Introducing the new OpenDesign Harness. More polished, complete designs with fewer prompts and tokens. Our experiment achieved SOTA quality at ~1/20 the cost. Over 88% of survey respondents rated it positively. On by default for everyone tomorrow. Demos up next ↘️

1) Let people explore your product. Turn a static presentation into an interactive demo that feels like your brand, where visitors can discover details at their own pace. Before → After: an iPhone 18 concept teardown, built to be explored.

2) Your brand, across every page. Designs follow your brief and design system, with imagery that fits your product and business—not just the layout. Before → After: a more cohesive landing page, with visuals that help tell the right story.

3) Go beyond the first screen. Build complete, clickable apps with real navigation, multi-step flows, and state changes that carry across pages. Before → After: follow the journey from start to finish.

1/20 cost looks strong but downstream edit time matters more than first pass ratings

harness doing the heavy lifting at 1/20th cost is the move curious if it still holds when the brief gets messy mid flow

The design-system constraint is the key. Generated UI gets much stronger when components, icons, and imagery inherit the same visual rules.

Does the harness override the agent we chose? For example, if I choose the Pi Agent in the chat...

The harness currently supports OpenCode, Open Design, Codex, and Claude Code. Pi isn’t supported yet, but we’ll keep you posted as we add support for more agents!
