Compatibility

For the best chance of this working, we recommend using the latest version of Raspberry Pi OS, which is currently version Bookworm.
Raspberry Pi OS has 32-bit and 64-bit variants, both of which will run on most Raspberry Pi computers, including the Pi 3, Pi 4, and Pi5.
OnionShare will only run on PiOS 64-bit. Pi-Apps will not let you install OnionShare on PiOS 32-bit.
