Comps

Penpot · penpot.app · Same buyer and job to be done: designers and developers collaborating on UI design. Both are open-format design tools competing for the same design workflow budget.[4][5]

Figma · figma.com · Same buyer and job to be done: product teams designing UI. pen.dev explicitly supports copying designs from Figma, and the CEO positions pen.dev as an alternative to the design handoff workflow Figma anchors.[1][2]

Framer · framer.com · Same buyer and job to be done: turning visual design into production code. Tom Krcha lists Framer among his skills and the design-to-code workflow overlaps directly.[2]
