How to Deploy a Vibe-Coded App
Most vibe coding platforms give you a live URL the moment your app works, that part is one click and usually free. Deploying it properly, so it holds up under a custom domain, real traffic, and real data, is a separate step most people skip past without noticing. The short path: get the free preview link working first, run through your core flows like a real user would, then decide if you need a custom domain, a paid hosting tier, or a human review before you send the link to anyone other than a friend testing it for fun.
I'm Mahmoud Zalt, an AI systems architect running Sistava, where autonomous agents do real business work in production, which means "it runs" and "it's actually deployed properly" have to mean the same thing every day, not just on launch day.
The two kinds of "deployed"
There is a meaningful difference between having a live link and having a real deployment, and conflating the two is where most vibe coding launches go sideways.
- The free preview URL. Almost every vibe coding platform hands you one automatically, something like yourapp.platform.com. It is genuinely live, genuinely shareable, and totally fine for testing, demos, and a small circle of real users.
- A real deployment. Your own domain, proper handling of secrets and environment configuration, a plan for what happens when traffic spikes or a dependency updates, and someone having actually tested the flows that matter (signup, payment, anything that touches private data).
Shipping a personal tool or a prototype to friends? The free URL is the finish line. Shipping something you're calling a product, with real customers or their data? Treat the free URL as step one of several, not the end of the job.
Deploying a vibe-coded app, step by step
1. Get the one-click deploy working
Almost every platform in this space (Replit, Lovable, Bolt, and others) offers one-click deployment to a live URL. Do this first, before you polish anything further. Seeing your app actually live, not just running in a preview pane, changes how you test it.
2. Walk through every core flow yourself
Click every button. Fill every form with real-looking (not real) data. Confirm anything that should save actually persists after a refresh. This is the single highest-value 20 minutes you will spend before sharing the link with anyone.
3. Check what happens to secrets and keys
Never hardcode an API key or password directly into a prompt or into visible code. Most platforms offer a secrets or environment variable feature specifically so keys are not exposed in your app's source. If you are not sure where a credential ended up, check before you deploy, not after.
4. Decide if you need a custom domain
A subdomain is fine for testing and for tools you're using yourself. A custom domain (yourapp.com instead of yourapp.platform.com) signals a real product and is usually a paid-tier feature. Add it once you are confident the app itself is solid, domains are easy to point at something new later.
5. Plan for what happens after launch
Real deployment is not a one-time event. Who checks if it goes down? What happens if a change breaks something? For a personal tool, the answer can be "me, occasionally." For anything with real users, that answer needs to be a real plan, not an assumption.
Before you send the link to anyone but a friend
| Check | Why it matters |
|---|---|
| Every button and form actually works | A confident-looking bug is still a bug |
| No real passwords, keys, or personal data used in testing | What goes into a prompt or a test field can end up somewhere you didn't intend |
| Secrets are stored properly, not hardcoded | Exposed keys are the most common security failure in vibe-coded apps |
| Data actually persists (refresh and check) | Apps that "work" in the moment but don't save are a common silent failure |
| Someone besides you has clicked through it | You already know how to avoid your own app's rough edges; a stranger won't |
Frequently Asked Questions
Is the free URL a vibe coding platform gives me a real deployment?
It is a real, live, working deployment, and it's genuinely enough for a prototype, a personal tool, or sharing with friends. It becomes insufficient the moment you need a custom domain, expect real traffic, or are handling other people's data, at which point you want a more deliberate deployment plan, not just the default link.
Do I need a custom domain to launch?
Not to launch, no. A custom domain matters for credibility and branding once you're treating the app as a real product. For testing an idea or building something for personal use, the platform's default subdomain is completely fine.
What's the most common security mistake at deploy time?
Hardcoding an API key or password directly instead of using the platform's secrets or environment variable feature. It's an easy mistake to make while iterating fast, and an easy one to avoid by checking where your credentials live before you share the link.
When should I get a professional involved in deployment?
Once real users, payments, or private data are involved. A prototype deploying to a handful of friends does not need a security audit. A product you're charging for, or one handling anyone's personal information, does.
Live is easy, ready is a checklist
Getting a vibe-coded app live is usually one click. Getting it ready for real users is a short, specific checklist: test the core flows yourself, keep secrets out of your code, decide deliberately about a custom domain, and have a plan for after launch, not just for launch day.
The deployment chapter of The Vibecoder's Handbook goes through this in full, and it's free. When a launch is real enough that you want a professional set of eyes on it first, that's exactly what AI consulting is for.
