HTML Frames
New previewTwo frames, one canvas
See how your HTML actually looks.
Drop an HTML file onto the canvas and it opens in desktop and mobile frames side by side. Save it and it becomes its own page with a direct link — nothing to install, no account needed.

01
Drop the file
Drag an HTML file onto the canvas or browse for one. It renders immediately in both frames.
02
Check both sizes
Desktop at 600 px and mobile at 375 px, side by side, with scripts blocked so nothing runs wild.
03
Save as a page
Each save creates a new entry with its own link, so every version keeps its own address.
