How to share an app you built with AI (safely, without leaking your code)

The moment you want to share — and the wall nobody warned you about

Here's the sequence almost every non-developer hits.

You describe an app to Lovable or Bolt or v0. After some back-and-forth, it works. You're genuinely proud of it. Then comes the obvious next step: show someone. Your client who's paying for it. The cofounder who needs to sign off. The investor who asked for "a quick look." Your first few users.

So you copy the preview link the builder gives you, paste it into a message, and hit send.

That's where it quietly goes wrong. The link points to something like your-app.lovable.app — a builder subdomain with someone else's branding on it. By the time your client opens it three hours later, the app has gone to sleep and shows a loading spinner or an error. Or the preview has expired entirely. Or — and this is the one nobody mentions — the link is wide open: anyone who gets it can poke around, see data that shouldn't be public, and in some setups even pull the source.

You built something good. The way you shared it made it look unfinished, broken, or careless. None of which is true.

What "sharing" actually means (it's four different things)

"Share my app" sounds like one task. It's really four, and they have different requirements.

Show a client or stakeholder. One person, needs to look polished, needs to work the moment they click — which is usually not the moment you sent it. The enemy here is a sleeping app and builder branding.

Collect feedback from a small group. A handful of people clicking around over a few days. Needs to stay live the whole time, and you probably don't want it indexed by Google or found by strangers. The enemy here is an expiring link and zero access control.

Demo to an investor. High stakes, often live on a call, sometimes on their own time afterward. Needs a clean URL (ideally your own domain — app.yourstartup.com reads very differently from app.bolt.host) and absolutely cannot break mid-demo.

Hand it to real users. Now it's not "sharing," it's shipping. Needs everything above plus reliability and a domain people can trust enough to sign up on.

The preview link your AI builder hands you is built for none of these. It's built for you to check your work while you're building. The instant you send it to someone else, you've taken a tool out of context.

The default options — and exactly why each one falls short

Most non-developers reach for one of these four. Here's where each breaks.

The builder preview link. Branded subdomain, sleeps on inactivity, sometimes expires, often publicly accessible. Fine for a quick "does this look right?" to a friend. Wrong for anyone whose opinion matters.

Download the ZIP and send it. Now you've handed someone your raw source code, and they can't even run it without a developer setup. You've simultaneously over-shared (the code) and under-delivered (nothing they can actually open). This is the worst of both worlds and yet people do it constantly.

Screen-share on a call. Works for a live demo, useless for "send it over so I can look later." And the person can't touch it themselves, which is half the point of a demo. It also ties the app's existence to your availability.

Ask a developer to "just put it online." This is the wall the whole category of non-developers keeps slamming into. You don't have a developer. Or you do, and they're busy, and now your two-day build is stuck behind someone else's backlog. The entire reason you used an AI builder was to not need this step.

The pattern: every default option forces you to choose between looks unfinished, leaks your code, or needs a developer. You shouldn't have to choose any of them.

The four things a shareable app actually needs

Strip away the noise and a genuinely shareable app needs exactly four properties.

1. A stable, always-on URL. It works when your client clicks it, not just when you do. No sleeping, no spinning up, no "try again in a minute." If the person you're trying to impress sees a loading error, the app failed before they ever saw it.

2. A clean address — ideally your own. app.yourbusiness.com signals "real product." A builder subdomain signals "weekend experiment." For clients and investors, this difference is not cosmetic; it's the difference between being taken seriously and not.

3. Access control. Not everyone with the link should get in. A password, or a private link that isn't indexed and isn't guessable, so your half-finished feedback build doesn't end up in a Google search or in front of a competitor.

4. Your source stays yours. When you deploy properly, you ship the built app — the thing that runs in a browser — not the source code behind it. The person viewing it sees a working product, not your files, not your API keys, not your database structure. This is the part the ZIP-and-send crowd gets catastrophically wrong.

Notice none of these four require you to learn DevOps or hire anyone. They just require a deploy step that's built for non-developers — which is the gap livemy.app exists to fill.

How to share your AI-built app safely (about 3 minutes)

Whether you built in Lovable, Bolt, v0, Cursor, or Replit, the shape is the same: get the code out of the builder, deploy it once, share the real URL. Here it is end to end.

