Small Studio

HTML/CSS editor · synthetic browser demo

Edit HTML and CSS, see an isolated preview, and save local revisions. Import and export JSON packages.

Use non-sensitive demo content. Browser saves share this website’s origin and can be read by other code on the site; this is not private cloud storage. No model generation or backend is connected. Browsers without Web Locks can preview/export but cannot save/import.

128 KiB per source. HTML/CSS only: scripts, links, forms and external resources are disabled in preview.

Live preview

Isolated preview · no scripts, network or access to this editor. Export keeps your original source.
