and publishing need an account and a subscription (¥600 per month, tax included).

Installing

macOS: open the disk image and drag nonoha Hub to Applications. The app is not notarized by Apple yet, so macOS stops it the first time you open it: then go to System Settings → Privacy & Security and choose Open Anyway.
Open nonoha Hub once before you use the nonoha command bundled with it from a terminal or an AI agent: allowing the app also allows the command.
Windows: run the installer. If SmartScreen warns about an unknown publisher, choose More info → Run anyway.

Build with AI

nonoha Hub includes the nonoha command. Open a workspace and choose Build with AI to work on it with an AI coding agent such as Claude Code, Codex, Gemini CLI or Cursor: the agent writes nodes and the web app, you run them in the app.

Uninstalling

macOS: move nonoha Hub from Applications to the Trash. Windows: Settings → Apps → nonoha Hub → Uninstall. Your workspaces, downloads and settings stay in the .nonoha folder of your home folder; delete it to remove them too.
