The Developer's Guide to Generative UI in 2026

AI agents have become much better at reasoning and planning. The UI layer has mostly stayed the same, and it is holding back the experience. Most ...

This three-pattern taxonomy is super helpful! I built a language called Almadar (subset of JSON with a Lisp) squarely around the declarative approach. A single .orb schema file is the source of truth that compiles into full-stack code (React, FastAPI, Axum, database models, types).
Our traits (you can think of them as hooks for now) use render-ui effects that return structured UI descriptions, not raw HTML:

["render-ui", "main", {
  "type": "entity-table",
  "entity": "Task",
  "columns": ["title", "status"],
  "itemActions": [{ "label": "Edit", "event": "EDIT" }]
}]

This is a side effect of an event in our schema (for example, user navigated to this page)

Each type maps to a validated component via a Pattern Registry — same idea as A2UI or Open-JSON-UI. Finite set of patterns, validated props, enforced event contracts.
What keeps it deterministic is our Closed Circuit Pattern: every user action emits an event → state machine checks guards → fires transition → executes effects → renders new UI → loop. The UI is never a dead end, and the LLM's creativity operates at the schema authoring level (Natural Language → OrbitalSchema), not at rendering time.
Your rule of thumb. More model freedom, more guardrails needed — matches our experience exactly. Constrain the generation surface to validated patterns and state machines, and you get declarative flexibility with static-level reliability.

This is one of the best articles I've seen this year. Super cutting edge topic, rounded up so well.

Great job @anmolbaranwal

Amazing resource for Generative UI, Anmol.
Kudos!

thanks Nathan! Also trying to recreate the playground repo from scratch, such a great learning experience :)

Solid write-up. complete end-to-end integration flow would have been interesting, though it might be a bit much for one post to cover all three patterns.
