  4. 4Keep the source together with screenshots so teammates can reproduce the result.

FAQ

Does this send my source to a backend or AI service?

No. These P1 preview tools run locally in the browser for the supported parser path.

Is the preview a full production runtime?

No. It is a focused preview and debugging surface for common cases. Keep your browser, runtime, or production parser as the final authority.

JSON Diff Viewer is part of the DiagramPreview script and visual source preview toolbox.

It helps you close the gap between text generated by AI or copied from a project and the visual output that teammates actually review.

Use it as a quick validation step before turning snippets into docs, tickets, blog posts, or production examples.
