Firebase env helper
Paste the config object from the Firebase console to get Next.js or Expo environment variables, or a service account key to get both halves of the env ladder — a file path for local development and the same credential inlined for production. Runs entirely in your browser.
Everything runs in this tab. What you paste is never uploaded, logged, or stored.
Client config
The firebaseConfig object from the Firebase console, as public environment variables.
Service account
An admin key, as both halves of the env ladder: locally the SDK reads the file that GOOGLE_APPLICATION_CREDENTIALS points at, and in production it falls back to the same credential inlined as GCP_SA_JSON. Keep the file itself out of the repository.
