SilentShare — A Browser-Based Peer-to-Peer File Sharing App

#javascript #showdev #sideprojects #webdev

Have you ever been in a computer lab, classroom, or office where you needed to quickly send a file between your phone and laptop?

I run into this problem all the time.

Sometimes there's no USB cable, no pendrive, Bluetooth is painfully slow, or uploading to cloud storage just to download the file on another device feels unnecessary.

So I decided to build SilentShare.

What is SilentShare?

SilentShare is a browser-based peer-to-peer file sharing application that lets you instantly share:

📁 Files (up to 50 MB)
💻 Code snippets
📝 Text
🖼️ Images

No installation.
No account.
No server storing your files.

Your data goes directly from one device to another using WebRTC.

Whether you're sending files from your phone to your laptop, between classmates, or across the internet, SilentShare keeps the process simple.

Why I Built It

I wanted something that:

Opens instantly in any browser
Doesn't require creating an account
Doesn't upload files to someone else's server
Works on desktop and mobile
Feels lightweight and fast

Instead of relying on cloud storage, I wanted the browser itself to become the transfer tool.

How It Works

Other devices join
Start sharing instantly

The files are transferred directly between devices instead of passing through a storage server.

Privacy

One of the goals of SilentShare was privacy.

No user accounts
No cloud storage
No permanent database
Nothing stored after the browser tab closes If you set a room password, all transferred data is encrypted end-to-end using AES-GCM.
