Get ready for real users
The unsexy checklist between 'demo works' and 'I gave the URL to 50 people.'

Create a free accountWhat you'll have at the end
An app that won't embarrass you in front of real users on day one — sign-in works, mistakes are recoverable, errors don't dump stack traces, and you can spot a problem before your users tell you about it.
01
Who this is for
- Anyone whose 'demo' is about to become 'production'
- Builders sharing a URL outside their immediate team for the first time
- Solo operators who can't be paged at 2am because there's nobody else
02
How to frame the idea
Real users aren't smarter or dumber than you — they're just unsupervised. They'll click the back button mid-submit. They'll sign up with the same email twice. They'll paste a 9MB image into a text field. 'Production-ready' just means none of that takes the app down or eats their data. Build the boring stuff first, then ship.
03
What people actually build
Public form → real submissions
Your intake form has been demo-only. Now you're posting the link in a newsletter. What needs to be true before you click send?
Internal tool → external teammates
The app worked great for your team of 4. Now you're inviting a vendor. Different access, different patience, different attack surface.
Side project → first paying customer
You're charging money for the first time. Refunds, receipts, and 'sorry about that' need to be solved before, not after.
04
Tool choices, honestly
Lovable Cloud (built-in auth, errors, logs)
You want the basics — sign-in, error capture, audit — without picking three separate vendors.
Sentry / PostHog
You want richer error tracking and product analytics, and you already know how to read them.
Resend / Postmark
You're sending real transactional email (password resets, receipts) — don't ship those from a free Gmail account.
05
Prompts you can lift
Audit the error surface
Prompt by PromptlyDo™Walk through every form and every async action in this app. For each, tell me: what happens when the request fails? what does the user see? is the failure logged anywhere I can see it later? Flag any place that shows a raw error message, a blank screen, or silently swallows the error.
Lock the auth edges
Prompt by PromptlyDo™Review my auth flow end-to-end. Test that: signed-out users can't reach any protected page (test by URL, not just the menu); signed-in users only see their own data; password reset works and the reset link expires; signed-out sessions can't act on stale cached data. List anything missing.
Add a real error boundary
Prompt by PromptlyDo™Wrap the app in a top-level error boundary that catches anything I missed. Show the user a friendly 'something broke — we logged it' message with a way to navigate home. Send the error (with user id and route) to my logging pipeline.
Smoke-test the unhappy path
Prompt by PromptlyDo™Write a short manual QA script I can run before every release: sign up, sign in, try the main action, sign out, try the main action again (should fail), refresh mid-action, submit the form twice fast, paste a giant image. Tell me what 'pass' looks like for each.

What tends to break
- Errors that show a stack trace to the user. Looks unprofessional and leaks internals.
- No way to recover from a typo. The user submits a form, can't edit, can't delete, has to ask you.
- Sign-out doesn't actually sign out — protected pages still load from cache.
- Password reset emails that take 3 minutes (or land in spam) so users sign up again with a different email.
- No monitoring. The app's been broken for 6 hours; you find out from a customer email.
- Free-tier services that hard-cap at the worst moment (1,000 emails/day, 100MB DB).
07
What AI forgot to ask you
- Who do you page when it breaks at midnight? If the answer is 'nobody,' add status messaging users can read.
- What's the data-loss story? If you accidentally drop the table, what's the most recent backup — and have you tested restoring it?
- What happens when two users try to do the same thing at the same time?
- How will you know it's slow before users complain? Set a baseline now, not after.
- Are you GDPR / CCPA on the hook? Even a hobby project with 'delete my account' has obligations.
08
Before real users see it
- I tried to reach every page while signed out — none of them rendered protected data.
- I tried to view someone else's record by changing the URL — I got a clean not-found, not a leak.
- I submitted the main form with garbage input — I saw a clear, friendly error, not a crash.
- I refreshed in the middle of a save — no duplicate row, no orphan record.
- I have logs for the last 24 hours and can find an error by user id in under a minute.
- I have a daily DB backup and I've restored it once on a test instance.
- Transactional email lands in under 30 seconds and not in spam (I tested Gmail, Outlook, iCloud).
- I have a status message I can flip to 'we're aware, working on it' without redeploying.
09
Questions to sit with
- 1.What's the worst thing that can happen on day one — and have I tested that exact scenario?
- 2.If I get 100 signups in an hour, what breaks first? Cost, database, email quota, or me?
- 3.Am I shipping fast because I'm confident, or because I'm tired of looking at it?
- 4.Who's the one person I trust to use it before strangers do — and have I asked them yet?
Beginner safety net
Before real users see it — the short list.
Tick what's true. The unticked ones are your remaining work.

Before Real Users Checklist
The minimum bar before you put something in front of real humans. Not all of these are technical — most aren't.
