Runtime logs
Stream stdout and stderr from your server's active deployment.
The Runtime logs tab streams runtime output — everything your server writes to stdout and stderr — from the active healthy deployment of the selected environment.
Runtime vs build logs
There are two kinds of logs in Manufact Cloud:
| Type | Where | What it contains |
|---|---|---|
| Runtime logs | Runtime logs tab | Your server's output while serving traffic |
| Build logs | Deployments → deployment drawer | The build pipeline output for one specific deployment, per phase |
If the Runtime logs tab is empty, check that the selected environment has a deployment in the running state — logs only stream from a live deployment.
Tips
- Use the environment selector in the header to view logs for a preview branch instead of production.
- A tail of recent runtime logs is also shown on the server Overview page under the active deployment card.
- Log output is the fastest way to debug tool errors surfaced in Gateway Requests: find the failing request there, then match its timestamp here.
