python -m http.server: share a folder over the network with one command

Moving a few files from your computer to another device on the same Wi-Fi can be surprisingly annoying — emailing them to yourself, hunting for a flash drive, signing into the cloud. Yet if you have Python installed, one command is enough: python3 -m http.server turns the current folder into a miniature web server. Anyone on the same network can then open the folder in a browser like an ordinary page with a file listing — and download whatever they need. No install, no account, no cable.

How to do it

1. In a terminal, navigate to the folder you want to share and run python3 -m http.server (on Windows, py -m http.server). It prints a message that the server is running on port 8000.
2. Find your computer's IP address on the local network — on Mac and Linux, ip addr or your network settings show it; on Windows, ipconfig (the IPv4 address line) — typically something like 192.168.1.23.
3. On the other device — a phone, a tablet, someone else's laptop — open http://192.168.1.23:8000 in a browser. You'll see a folder listing; click a file to download it.
4. When you're done, stop the server in the terminal with Ctrl + C. Don't leave it running — anyone on that network can see the folder.
5. Two rules: share only a dedicated folder with exactly what you want to share (the server exposes everything, subfolders included), and use it only on a trusted network — home or office, not public Wi-Fi. The transfer isn't encrypted or password-protected.

A typical scenario

A developer needs to get a batch of test APK files onto their phone and photos from a presentation onto a colleague's tablet — three devices, two operating systems, no shared cloud. Instead of juggling cables, they start a server in the share folder, read the address out to their colleague, and both grab what they need at local-network speed. Two minutes later, the server's off. The same trick helps with web development: open a work-in-progress static page this way on your phone and see how it actually looks on mobile — the server automatically serves an index.html file in the folder as a page. Pick a different port by adding a number to the end of the command: python3 -m http.server 9000.

For regular transfers between your own devices, system tools like Nearby Sharing are more convenient — http.server wins when there are more devices involved, platforms are mixed, or the other party has nothing installed.

What you get out of it

A universal emergency bridge between devices that works anywhere Python and a shared network exist — no accounts, apps, or cables. Anyone who regularly runs into “get this over there” between mismatched devices will appreciate it, and web developers get an instant test server for static pages as a bonus.
