Build a Remy app with Claude Code

The exact steps, top to bottom. Do the first block once on your machine. Do the second block for every app. Anything in a pink box is meant to be pasted straight into Claude Code.

First time only once per computer

About fifteen minutes. You only ever do this once.

  1. Install Git and Node.js

    Two free programs Claude Code needs. Windows: install Git for Windows and Node.js LTS from their sites. Mac: install Node.js LTS; Git is already there.

  2. Install Claude Code and open a folder

    Open a terminal (Windows: PowerShell; Mac: Terminal) and paste the line for your system, then make a working folder and start Claude Code.

    Windows: irm https://claude.ai/install.ps1 | iex Mac: curl -fsSL https://claude.ai/install.sh | bash mkdir remy-apps cd remy-apps claude
  3. Install the MindStudio tools

    Paste this to Claude Code. It installs the two tools every later step uses.

    Paste into Claude Code
    Install the two MindStudio tools with exactly this command: npm install -g @mindstudio-ai/agent @mindstudio-ai/local-model-tunnel . Then run "mindstudio --help" and tell me in one sentence whether it worked.
  4. Sign in to MindStudio

    In a terminal type mindstudio login and press Enter. A browser opens; pick your own name and click Continue. The page may then say "Connection failed"; ignore it, the terminal is the truth and says Authenticated. Your key is now saved; you never type it again.

Every app the whole loop

These five steps are the entire method. The first time, read the full guide for the detail behind each one.

  1. Make the app in Remy

    Go to app.goremy.ai, click New App, copy the long code between /apps/ and /edit in the address bar, and close the tab. Do not type in Remy's chat while Claude Code has the app.

  2. Let Claude Code download it

    Paste this, with your app id in place of the pink part.

    Paste into Claude Code
    Download my Remy app into a new folder here. The app id is PASTE-YOUR-APP-ID. Clone it from https://git.mscdn.ai/<app id>.git using HTTP Basic auth: username x, password my MindStudio key from ~/.mindstudio/config.json. Use an askpass script, never show or store the key, and set the app's name in mindstudio.json.
  3. Start the tunnel and open the preview

    In a terminal, go into the app's folder and run mindstudio-local. The first run shows a menu, not your app: press q and run mindstudio-local again. Then paste the line below to get the address to open.

    Paste into Claude Code
    The tunnel (mindstudio-local) is running for this app in another window. Find the http://127.0.0.1 address it serves the preview on (confirm the page contains __MINDSTUDIO__) and give me the link. If a first click errors with "protocol 'c:'" on Windows, apply the tunnel's pathToFileURL fix and tell me what you changed.
  4. Tell Claude Code what to build

    Describe the app or the change in plain English. Watch the preview; the tunnel picks up each save at once.

    Paste into Claude Code
    Build this app: describe what it should do. Test every change through the tunnel preview with realistic input before telling me it works, and show me what it returned.
  5. Publish it

    One message ships it. Live in about fifteen seconds at a public web address.

    Paste into Claude Code
    Publish this app: commit every change, push to origin main with the same Git auth as the clone, wait for the release (set WORKSPACE_DIR to this folder and MINDSTUDIO_API_KEY from ~/.mindstudio/config.json for that command), then fetch the public address and confirm it answers. Tell me: pushed yes/no, release status, address checked yes/no.

An app you already have

Any app in app.goremy.ai downloads and edits exactly the same way, however it was built. Start at step 6 with its app id.

An old drag-and-drop agent

These cannot be edited from Claude Code, only run: Run my MindStudio agent called NAME with this input…. The one exception is a custom screen or script inside the agent, handed over through the tunnel while the agent is open in the editor.

What it costs

Building this way barely touches your Remy balance, because Claude Code writes the code. Running an app costs only what its own AI calls cost; an app with no AI runs for free. Close Remy's chat editor while Claude Code works, or its builder builds in parallel and bills you.
