View build & runtime logs

Goal: See what your app printed during build and at runtime.

Prerequisites:

• An app with at least one deployment.

Build logs

1. Open the app and go to Deployments.
2. Click a deployment.
3. The Build logs panel streams the build in real time. After completion you can scroll through the full log.

Runtime logs

1. From the app detail page, open the Logs tab.
2. The panel streams the running container’s stdout and stderr.
3. Use the Pause button to freeze scrolling, and Resume to follow the tail again.

Verify

• Running console.log(...) or print(...) in your app produces a line in the Runtime logs panel within seconds.

Notes

• Build logs are stored in Uploy’s database and kept alongside their deployment row indefinitely (subject to deployment retention).
• Runtime logs are streamed live from the running container’s stdout/stderr — there is no centralised log store yet, so historical lines older than the current container restart are not retrievable. Centralised retention is on the Phase 5 hardening roadmap (see docs/known-technical-debt.md).

Next steps

• Restart and stop an app
