Flipper Zero firmware differences

:: Last updated May 2nd 2022. ::

This document will (hopefully) maintain a list of differences between various forks of the Flipper Zero firmware.
If I had a dollar for every time I've seen this question asked, I wouldn't be in college debt. ¯\_(ツ)_/¯
Also consider checking out my Awesome Flipper Zero repo, and my rant about the two types of users.

Official flipperdevices/flipperzero-firmware

• Has region-locked Sub-GHz transmission because of legal limitations.
• Has no ability to save and send rolling codes (dynamic encrypted) in Sub-GHz, only shows them in captured list.
• Factory-set device name that shows everywhere (Bluetooth broadcast, USB connection, etc) can not be changed.
  • The Flipper team has a list of device names with their corresponding production information (No shipping address) so they can assist you easier in case of an RMA.

Wetox wetox-team/flipperzero-firmware

MuddledBox MuddledBox/flipperzero-firmware

• Updates are infrequent, lags far behind upstream firmware.
• Removes Sub-GHz transmission restrictions.
• Adds self-promo images to about page in settings.
• Adds a few extra common Sub-GHz frequencies to capture on.

Unleashed Eng1n33r/flipperzero-firmware

• (AKA Code Grabber firmware.)
• Very active development and Discord community.
• Removes Sub-GHz transmission restrictions.
• Adds extra Sub-GHz frequencies like Muddled.
• Can be used to capture and send dynamic encrypted protocols/rolling codes. (Modern grage doors, car fobs, etc.)
• Encrypted Sub-GHz signals/codes can be manually added.
• Comes with its own infrared databases.

Summary (TL; DR)

• Staying up to date with upstream (official) firmware is important.
• Wetox is good for making changes to your own firmware fork.
• MuddledBox was the first popular firmware fork, but never grew up.
• Unleashed is like MuddledBox plus more.
• Super TL; DR: Unleashed > MuddledBox.
