Build · ~5-10 min This step needs nothing from you. The header flips to Provisioning your stack, the installer takes over, and you can walk away. While it runs, it builds and verifies your whole stack:
  • Your database, with the scheduled jobs that keep the machine ticking (billing included).
  • Your app, built and deployed to your Vercel account.
  • Every webhook receiver (each one answers a signed test) and the channel your notifications ride on.
In the Setup log, each step gets a yellow checkmark as it passes, with a note on what was just verified.
Build: the We build your stack column, twelve rows earning yellow checkmarks.
Checkpoint: all twelve build steps checked off; the run stops at install, waiting for you.
You can’t break the run. Close the laptop or lose Wi-Fi and it picks up where it left off when you reopen. If a step fails, click Retry. Still stuck? Email support@opensubs.com with your run ID (top of the installer).
