FileSync is a self-hosted web application for sending files from one device to many in real time over encrypted peer-to-peer WebRTC connections. A lightweight FastAPI signaling server brokers connections but never sees file contents, and received files stream to disk with no size limit.

Use cases

• share files between devices without uploading to a cloud
• send large multi-gigabyte files with no size limit
• broadcast files to many devices at once via a room link or QR code
• self-host a private file transfer service
• transfer files across networks with NAT traversal
• share files without creating accounts or installing apps

When to choose

• you want private, peer-to-peer transfers where the server never sees file contents
• you need one-to-many file distribution in real time
• you want a self-hosted alternative with a single Docker image
• recipients should just open a browser link with no installs

When to avoid

• you need asynchronous transfers where recipients are offline when files are sent
• you want permanent cloud file storage or file history
• you cannot run a server or Docker container
• you need transfers through restrictive firewalls without TURN relay setup
