Inspiration
Heal Demo's UX owes a debt to a handful of products we studied closely while building: Arcade for the viewer step-through pattern, Linear for sparse product-focused marketing copy, and Vercel for clean documentation typography. None of these companies have endorsed Heal Demo; we just admire their craft.
