Codex Design vs Uizard.
Uizard and Codex Design both generate app and website mockups from a description. Uizard is a drag-and-drop design tool for people who don’t code. Codex Design is a canvas for Codex, where every design is a live HTML page that the same agent can go on to build.

The short answer
If you don’t code and want to mock up an app idea in a friendly editor, Uizard is the easier tool. If you build with Codex and want designs that are real HTML from the start, Codex Design is the better fit, because the path from mockup to working code stays inside one agent.
- Choose Uizard if you want to drag and drop every element yourself, turn screenshots or hand-drawn sketches into editable mockups, or share prototypes with stakeholders who just view and comment.
- Choose Codex Design if you already use Codex, want each screen as a complete HTML page rather than an image, and plan to build what you design.
What each tool is
Uizard is an AI-powered UI design tool, part of Miro since 2024. Its Autodesigner generates multi-screen, editable prototypes from a text prompt, and you then adjust them in a drag-and-drop editor or by describing changes. Screenshot Scanner turns screenshots of apps into editable mockups, and Wireframe Scanner digitizes hand-drawn wireframes. Projects export as images or PDF, and paid plans add a handoff mode with CSS and React code for one component at a time.
Codex Design is our independent plugin for Codex. It adds a local canvas where Codex places the screens it designs as live HTML pages, next to mockup images and your references. Select an element to change its font, color, or spacing in a sidebar, or keep refining by asking Codex. Your canvas projects are stored on your computer.
Side by side
| Uizard | Codex Design | |
|---|---|---|
| What it makes | Editable multi-screen mockups and clickable prototypes | Website and app mockups as live HTML pages, plus mockup images |
| Where it runs | In Uizard’s own drag-and-drop editor | Inside Codex, with the canvas on your computer (macOS and Linux) |
| Output and code | JPG, PNG, SVG, and PDF; on paid plans, CSS and React code one component at a time; no whole-project HTML export | HTML pages and images in a local project; Codex can then build the chosen design in your code |
| Pricing | Free with 3 AI generations a month and 2 projects; Pro $12 a month billed yearly, with 500 generations | Free for one canvas project; Pro is $5 a month for unlimited projects. Codex usage is separate |
| Best for | Non-designers and non-coders mocking up an idea quickly | Codex users who want to compare and refine UI directions before they build |
Uizard’s Business plan is $39 a month billed yearly, with 5,000 AI generations a month. This comparison reflects both products’ official sites and docs as of November 6, 2026.
When to choose Uizard
Uizard is the better pick in these cases:
- You don’t code and don’t use a coding agent. Uizard’s editor is built around dragging and dropping, and Codex Design needs Codex, the Codex CLI, and Node.js on your computer.
- You start from something that already exists. Screenshot Scanner turns a screenshot of an app into an editable mockup, and Wireframe Scanner does the same for sketches on paper.
- You want to edit by hand. Every generated screen opens in a drag-and-drop editor, and you can also select a component and describe the change you want.
- You share with a crowd. Every plan includes unlimited free viewers and commenters.
- You want templates. Paid plans unlock Uizard’s full template library.
When to choose Codex Design
- You want real code, not snapshots. Every screen is a complete HTML page, with an element inspector and page version history. Uizard’s code export covers one component at a time and doesn’t export whole projects as HTML.
- You already build with Codex. The canvas sits inside the agent that writes your code, so there is no handoff between design and build. Ask Codex to implement the direction you picked.
- You compare directions side by side. Put several HTML directions next to each other, with mockup images Codex generates and your own references.
- You don’t want a generation cap from the design tool. Codex Design doesn’t count generations; what Codex makes counts against your Codex plan, as usual. One canvas project is free, and Pro is $5 a month for unlimited projects.
- You want your work on your own machine. Canvas projects are stored locally. Codex still processes whatever context you share with it.
Frequently asked questions
Is Codex Design a Uizard alternative?
Yes, if you use Codex or are comfortable with a coding agent. Both generate UI mockups from a description. Uizard keeps you in a visual editor with no code required; Codex Design keeps every design as live HTML inside Codex. If you don’t code, Uizard is the easier tool.
Can Uizard export code?
Partly. On Pro, Business, and Enterprise plans, Uizard’s handoff mode shows CSS and React code for one component at a time, which you can copy or download. Uizard says it can’t export a whole project as HTML or JavaScript.
