How Do I Share My App With Someone Else?

You built something. It works on your laptop. You are genuinely pleased with it. Now someone wants to try it — a friend, a colleague, a potential user — and you have absolutely no idea how to get it in front of them. You cannot send them a file. You cannot email them your laptop. And copy-pasting the code at them is not going to help unless they know exactly what to do with it, which they probably do not.

This is the moment most vibe coders hit a wall they did not expect. Here is exactly what your options are — and which one to try first.

Why You Cannot Just Send a Link Yet

When your app is running on your laptop, it lives at localhost — your machine pretending to be a server. That address only works on your computer. When someone else tries to visit localhost:3000 they are looking at their own machine, not yours. There is nothing there.

To let someone else use your app, it needs to live somewhere on the internet that anyone can reach — a real server with a real address. That is what hosting means. And getting your app hosted is much more achievable than it sounds.

If You Built a Web App: Start With Vercel

A web app — something with a visual interface that runs in a browser — needs to be hosted somewhere with a public URL.

Start with Vercel. Vercel is a hosting platform specifically designed for web apps — it takes your code, runs it on their servers, and gives you a public URL that anyone in the world can visit. It is free to start, takes about ten minutes to set up, and works with almost every type of web app.

Here is the process:

1. Put your code on GitHub if it is not there already — here is how to do that
2. Go to vercel.com and create a free account
3. Click "Add New Project" and connect your GitHub repository
4. Click Deploy

Vercel detects what kind of app you have built and configures everything automatically. You get a URL like yourapp.vercel.app that you can share with anyone immediately.

If Vercel does not work for your specific app, ask your AI: "My app is built with [describe what you used] — what is the best way to host it so I can share it with others?" It will give you a specific recommendation.

If You Built a Script

A script — something that runs and does a task rather than showing a visual interface — cannot be shared via a URL. There is nothing to visit.

If the person you want to share it with is technical, put your script on GitHub as a public repository with a README explaining how to run it. They can clone it and follow your instructions.

If the person is not technical — which is usually the case — the honest answer is that sharing a script means turning it into something they can use without running code themselves. That might mean building a simple interface on top of it, or hosting it somewhere that runs it on their behalf.

Ask your AI: "I want to share this script with someone who is not technical. What is the simplest way to let them use it without needing to run any code?" It will suggest the most practical path for your specific situation.

If You Just Want Someone to Try It Right Now

The fastest option that requires zero setup: share your screen on a video call. They experience your app immediately, you get genuine feedback, and you have not had to set up hosting yet. Not scalable — but perfect for getting early reactions from one person today.

Use this to buy yourself time while you work through the Vercel setup.

The One Thing to Remember

You cannot share an app running on localhost — that address only works on your machine. To share it with someone else it needs a real internet address. For web apps, Vercel is the fastest and most beginner-friendly path. For scripts, the approach depends on whether the other person is technical. For right now, screen sharing gets you immediate feedback while you figure out the rest.
