A new project called Flipflop, shown on Hacker News, lets users set up a trusted tunnel between devices so files can be sent from one to another at any time.
Flipflop is built around a simple idea: once a trusted tunnel is established between two or more devices, either side can send files to the other whenever it wants. The tunnel stays in place, so the pairing does not have to be repeated for each transfer.
According to the project description, connections can run over Bluetooth, a local network or the wider internet. Under the hood, the tool relies on Iroh. The author suggests using it to move links, plain text and other content between all of your own devices, and possibly those of family members, whether they are in the same home or far apart.
Builds are available for Linux, macOS and Windows, along with an Android APK, all listed on the project's releases page. Windows users can run the executable directly or use the setup installer. The author notes that Windows will show a "Windows protected your PC" warning when the program is launched. An iOS version is not available, as the author says they cannot publish it for that platform.
Developers who want to build it themselves can use cargo run –release for the desktop version. The Android build uses the command just android-install and requires cargo-apk, the Android SDK and the NDK.
