How to Make Your Vibe-Coded App Feel Like a Real Product

A user finds your app. They sign up, excited to try it. Then they wait for a welcome email that never comes. A few days later, they've forgotten about it. A week later, they couldn't tell you the name.

Meanwhile, Duolingo is guilt-tripping them into practicing Spanish. Notion is sending tips to help them get started. Airbnb is reminding them about that trip they browsed last week.

Every real product they use is in their inbox, onboarding them, nudging them, earning their attention. Your app? Silence.

That's the gap. That's why it feels like a toy.

The trap: adding legitimacy by adding code

So you try to fix it. You follow the tutorials. You sign up for Resend or SendGrid. You get an API key. You write an Edge Function. You add a sendEmail call after user signup.

And it works. So you add another one for password resets. Another for order confirmations. Another for trial reminders.

Now you have sendEmail scattered across ten different files. Which emails are actually being sent? How do you know if the re-engagement email is working? Are you going to ask your AI assistant every week, "How is the welcome email performing?"

The welcome email fires twice because of a race condition. The re-engagement script breaks and you don't notice for a week. The AI assistant you've been vibing with starts getting confused because your prompts now include notification logic alongside your actual product.

Here's the trap: you solved the silence problem by creating a visibility problem.

One or two emails feels manageable. Ten emails scattered across your codebase? That's not a notification system. That's a mess you can't see, can't measure, and can't improve.

What legitimate apps do differently

I've been building software for a long time. Startups, big companies, side projects. And there's a pattern I've seen over and over:

The apps that feel legitimate aren't the ones with the most code. They're the ones with the right separation of concerns.

Your app has a job. Maybe it's a marketplace, a dashboard, a tool, a community. That's what your code should be about.

But making users feel engaged? Bringing them back? Communicating professionally? That's not your app's job. That's a different job entirely. We call it the growth layer.

Real products don't mix these together. They separate them. And that separation is exactly what makes them feel legitimate.

The second pane of glass

Think about how you work. You don't build your product and your growth strategy in the same tool. So why would you put them in the same codebase?

Here's how I think about it:

Pane 1: Your editor. Lovable, Cursor, VS Code, Bolt: wherever you build your app. This is where your product lives. It should be focused, clean, and entirely about what your product does.

Pane 2: A separate tool for your growth layer. This is where notifications live. Welcome emails. Re-engagement. Lifecycle messaging. All the "what happens after" stuff that makes your app feel like someone's home.

You don't cram both into the same codebase. You use the right tool for each job.

At Dreamlit, this is exactly what we built. Your app stays in your editor. Your growth layer lives in Dreamlit. Two panes of glass. Each focused on its job.

Why vibe coders specifically need this

When you're vibe coding, you're having a conversation with AI about what you want to build. That conversation works best when it's focused.

"Build me a marketplace where users can list items" is a clear prompt.

"Build me a marketplace where users can list items, and also send them a welcome email when they sign up, and remind them if they haven't listed anything after 3 days, and notify them when someone favorites their listing, and handle email errors gracefully, and..." is not.

The more you pack into your app, the harder it is to vibe code effectively. The AI has more to keep track of. The codebase gets harder to reason about. Small changes have unexpected ripple effects.

By keeping the growth layer out of your app, you keep your app simple enough to vibe code forever. And that's what keeps it maintainable. That's what lets you keep improving it. That's what makes it feel like a real product over time.

Your database already knows

Here's the technical insight that makes this work without adding code to your app:

Your database is your source of truth. When a user signs up, that's a row in your users table. When they log in, that updates last_login. When they make a purchase, that's a row in orders.

All the information you need to send the right email at the right time? It's already there.

You don't need to tell an external service what happened. You don't need webhooks. You don't need API calls from your app.

Dreamlit watches your database directly. When something changes, we see it. Your app doesn't need to know we exist.

This means:

• No notification code in your app
• No API keys in your codebase
• No Edge Functions to debug
• No "why didn't this email send?" debugging sessions

Your app stays clean, focused, and vibe-code-friendly.

The path to legitimacy

The apps that feel real aren't the ones with the most features. They're the ones that communicate like real products.

And the way to communicate like a real product isn't to scatter email code throughout your app. It's to build a proper growth layer: separate from your app, focused on its job, easy to iterate on without touching your codebase.

Your vibe-coded app already does its job. Now give it the layer that makes it feel like a real product.

That user who signed up and forgot your app's name? With Dreamlit, they get a welcome email. Three days later, a check-in. A week later, a nudge if they haven't come back. All without touching your code.
