# Quick start

###### Get a local HTTPS domain and a shareable Public URL (tunnel) for an app running on your machine in a few minutes.

The steps below use the desktop app on macOS and Windows. On Linux, or if you prefer the terminal, follow the [CLI quick start](/docs/cli/quick-start).

1. **Start a local app.** Any app listening on a port works. For this example, create a Next.js app with `npx create-next-app@latest` and start it with `npm run dev`. It serves on `http://localhost:3000`.

2. **Add a project and an app.** Click **Add project** in the sidebar and give it a name. Then click **Add App**, name it `my-app`, and set the target to `http://localhost:3000`. LocalCan creates a local domain like `https://my-app.local` automatically.

3. **Trust the root certificate.** Open **Settings** and click **Trust Certificate** next to **Root Certificate** in the **Local Domains** section, then follow the prompts. This makes browsers accept HTTPS on your `.local` domains. Now open `https://my-app.local` and your app loads over HTTPS.

4. **Share it with a Public URL.** On the app's card, click **Add Public URL** and choose **New Public URL**. You get an address like `https://my-app.localcan.dev` that anyone can open.
