Changelog / v1.17.0 / 16 Oct 2026

The live preview takes over sooner while a design builds

Agents now write and save the main page early, so the live preview shows a design taking shape mid-build, the build card leads with the design so far, and pages that never answer the preview are shown anyway.

  • "Design so far" leads the build card.

    While a new design builds, the sample composed from the saved stylesheets now sits at the top of the card, drawn larger, with the files written this run below it. The card says the live preview takes over the moment the main page is saved. The excerpt of the latest file's source is gone: the card shows the design, not code.

  • The live preview starts earlier in a build.

    Agents are now told to write the main page first and save it after each section or screen, instead of assembling it at the end, so the preview can show the design taking shape while the agent works. Design types built from a model, such as Mobile app, Social Media, Pixel Sprite, Diagram and Map, render the starter first and update as the model grows.

Fixed

  • Pages that never connect to the preview are shown anyway.

    A saved page that loads but doesn't answer the preview bridge, for example because one of its scripts failed early, used to keep the waiting card up for the rest of the run. After two seconds the preview now shows the page as it is, notes that picking and comments wait until it answers, and still refreshes on later saves.
