Logs

Last updated 04 November 2026

The Logs tab shows what your app writes to its output (stdout and stderr), from all its deployments. dudbox keeps 3 days.

• Live shows new lines as your app writes them.
• Last 15 min, Last hour, Last 24 h, Last 3 days show older lines.
• Pick one deployment to see only its lines. This helps when a new version does not start.

The build log of a deployment is not here: click the deployment on the Deployments tab, then Build logs. Runtime logs there shows the lines of that deployment only.

dudbox does not mask secret values in app logs. Your app writes what it writes, so do not print secrets.

Scripts and agents can read logs with the API. See Logs in the API.
