Where to Host Your Vibe-Coded App

Your app works. It’s sitting there, live, at a web address your AI tool handed you for free, and for the first time you can send someone a link instead of a screen recording. The hard part is supposedly over.

But then a more practical question arises: where should this app actually live? The free address it came with is one option, but it isn’t the only one, and it’s rarely the one you want to stay on for long (if at all).

So here’s a plain-English guide to hosting your vibe-coded app: what hosting actually means, whether the free tiers are good enough, how to tell when you’ve outgrown them, and what your real options are once you do.

What “Hosting” Actually Means

When your app runs on your laptop, only you can see it. Hosting means putting that app on a computer that’s always on and connected to the internet, so anyone with the link can reach it. That computer is usually called a server, and you rent it (or a slice of it) from a hosting provider.

A few words you’ll keep running into, in plain terms:

• Deploying is the act of pushing your app onto that server.
• Hosting is where the app lives afterwards and what keeps it running, day and night.
• A domain is the human-friendly address (mycoolapp.com) people type in the browser.
• Scaling is how your app handles more people using it at the same time.

Should You Start With the Free Tiers? (Lovable, Netlify, Vercel)

Most vibe-coded apps launch on a free tier by default. Your app comes with an address like yourapp.netlify.app, yourapp.lovable.app, or yourapp.vercel.app.

It costs nothing, and is live the moment you finish building. For trying an idea out or showing a handful of people, that’s genuinely fine.

For anything you want people to take seriously, it isn’t…and there are two reasons why.

You Started Free. Is It Time to Migrate?

You don’t need to track server metrics to know you’ve outgrown a free tier. The signs are things you’ll feel as the owner:

• The app gets slow or unreliable under load. Pages that were instant now lag when a few people use it at once, or visitors hit errors at busy moments.
• You’re bumping into limits. You’re getting “you’ve exceeded your quota” emails, or features stop working partway through the month.
• You need things the free tier won’t give you. A proper database, file uploads, scheduled jobs, or background processing.
• The bill is creeping up anyway. You’ve stacked enough paid add-ons onto the “free” plan that you’re now paying real money for a setup that still has training wheels.
• You want control you don’t have. You need to choose where your app runs, meet a compliance requirement, or stop being locked into one vendor’s way of doing things.

One of these on its own is usually manageable. Two or three together is the app telling you it’s ready for a real home.

Your Real Hosting Options

Once you decide to move beyond a free tier, these are the main hosting options worth considering.

For most founders coming off a free tier, a managed app platform with a custom domain is the answer, and it will stay the answer for a long time. It gives you a real, professional home without asking you to become a system administrator overnight.

At the far end of the hosting spectrum are the big three: AWS, Azure, and GCP. The names carry enough weight that it can be tempting to start there just to look the part. Resist it. Setting them up properly takes real expertise, and the usage-based pricing system can become really expensive really quickly.

Do I Need Kubernetes or Something Advanced?

At some point you may have asked your AI tool how to deploy your app and gotten back a confident, elaborate plan: an auto-scaling Kubernetes cluster, load balancers, container orchestration, a diagram with more boxes than your app has features.

For most founders still in the early stages, this is overkill. Kubernetes is a system for running an app across many servers at once and automatically adding or removing capacity as demand shifts.

It solves problems of scale and complexity most apps don’t have at the beginning, and it brings a maintenance burden that quietly becomes a second job.

Think of it like this: Building it in the early days is like buying a freight depot to ship your first ten parcels.

That said, there are real situations where this kind of setup earns its keep:

• You have genuine technical depth on the team and can run it without it running you.
• You’re bringing in engineering help — say, onboarding a consultancy to take the app to the next level.
• You’re expecting rapid, sustained growth that a single server realistically can’t absorb, and the cost of being unprepared outweighs the cost of the complexity.

If none of those describe you today, file Kubernetes (or any other advanced deployment model) under “maybe later.”

A Simple Decision Framework

Strip away the brand names and the hosting question comes down to one honest read of where you actually are. Find the row that sounds most like you:

The rule underneath the whole table: host as simply as your app allows, and only move up a level when the app itself starts pushing back.

Wrapping Up

Hosting feels like a high-stakes, one-way decision, which is why so many founders either freeze or over-build. It’s neither.

A free tier is an okay place to begin but a poor place to stay. A managed platform with a real domain is where most apps belong for a long, productive stretch.

And the heavy machinery (big cloud, Kubernetes, dedicated servers etc.) is something you grow into deliberately, not something you reach for from the very off.

Match the home to the moment, watch for the signs that you’ve outgrown it, and you’ll spend your money and attention where they actually matter: the product.