Step 1: Get your app out of the builder

In your builder, export the project — usually Export → Download ZIP, or push to GitHub via the built-in integration. Lovable, Bolt, and v0 all produce a standard React/Vite project. You don't need to understand the code. You just need the export.

Step 2: Sign up at livemy.app and upload it

Go to livemy.app, click Start free (no credit card). In the dashboard, click New project → Upload archive and drop the ZIP, or Connect repo if you pushed to GitHub. livemy.app detects the framework and configures the build for you — there's nothing to set up by hand.

Step 3: Add your environment variables (if your app has a backend)

If your app talks to Supabase or any API, paste the keys under Project Settings → Environment Variables (for Lovable apps that's usually VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY). This is what keeps your keys server-side and out of the shared link. Skip this step if your app is purely frontend.

Step 4: Deploy and get a real URL

livemy.app builds the app and gives you an always-on your-app.livemy.site URL in a couple of minutes. This URL doesn't sleep, doesn't expire, and shows a working product — not your source. You can share this as-is, and it already beats every preview link.

Step 5: Lock it down — password or private link

For client and feedback shares, turn on access protection so only people you've given the password to can open it. Now you can send the link without worrying that it ends up indexed, guessed, or forwarded to the wrong person.

Step 6: Put it on your own domain (optional, about 5 minutes)

Click Add custom domain, paste app.yourbusiness.com, and update one DNS record at your registrar (Namecheap, GoDaddy, Cloudflare — all the same idea). SSL is automatic. Now your investor sees your domain, your HTTPS padlock, your product. Not a builder's branding.

That's the whole flow. Stable URL, your domain, access control, source kept private — the four things that actually matter, none of which needed a developer.

Keeping your source code private — the part people miss

This deserves its own callout because it's the most expensive mistake.

When you deploy an app the right way, the host serves the compiled, built version — the HTML, CSS, and JavaScript a browser runs. Your original source files, your server-side keys, your database schema: those stay on the server and never go to the visitor. The person you shared with sees a working app and nothing else.

When you instead email someone a ZIP, you've handed over the entire source — every file, often including config with API keys, and a clear map of how your app works. For a client you don't fully trust yet, or anyone you're pitching, that's a real exposure. And ironically they still can't open the app, because a ZIP of source isn't a running product.

Deploy, don't send files. It's safer and more impressive at the same time.

FAQ

How do I share a Lovable app without the Lovable branding?

Export the project and deploy it on your own host. The preview .lovable.app URL carries Lovable's branding and requires the Pro plan to remove; deploying the export to livemy.app gives you a clean URL (or your own domain) with no third-party branding. Full walkthrough in How to host a Lovable app outside Lovable.

Can I password-protect an app I built with AI?

Yes. AI builders' preview links generally don't offer real access control, but once you deploy the app you can put it behind a password or a private link. This is the right way to share a feedback build or a client preview without it being publicly accessible.

Will sharing my app expose my source code?

Not if you deploy it. A proper deploy serves the built app to visitors and keeps the source on the server. The exposure happens when people send a ZIP of the source instead — that hands over every file. Deploy and share the URL; never send the code itself.

My preview link keeps going to sleep — how do I stop that?

Preview environments on most AI builders sleep after inactivity to save resources, which is why your client often hits a dead link. Deploying to an always-on host removes the sleep behavior so the app is live whenever someone opens it. On livemy.app, the Maker plan gives you a custom domain and a 99.5% uptime SLA for sharing for real.

Do I need my own domain to share an app?

No, but it helps for anything high-stakes. A clean deployed URL is already a big upgrade over a builder subdomain. Your own domain (app.yourbusiness.com) is the final polish that makes a client or investor take the product seriously — and it takes about five minutes to connect.

What's the fastest way to share an app with a client right now?

Export from your builder, upload the ZIP to livemy.app, deploy, turn on password protection, send the link. Roughly three minutes, no developer, and it works when they click it instead of when you do.

Share it like it's real — because it is

You did the hard part. Don't let a preview link undercut it. Export your app, deploy it once, and send a real URL — always-on, on your domain, password-protected, with your source kept private.
