omnipaperEnvironment variables
The full reference for every environment variable the app reads at boot.
Environment variables cover deploy time wiring and secrets. Everything else (storage, OCR, AI, email) is configured in the UI. See Installation for the minimal set.
Required
| Variable | Description |
|---|---|
DATABASE_URL | PostgreSQL connection string. |
AUTH_SECRET | Signs auth sessions and cookies. Use a random 32 byte value (openssl rand -base64 32). |
ENCRYPTION_KEY | Encrypts credentials you store in the app (S3, OCR, AI, email passwords). Minimum 16 characters. Generate with openssl rand -base64 32. Keep it stable and backed up: if you change or lose it, stored secrets can no longer be decrypted and must be re entered in Settings. |
