Reviewer scorecard
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Non-negotiable for any serious component library. Visual testing, docs, and interaction testing in one place.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“Setup can be painful and builds are slow, but the alternative — no component isolation — is worse.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
“The best way to browse and understand a design system. Addons for accessibility and responsive testing are invaluable.”
