Higgsfield sends ComfyUI cease-and-desist over 'Open Source Higgsfield' challenge
TomLikesRobots · x · 2026-10-30
AI video company Higgsfield sent ComfyUI a cease-and-desist demanding the 'Open Source Higgsfield' challenge be taken down within 48 hours.
- The letter argues ComfyUI's use of the HIGGSFIELD trademark and CEO Alex Mashraborov's likeness implies false affiliation, citing the Lanham Act
- Demands include dropping the mark, removing the campaign video, and preserving all documents for potential litigation
- ComfyUI counters that Higgsfield promised to open-source its product and never did; the community has spent two weeks rebuilding its closed apps as open workflows, and the challenge is explicitly unaffiliated with Higgsfield
