Lynx comes with full support for Umami, both standard tracking and events.

UMAMI_URL | The URL to your umami instance. |
For Umami to track links being used,
FORCE_FRONTEND_REDIRECT
will need to be set to true
. This may slightly increase redirect times.Variable | Description | Example |
---|---|---|
BACKUP | Wether to create backups or not. They will be in ./backups or /app/backups for Docker | true |
BACKUP_SCHEDULE | 0 * * * * | |
BACKUP_COUNT | How many backups to keep. 1 will make a backup file called backup.json, -1 will keep every backup. | 5 |
Variable | Description | Example |

FORCE_FRONTEND_REDIRECT | Use the frontend to redirect instead of express, useful for hiding embeds on discord for all your rickrolling needs | false |
