Vercel has extended the maximum session duration for Vercel Sandboxes from 5 hours to 24 hours, available now on all Pro and Enterprise plans.

The full documentation covers pricing limits and the persistent sandbox configuration, both worth reading if you are running anything close to the old 5-hour ceiling.
