Summary
open_sourceflag fromtruetofalsein wallet dataDetails
MetaMask was originally licensed under MIT, but in August 2020 ConsenSys switched all MetaMask repositories to a custom proprietary license. The code is publicly viewable ("source-available") but does not meet the Open Source Definition maintained by the OSI.
Key restrictions in the current license:
metamask-extension: Non-commercial use only, with a hard cap of 10,000 monthly active users on any derivative workmetamask-mobile: Even more restrictive -- grants only a license to inspect and study the code; no modification or distribution without ConsenSys consentmetamask-sdk: Same restrictions as the extensionThese restrictions fail multiple OSI criteria (free redistribution, derived works, non-discrimination against fields of endeavor), making the "open source" designation inaccurate.
