  3. Click Deploy to migrate and deploy to production
The extension automatically:
  • Detects which builder platform you’re on

  • Creates a migration in your Nometria account
  • Deploys a staging preview

​
On GitHub

When visiting a GitHub repository page:
  1. Click the Nometria extension icon
  2. Click Import & Preview to:
    • Import the repo into your Nometria account
    • Deploy a staging preview
  3. If GitHub OAuth isn’t connected, you’ll be prompted to connect

​
From the Popup

Click the extension icon anywhere to:
  • View all your apps and their status
  • Quick-deploy or resync any app
  • Access the Nometria dashboard

How It Works

Builder (Base44/Lovable/Manus)
  ↓ Content script detects platform
  ↓ Adds Preview/Deploy buttons
  ↓ On click: exports code (API or ZIP)
  ↓ Uploads to Nometria API
  ↓ Creates migration + staging preview
  ↓ Shows preview URL in popup

​
Permissions

The extension requires:
  • activeTab — to detect which builder platform you’re on
  • storage — to save your login session
  • downloads — to export ZIP files from builders
  • identity — for OAuth login flow
Host permissions are limited to Nometria domains and supported builder platforms.

​
Troubleshooting

“Not logged in” after install: Click the extension icon → Login → sign in at nometria.com Extension doesn’t appear on builder site: Refresh the page. If it still doesn’t appear, check that the extension is enabled at chrome://extensions. Preview fails: Check that your Nometria account is active at nometria.com/dashboard. Need help?
