Building your app
Deploy
Deploying your app means copying its latest version onto a server on the internet, so anyone with the link can use it.
Also called deployment
Until you deploy, the changes you make exist only in your builder or on your own computer. Many app builders deploy for you when you press a publish button. Each deploy replaces what visitors see, so a broken change goes live too.
When this shows up
Example, not a real founder: you fix a typo on your sign-up page and ask a friend to check. They still see the old typo. The fix was saved in your builder but never deployed, so the live app did not change.
What to do next
Find the publish or deploy button in your builder and note when it last ran. Make one small change, deploy it, and open the live link in a private browser window to see that it shows.
