Running FilePizza with Docker on Synology NAS - Very Simple P2P File Sharing

When I first used Apple’s AirDrop, I was hooked. It was so seamless that I ended up buying not only an iPhone, but also an iPad and a MacBook just to enjoy that effortless file sharing.

Later, when I switched to Android for work, the biggest feature I missed was AirDrop. Android and Samsung offer similar tools, but they never felt natural. That’s when I started searching for alternatives: Snapdrop, PairDrop, Sharedrop, LocalSend, even Syncthing. Unfortunately, on my Synology NAS they caused trouble — CPU minimum requirement, redirect loops, or system tweaks I didn’t want to make.

Then I discovered FilePizza. It’s small, simple, and does exactly what I needed. The concept is brilliant: files are delivered peer-to-peer through your browser, without being stored on the server. Just like ordering a pizza, the file goes straight to its destination.

Why FilePizza?

• Peer-to-Peer sharing using WebRTC
• No server storage – your NAS only coordinates connections
• Browser-based – no client apps required
• Lightweight & simple – perfect for occasional transfers

Deploying FilePizza on Synology NAS

FilePizza runs perfectly inside a lightweight Docker container. With Synology Container Manager → Project, you can set up a new project and paste in the following service definition:

services:
  filepizza:
    image: kern/filepizza:latest
    container_name: filepizza
    environment:
      - NODE_ENV=production
    ports:
      - "3002:3000"
    restart: unless-stopped

This ensures FilePizza is always available inside your NAS, mapped to port 3002.

Reverse Proxy Setup

To make access seamless and secure, set up a Reverse Proxy in Synology DSM:

• Source: https://filepizza.domain.com
• Destination: localhost:3002
• Attach an SSL certificate to ensure HTTPS (required by most browsers for WebRTC).

With this configuration, your FilePizza instance is reachable at:
👉 https://filepizza.domain.com

How to Use FilePizza

Using FilePizza is as easy as it gets:

1. Open https://filepizza.domain.com in your browser.
2. Drag & drop the file you want to send.
3. Share the generated link with the recipient.
4. As soon as they open the link, the file transfers directly from your browser to theirs.

There’s no extra app, no account, no storage — just instant peer-to-peer delivery.

Final Thoughts

If you’ve been missing the simplicity of AirDrop, FilePizza on Synology NAS is a fantastic lightweight replacement. With Docker and Synology’s Reverse Proxy, you get a private, browser-based sharing service at filepizza.domain.com — always available, always under your control.
