Reviewer scorecard
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“Non-negotiable for any serious component library. Visual testing, docs, and interaction testing in one place.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Setup can be painful and builds are slow, but the alternative — no component isolation — is worse.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
“The best way to browse and understand a design system. Addons for accessibility and responsive testing are invaluable.”
