Installation

Installing Claunity takes under 5 minutes. You import one Unity package — the desktop app downloads and installs itself automatically with a single button click.

What you need

Unity 2021.3 LTS or newer. An API key from Anthropic (Claude API) — or a Claude Code subscription (no key needed). See AI Providers.

Step 1 — Import the Unity package

  1. In Unity, go to Assets → Import Package → Custom Package…
  2. Select the downloaded Claunity.unitypackage
  3. Make sure all items are checked → click Import
  4. Wait for Unity to recompile (progress bar in the bottom-right)
  5. Open Window → Claunity — the panel appears

Coming soon — Unity Asset Store

Once Claunity is on the Asset Store, you'll just click Import in Package Manager — no manual download needed.

Step 2 — Download the desktop app (one click)

When you open the Claunity panel for the first time, it automatically checks whether the desktop app is installed.

If it's not installed yet, you'll see the welcome screen with a single button:

Claunity

CLAUNITY

Claunity App not installed

Free download · One-time setup · ~50 MB

⬇   Download Claunity App

Click Download Claunity App. Claunity will:

  1. Fetch the latest version info from the update server
  2. Download the correct installer for your platform (Windows / macOS / Linux)
  3. Run the installer automatically — no manual steps
  4. Launch the desktop app in the background
  5. Connect to it and open the main UI

The whole process takes about 30–60 seconds depending on your internet speed. A progress bar is shown throughout.

Already installed?

If the desktop app is installed but not running, the button will say ▶ Start Claunity instead. Click it — the app starts and connects automatically. If it's already running, Claunity skips the welcome screen entirely and opens straight to the main UI.

Step 3 — Enter your API key

  1. Click the ⚙ settings icon in the top-right of the panel
  2. Under AI Source, choose API Key or Claude Code
  3. If using API Key — select your Provider and paste your key
  4. Pick a Model from the dropdown
  5. Click Save Settings
  6. Click Test Connection to confirm it works

Recommended model

Start with claude-sonnet-4-6 — best balance of speed, quality, and cost. See AI Providers for a full comparison.

You're ready

Everything is working when you see:

  • A green dot and "Connected" in the Claunity header
  • Mode tabs at the top: VIBE / PROJ / TEST / BUILD
  • The chat input is active and ready

If you see a red dot or an error, check the Troubleshooting guide.
