Flipflop is a new file sharing tool built on Iroh that creates persistent tunnels between devices for seamless, always-on transfers. Developed from frustrations with LocalSend and DashBeam, it aims to be fast, experimental with the Slint UI framework, and capable of connecting trusted external contacts reliably. The app works over Bluetooth, LAN, or the public internet, enabling users to send files, links, or plain text anytime once a tunnel is established.
It supports Linux, macOS, Windows, and Android, with platform-specific setup notes: Windows triggers Defender warnings, and iOS builds are unavailable due to Apple's restrictions. Build instructions include `cargo run --release` for desktop and `just android-install` for Android (requiring cargo-apk, Android SDK, and NDK). Releases are available on the project’s page, offering a decentralized alternative for personal and household device syncing.
