The Verdict
Penpot is built for open source teams and privacy focused designers, with a focus on vector-editing and prototyping. Stable Diffusion targets developers and artists and leads with text-to-image and img2img.
On pricing, Stable Diffusion is the clear winner for budget-conscious users — starting at $0.01/mo compared to $8/mo for Penpot. That $7.99/mo difference adds up quickly for growing teams.
