What is Flipflop?

Flipflop establishes a trusted connection between two or more devices so you can send files at any time. It supports transfers over Bluetooth, local area networks, and the public internet. The application relies on Iroh for peer-to-peer networking, allowing direct device communication without relying on central servers.

You can use the tool to share documents, images, links, and plain text across different operating systems. It is designed for everyday use within a household or for sending data to family members who are not nearby. The project provides precompiled builds for Linux, macOS, Windows, and Android.
