Before you publish your app: checklist

Last updated October 14, 2026

1. Preview or published version?

I opened the published link (not the preview) in a private or incognito window.I published again after my last change, and the published link shows it.

If something fails: Lovable preview works but the published site doesn’t · The published link doesn’t show my latest changes

2. Blank screens and errors

Every page opens, with no blank screen.I clicked every button and link at least once, and each one does something.Forms show a clear message when something is wrong, like an empty field.

If something fails: My app shows a blank screen · I clicked the button and nothing happened

3. Personal data

No names, emails or phone numbers are visible to people who shouldn’t see them.I tested with two accounts, and one can’t see the other’s data.No passwords or secret keys are written in the pages.What I save is still there after I reload the page and open it on another device.

If something fails: Could my app be exposing personal data? · My data disappeared when I reloaded the page

5. Phone layout

I opened the published link on a real phone, not only on a computer.Text is readable and buttons are easy to tap without zooming.Nothing is cut off, and I don’t need to scroll sideways.

If something fails: Prompt: make the app easy to use on a phone

6. Text and typos

I read every page once, slowly, looking for typos.Placeholder text, like “Lorem ipsum” or “Your title here”, is gone.Contact details, prices and opening hours on the page are correct.

If something fails: Prompt: review the app’s text

7. Credits and plan

I know which plan I’m on and how much of its credits or tokens are left.I know what happens when the free allowance runs out.

If something fails: I ran out of credits in the middle of my project · Lovable credits explained · Monthly cost calculator

8. Custom domain (optional)

Only if you bought your own address, like yourname.com.

My own domain opens the app, with https at the start of the address.

If something fails: Glossary: domain

9. Backup

I exported or synced the code (for example, to GitHub), if the tool offers it.I know where the version history is, so I can go back if something breaks.

If something fails: Glossary: GitHub

Frequently asked questions

Where are my ticks saved?

In your own browser, using local storage. They stay there if you close the page and come back on the same device and browser. Nothing is sent to us, and clearing your browser data erases them.

Do I need to check everything before publishing?

The items about personal data and the published link matter most, because they affect other people. The custom domain is optional, and the login items only apply if your app has login.

Something on the list failed. What now?

Each section links to the page about that problem, with the text to paste into the AI. Fix one thing at a time and test again the same way.
