Reviewer scorecard
“Mature API, excellent SDKs, and the content model is flexible. The enterprise choice for headless CMS.”
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“Expensive for what it is. Sanity and Payload offer better DX at lower cost. Only justified for enterprise compliance needs.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“The editor experience is functional but uninspiring. Sanity's customizable studio is more pleasant to work in.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
