Replit Launches Canvas: Infinite UI Design Tool with Live Previews
Replit has introduced Canvas, a spatial UI design tool featuring an infinite board where app frames are live browser instances rather than static screenshots. The tool supports interactive previews at mobile (390×844), tablet (768×1024), and desktop (1280×720) resolutions. Users can add freehand strokes, shape overlays, and sticky notes as first-class objects on top of live frames. Replit's Agent generates multiple design variants side by side; selecting one writes changes directly to the live codebase. Exports are available as editable PPTX, Google Slides, or PDF with component-level vector output. Canvas replaces Replit's older Design Mode and was released with the Agent 4 update, collapsing the gap between prototyping and shipping by keeping the running app and annotation layer in the same space.
