Open Design

Editor Review

You can start without an account. Install a coding agent, or enter your own endpoint and key, pick a design system, describe the screens, and the agent writes a previewable HTML prototype into the project. Afterward you can still move elements and change text, color, and spacing without regenerating the page. A design system can come from the open-source library or be created from a website, a code repository, or a design file. Team comments sit on the prototype and return to the agent as one revision, then you export HTML or PDF. It fits people and small groups who already have a coding agent and want the prototype and the design rules in one place. Hosted models and share links are on paid plans.

What is Open Design

OpenDesign is a design workspace that can run locally, or you can sign in to OpenDesign Cloud for hosted models. It calls a coding agent already installed on your computer, or your own API key, and writes a previewable HTML prototype into the project from a chosen design system. You can still edit elements after generation. Teammates comment on a share link, those comments go back to the agent as a revision, and you can export HTML or PDF. The free tier includes the full desktop app with a local agent or your own key. Hosted model credits and share links are on paid plans.

Open Design Key Features

Use a coding agent you have

Run it through a coding agent on your computer, or call a model with your own API key. Neither the local path nor bring-your-own-key requires an OpenDesign account first.

Prototype from a design system

Pick an open-source design system, or build your own from a website, repository, or design file. Color, type, spacing, and components then shape prototypes, pages, and decks.

Edit after generation

After generation, move and resize elements and change text, color, spacing, and alignment without regenerating the whole page.

Comments back to the agent

Share the prototype to a team workspace so teammates comment on the screens. Those comments return to the agent as one revision. Then export HTML or PDF, or hand the project to engineering.

Open Design Key Advantages

A local agent or your own key can run the desktop app without an OpenDesign account

A design system can be created from a website, repository, or design file and then applied to later prototypes

After generation you can change position, text, and spacing, and comments return to the agent as one revision

You can export HTML or PDF, or hand the project to engineering

Open Design Use Cases

Solo prototype with a local agent

A designer connects a coding agent already installed on the computer, picks a design system, describes the screens, previews the HTML, and tweaks it by hand.

A team commenting on a prototype

An owner publishes the prototype to a shared space, teammates comment on the screens, and those comments go back to the agent as a single revision.

Handing the system to engineering

After the prototype is set, export HTML or PDF, or hand the project and its design system to engineering.

Frequently Asked Questions

▶What works without an account?

The free tier includes the full desktop app. A coding agent already on the computer, or your own API key, needs no OpenDesign account. Hosted models, publishing, and share links are on paid plans. The team plan adds a shared space for projects, design systems, and plugins, with owner, admin, and member roles.

▶Can I edit a prototype after it is generated?

Yes. After generation you can move and resize elements and change text, color, spacing, and alignment without regenerating the page. Those edits stay in the current project and are included when you export HTML or PDF. To apply teammate feedback, share the prototype, collect comments, and send those comments back to the agent as one revision.

▶Where does the design system come from?

You can pick an open-source design system from the site, or build your own from a website, a code repository, or a design file. Color, type, spacing, and components then apply to later prototypes, pages, and decks instead of being set on every page. You can also keep a system just for your own team.
