Flipper Zero firmware differences

:: Last updated July 10 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 the Awesome Flipper Zero list, and my rant about the two types of Flipper 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.

Unleashed Eng1n33r/flipperzero-firmware

• (AKA Code Grabber firmware.)
• Very active development and Discord community.
• Removes Sub-GHz regional transmission restrictions.
• Adds extra Sub-GHz frequencies.
• Adds extra mifare classic keys.
• 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.
• Current modified and new Sub-GHz protocols list.
• Comes with extra custom apps from community. Apps List.
• Other small tweaks and changes.

RogueMaster RogueMaster/flipperzero-firmware-wPlugins

• Firmware with regional TX restriction removed.
• Has Sub-GHz protocol changes copied from Unleashed FW.
• Adds extra Sub-GHz frequencies.
• Adds extra mifare classic keys.
• Experimental Games only/DUMB mode.
• Has some other small changes.
• Most known community plugins & games have been added.
• Full list in their README.

Wetox wetox-team/flipperzero-firmware

• The dev branch is intended for public use, while others are either testing or archived hackathon submissions.
• Cracking T5577 RFID passwords via dictionary attack.
• Desktop header branding [WTX].
• Has some frequently updated interesting experimental stuff in different branches.

MuddledBox MuddledBox/flipperzero-firmware

• Abandoned. Not updated for more than 2 months.
• Removes Sub-GHz regional transmission restrictions.
• Adds self-promo images to about page in settings.
• Adds a few extra common Sub-GHz frequencies to capture on.

Summary (TL; DR)

• Staying up to date with upstream (official) firmware is important.
• TX restriction removal is illegal in most circumstances, use at your own risk.
• MuddledBox was the first popular firmware fork, but didn't grow up.
• Unleashed is more focused on the core functionality and Sub-GHz protocols, only stable community apps are included.
• RogueMaster has more community plugins and other small changes.
