Reviewer scorecard
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Code-first CMS that runs inside Next.js. Full TypeScript types, access control, and the admin UI is excellent.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“The best headless CMS for developers. Code-first configuration means version control and type safety.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
“CMS inside your Next.js app eliminates the API layer. Payload 3.0 is a paradigm shift for content management.”
