Data and access From the checklist

Row Level Security is enabled on every table

Why it matters
Without RLS, anyone with your public key can read or change rows in that table.
How to check
In Supabase, open Table Editor or Authentication → Policies. Every table should show RLS as enabled.
How to fix
Ask your AI builder, then review the policies it creates.
Ask Lovable
Enable Row Level Security on every table and add policies so users can only read and edit their own rows.

What you get

60 practical checks

Data and access, sign-in, payments, mobile, accessibility, SEO, legal, and more.

Clear explanations

Why each item matters and how to check it yourself, in plain language.

Prompts for your AI builder

Know exactly what to ask Lovable, Claude Code, or Cursor to fix each gap.

A launch-day plan

A step-by-step order for the day itself, so nothing is left to memory.

The problem

Find the gaps before your users do.

Working is not the same as ready. AI builders get you to a working app quickly. The gaps that remain are often hard to see from the inside, because you already know how everything is meant to work. These are the ones that come up most often.

Data that is more open than you think

Tables without Row Level Security can be read by anyone with your app's public key.

Emails that never arrive

Default email senders are meant for testing. Real users may never receive their confirmation link.

Links that point to the wrong place

Password reset and sign-up links can still lead to a preview URL instead of your live site.

Pages that break on a phone

A layout that looks fine in a desktop preview can hide buttons or scroll sideways on mobile.

Blank link previews on launch day

Without the right tags, your launch post shows no title or image when it is shared.

No clear way to get help

When something goes wrong, users need to know how to reach you, and you need to know it happened.

The checklist

Know what to check. Know how to fix it.

60 checks across ten areas, written from real launches with AI builders. Each one explains why it matters, how to check it yourself, and how to fix it, including what to ask your AI builder.

  1. Stage 1 of 4 · 19 checks

    Lock the doors

    Make sure your data, sign-in, and payments work for real users, not only for you.

    • Data and access3 free3 Pro

      Who can read and change your data, and where your secret keys end up.

    • Sign-up, sign-in, and email3 free4 Pro

      Confirmation and reset emails that arrive, and link to your live site.

    • Payments2 free4 Pro

      Live keys, live webhooks, and what happens when a payment fails. If you take payments.

    Sign-up, sign-in, and emailFree check

    Auth redirect URLs include your live domain

    Why it matters
    Confirmation and password reset links can point to a preview URL or localhost, and fail for real users.
    How to check
    Sign up with a new email on your live site and click the confirmation link.
    How to fix
    Set the site URL to your live domain, and add it to the allowed redirect URLs.

  2. Stage 2 of 4 · 13 checks

    Make it work for everyone

    Walk through your app as someone who has never seen it, on a phone and with a keyboard.

    • Product and user journeys1 free5 Pro

      The first five minutes for a new user, plus empty, loading, and error states.

    • Mobile and accessibility7 Pro

      Real phones, tap targets, keyboard use, labels, contrast, and alt text.

    Product and user journeysFree check

    The main journey works for a brand-new user

    Why it matters
    You know how your app is meant to work. A new user doesn't, and the first five minutes decide whether they stay.
    How to check
    In a private window, go from landing page to sign-up to the main action, without using anything you already know.
    How to fix
    Note every point where you hesitated or hit an error. Fix the biggest one first, then repeat.

  3. Stage 3 of 4 · 14 checks

    Get found and trusted

    Give people, search engines, and social posts a clear picture of what you made and who is behind it.

    • Content, SEO, and sharing1 free4 Pro

    • Support and contact1 free3 Pro

      A way to reach you that works, and answers ready for the first questions.

    Content, SEO, and sharingFree check

    Link previews look right

    Why it matters
    Most social platforms read only the page's first HTML. Without Open Graph tags, your launch post shows a blank or generic preview.
    How to check
    Paste your URL into a social post draft or a link preview tool.
    How to fix
    Add a title, a description, and a 1200 × 630 pixel share image as Open Graph tags.

  4. Stage 4 of 4 · 14 checks

Made for

Made for people who ship with AI.

Founders building with AI

You built it by vibe coding with Lovable, Bolt, or Claude, and didn't write every line yourself. Each fix tells you what to ask your AI builder.

Indie hackers

You're preparing a SaaS or web app launch and want a fast, opinionated list without padding.

Freelancers and agencies

You hand sites over to clients and want to catch the gaps before they do. Run the same checks on every client project.

Most AI-built apps are not broken. They are unfinished in ways that are hard to see from the inside. After building and launching with Lovable, I kept noticing the same gaps, so I put my launch checklist into one place.

How it works

What Check and Launch does, and what it doesn't

Check and Launch is guidance, written for people who didn't write every line of their app. You stay in control of your app and your information.

What it does

  • Gives you a clear list of common launch gaps, with why each matters, how to check it, and how to fix it.
  • Tells you what to ask your AI builder, so you can fix things without writing code.
  • Helps you hand the checks to your own AI builder, then explains what it reports in plain language.

What it doesn't do

  • It doesn't scan or test your app automatically. You or your AI builder does each check.
  • It never asks for access to your code, database, or accounts.
  • It doesn't certify that your app is secure, compliant, or ready. It's not a security audit or legal review.

Your information

  • The free self-check runs in your browser. Your answers aren't sent or stored.
  • The app saves your projects in your browser. This site and the app make no AI calls, and nothing you enter is sent to us or to an AI provider.
  • Payhip handles payments. If you join the waitlist, your email is only used to tell you when Pro is ready.

FAQ

Common questions

Something else? Get in touch.

I didn't build with Lovable. Is this still useful?

Yes. Most checks apply to any web app. The Lovable and Supabase sections include specific settings; if you use Bolt, Claude, or another builder with a similar stack, the same principles apply.

I'm not technical. Will I understand it?

Every check is written in plain language. Where a fix needs a change to your app, it suggests what to ask your AI builder to do.

Is this a security audit?

No. Check and Launch helps you find common launch problems. It is not a penetration test, security audit, or legal review, and it cannot guarantee your app is secure or compliant.

Do you need access to my code or database?

No. Check and Launch never asks for access. You, or your own AI builder, do each check, and Check and Launch never sees your app's code.

I build sites for clients. Can I use it with them?

Yes. Pro covers your own client projects, and Agency adds unlimited client projects and a branded client report. Please don't resell or share the checklist itself.

Is it a subscription?

No. Pro and Agency are one-time purchases. You pay once for the version and features described when you buy.

Will I need an account?

No. You'll unlock Pro with a licence key from your purchase email. There's no password, and your projects stay in your browser.

What if it isn't useful to me?

For Pro and Agency, get in touch within 14 days of purchase and you'll get a full refund. See the refund policy.
