Environment variables are how your app gets secrets (API keys, database URLs) without baking them into your source code. Nometria encrypts all variables at rest and injects them at runtime.

​
Add environment variables

On the configuration screen before your first deploy, scroll to Environment Variables and add your key/value pairs.

​
Common variables by framework

VITE_SUPABASE_URL=https://xxxxxxxxxxxx.supabase.co
VITE_SUPABASE_ANON_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
Vite exposes variables prefixed with VITE_ to the browser bundle. Never put secret keys in VITE_ variables — use them only for public anon keys or public URLs.
# Public (exposed to browser)
NEXT_PUBLIC_SUPABASE_URL=https://xxxxxxxxxxxx.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

# Server-only (never sent to browser)
SUPABASE_SERVICE_ROLE_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

# Public key — safe to expose to browser
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_live_...

# Secret key — server-only, never prefix with NEXT_PUBLIC_ or VITE_
STRIPE_SECRET_KEY=sk_live_...
STRIPE_WEBHOOK_SECRET=whsec_...

# Server-only — never expose to browser
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...

​
Environments

Nometria supports separate variable sets for staging and production:
  • Staging — your *.nometria.com URL or a staging.yourcompany.com subdomain
  • Production — your primary custom domain
Variables set at the project level apply to both. Override individual variables per environment:
  1. Settings → Environment Variables → toggle Per-environment override
  2. Set the staging value and production value separately
This lets you use test Stripe keys on staging and live keys on production with zero code changes.

​
Security

  • All variables are encrypted at rest using AES-256
  • Variables are never logged in build output or deploy logs
  • Values are masked in the dashboard after saving (you can only overwrite, not view)
  • Variables are injected as true environment variables at container startup — they are not written to disk
Never commit secrets to your Git repository. Nometria reads secrets from the encrypted variable store, not from .env files in your repo.

​
Importing from .env files

If you have a local .env file, you can bulk-import it:
  1. Settings → Environment Variables → Import .env
  2. Paste the contents of your .env file
  3. Review the parsed variables and click Import
Nometria strips any # comments and blank lines automatically.
