Design System Diaries is a curated blog that explores the realities of building and running design systems inside modern product teams. Written by Lewis Healey, it focuses on behind-the-scenes challenges, decisions, and trade-offs faced by teams working on large-scale design systems, with a strong emphasis on practical experience rather than theory.
The content covers topics like design–code alignment, system governance, tooling, and emerging trends such as AI in design systems. It’s especially valuable for design system designers, design engineers, and design leaders who want grounded insights, thoughtful analysis, and lessons learned from real production systems—not just polished frameworks or surface-level patterns.
