Devtools — Five new packages for inspecting json-render apps in the browser: @json-render/devtools (framework-agnostic core), plus @json-render/devtools-react, @json-render/devtools-vue, @json-render/devtools-svelte, and @json-render/devtools-solid adapters. Drop <JsonRenderDevtools /> into your app to get a shadow-DOM-isolated panel with six tabs (Spec, State, Actions, Stream, Catalog, Pick), a DOM picker that maps clicked elements back to spec keys via data-jr-key, a capped event store, and server-side stream tap utilities. Floating toggle or Cmd/Ctrl + Shift + J, tree-shakes to null in production (#273)
Devtools example — New examples/devtools Next.js demo showing the full devtools panel wired up to an AI chat endpoint and a component catalog (#273)
Action observer and devtools flag in core — @json-render/core now exposes an action observer and a devtools enablement flag that adapters use to mirror actions and stream events into the panel (#273)
Bug Fixes
Zod 4 schema formatting — formatZodType now correctly handles z.record(), z.default(), and z.literal() types from Zod 4, which previously produced incorrect or empty output in generated prompts and schemas (#239)
Improvements
Zod 4 test coverage — Added unit tests for formatZodType covering record, default, and literal types to guard against regressions (#272)
Gaussian Splatting — Added GaussianSplat component to @json-render/react-three-fiber, bringing the component count to 20. Composable with all existing R3F components (lights, controls, post-processing) via drei's Splat loader (#259)
Standalone gsplat example — Experimental demo app showcasing Gaussian Splatting with gsplat.js (no Three.js dependency), featuring scene selector, live JSON spec viewer, and progress indicator (#259)
R3F gsplat example — Demo app with five scenes: splat showroom, splat with primitives, multi-splat, post-processing effects, and animated floating splat (#259)
Improved
AI output quality — Improved prompt output and schema generation for more reliable AI-generated specs (#268)
