The problem
Sending a large file between two devices usually means uploading it to someone's cloud, waiting, and trusting that copy to be deleted. Apps and accounts add friction, and office and mobile networks often block direct connections.
Our judgment
- 01
Peer to peer by default
Files travel directly between browsers over WebRTC, encrypted with DTLS. Our server only helps the two sides find each other.
- 02
A relay for difficult networks
When a network refuses direct connections, the encrypted stream passes through our relay instead, and is still never stored.
- 03
Built for phones
Large files are chunked with backpressure so memory stays flat, and transfers resume after a dropped connection.
In production
Screens from the running products, with example data.

How it is built
Nothing to install
Open a page and you are ready. Works on phones, tablets and computers.
No account
There is nothing to sign up for. A room code is all anyone needs.
Encrypted end to end
Every transfer is protected by DTLS, whether it goes direct or through a relay.
Any size, any number
Large files are chunked with backpressure, so memory stays flat on a phone.
Resumes after a drop
Lose the connection mid-transfer and it continues where it stopped.
Rooms of up to 24
Everyone in the room sees what is on offer and takes what they need.
