StackBlitz WebContainer GitHub Deployment Log Routing

StackBlitz WebContainer and GitHub repository: deployment log routing

When a StackBlitz WebContainer template deployment fails, the goal is to determine whether build and deploy logs appear in the StackBlitz IDE terminal or preview console, only in the external deployment host, or in both.

StackBlitz can import a public GitHub repository into a WebContainer workspace, and an authenticated GitHub connection enables repository actions, but public documentation does not guarantee automatic sync, push, or redeploy behavior for every template.

Because WebContainer builds run in the browser tab, tab closure, memory pressure, or offline state can interrupt a build without server-side logs. Retention and access likely belong to the deployment target or template configuration.

Under what conditions do failure logs cross the IDE-GitHub boundary, and which party preserves them? Does an authenticated GitHub push to an imported repository trigger an automatic redeploy, and which OAuth scope controls that behavior?

WebContainer builds execute entirely in the browser tab, so failure logs only exist in the IDE terminal or preview console while that specific session remains open. Closing the tab, going offline, or hitting memory limits terminates the in-browser process and discards any build output — StackBlitz does not persist these logs server-side after the session ends.

Logs reach GitHub or an external deployment host only when the template explicitly forwards them (e.g., via commit status, check run, artifact upload, or a configured CI/CD webhook). A simple authenticated git push to the imported repository updates the remote but does not, by itself, trigger a WebContainer redeploy; that requires a separate repository webhook or CI integration.
