+Good React fit

FIG-005 / LIMITATIONS

where each falls short.

▣ svelte json view lite 3

−Focused on viewing, not editing
−No virtualization for very large JSON documents
−Smaller ecosystem than older React JSON viewers

▢ @uiw/react-json-view 2

−React-only
−Not API-compatible with react-json-view-lite migrations

FIG-006 / VERDICT

the honest call.

These are not drop-in alternatives within one framework. Choose @uiw/react-json-view for React apps; choose @humanspeak/svelte-json-view-lite for native Svelte 5 integration and snippet overrides.
