Open Source Higgsfield: ComfyUI Build Night
Higgsfield said they’d open source their platform. Let’s help them.
Join the Comfy team and community in New York for a night of building as part of the Open Source Higgsfield Competition.
Bring your laptop, pick an app you love—Genjutsu, Cinema Studio, or something else—and rebuild it open-source on the Comfy Developer Platform, with in-person support from Comfy devs.
Come start your entry, finish it, or just see what everyone’s building. In-person attendees will be eligible to submit until the end of the event day.
