Start your app’s local development server, then copy the protocol, host, and port shown in its startup output or run configuration. A common format is http://localhost:PORT/, but the port depends on the server. A project folder alone does not create a working URL; a server must be running and listening on your computer.
Find the address your development server is using
- Start the app’s development server with the command or run configuration documented for your project.
- Look in the terminal or IDE output for an address such as
http://localhost:8000/. If no address appears, check the server’s run configuration or documentation for its host, port, and protocol. - Copy that complete address into a browser on the same computer. Keep the scheme (
httporhttps), hostname, and port as shown.
The port is specific to the server. For example, MDN’s Python local-server instructions use port 8000 by default and show opening localhost:8000 in a browser. Apache’s examples use http://localhost/ on its default port and http://localhost:8080/ when configured for an alternate port. Don’t assume your project uses 8000, 3000, 5000, or any other familiar number.
What localhost means—and when to use an IP address
localhost points to the computer making the request. The loopback address 127.0.0.1 generally refers to the same local machine; MDN describes it as generally known as localhost. Loopback access is limited to that device, unlike an address reachable over a local network.
That distinction matters when you test on another device: entering localhost on a phone points to the phone, not your development computer. Use a network-reachable address with the server configured to accept the connection, or set up a forwarding method. For Android testing, Android Developers documents ADB reverse forwarding and Chrome DevTools port forwarding as ways to connect a test device or emulator to the development machine.

Choose the right protocol and hostname
HTTP or HTTPS
For many local development tasks, an HTTP URL such as http://localhost:PORT/ is sufficient. Use HTTPS when the feature you are testing requires it—for example, mixed-content behavior, HTTP/2 or later, or an API that requires a secure connection. web.dev explains when local HTTPS is needed.
Custom .localhost names
A hostname such as myapp.localhost may resolve to loopback in modern evergreen browsers, but support is not universal. Microsoft’s ASP.NET Core and .NET 10 guidance reports that Safari on macOS does not support this behavior. Microsoft’s guidance is specific to that framework and version; if compatibility is uncertain, use plain localhost.

If the URL does not open
- Connection refused: Check that the development server is still running and that the URL’s port exactly matches the server’s listening port.
- No port is shown: Don’t guess. The server may use a protocol’s default port or display its address elsewhere; check its output, run configuration, or documentation. Apache’s examples show why the configured port matters: its default-port URL omits a port, while its alternate-port example includes
:8080. - A blank page or unexpected response: Confirm that you opened the right scheme, hostname, and port, then check the server’s error output or logs. Apache recommends checking its error log if its installation test page does not appear.
- Testing from another device: Remember that the other device’s
localhostmeans itself. Configure network access or use a forwarding method such as the Android options above.
