What is Claude Design and why does it cost a fortune?
In mid-April 2026, Anthropic released Claude Design, and the entire design world exploded with enthusiasm. The concept is simple but powerful. Describe what you want in a single sentence, and the tool delivers a fully interactive HTML design result instantly, without Figma, without Photoshop, and without you even needing to know how to design.
The enthusiasm didn’t last long. Reality hit hard. Claude Design is exclusively available for paying users, completely closed source, all data must be uploaded to Anthropic’s cloud, switching to other models is not possible, and self-hosting is out of the question.
Claude Pro costs from 200 dollars a month at the higher levels, a subscription price that is rarely seen in the consumer segment. It’s about what some people pay in rent for a storage unit. The difference is that the storage unit actually holds things you own.
Open Design took eleven days to build
Anthropic launched Claude Design on April 17. Eleven days later, the nexu io team published Open Design with the same artifact-focused design flow, under the Apache 2.0 license and with local execution as the default.
The nexu io open design project positions itself as a free local alternative to Claude Design, and its growth rate in popularity has impressed the industry.
It’s a bit like someone built a car, priced it at a million crowns, and a week and a half later, the neighbor parked an identical but free car outside your front door with a note saying just take it.
This is how Open Design works technically
Open Design is an open-source and local design workspace tool built on the same core idea as Claude Design. You describe what you want, and an AI system converts it into usable design output. Open Design runs on your own machine and uses your own coding agents and API keys instead of forcing you into a single hosted product. The project is free to use, with costs only for the AI provider you choose.
Open Design is not dependent on a single model or a single provider flow. The project converts existing coding agents such as Claude Code, Codex, Cursor, Gemini, OpenCode, and Qwen into the design engine.
The tool supports over 259 ready-made skills and 142 design systems, and can export to HTML, PDF, PPTX, and MP4.
Structured workflows instead of single prompts
One of the more intelligent solutions in Open Design is how it handles creative input.
Open Design relies not only on prompts but combines skills and design systems to guide the generation process. Skills define what is created, such as a landing page, a dashboard, a presentation, or a mobile app. Design systems define how the result should look by establishing rules regarding layout, typography, spacing, colors, and visual style.
It’s somewhat like giving a talented intern clear brand guidelines instead of just shouting do something nice and hoping for the best.
There is a wide range of built-in skills for common design tasks, including landing pages, dashboards, documentation sites, presentations, blog layouts, mobile apps, and web prototypes.
The freedom to choose a model is the real argument
The biggest difference between Open Design and Claude Design is ownership. Open Design is free and open source without subscription requirements for the software itself. You still need access to an AI model, and any API costs depend on the provider you choose, but the platform does not lock you into a recurring software fee.
A full 55 percent of organizations now report that avoiding vendor lock-in is a driving force behind open source adoption, an increase of 68 percent compared to previous years.
In other words, even companies can no longer afford to put themselves in dependency situations. If multinational corporations are pulling their ears back, perhaps individuals should consider this extra carefully.
Data security and transparency
Open Design follows a strict architecture where users bring their own API keys at every level. There is no telemetry embedded in the project itself, and the project maintainers do not receive data from user sessions. However, design prompts and generated content are directed to whichever AI provider the user has configured. A user running Claude Code as their design engine is subject to Anthropics’ data policies, while a user running Codex is subject to OpenAI’s.
The project is certainly transparent about that distinction, which is more honesty than most SaaS products offer.
Open Design reconstructs the workflow rather than trying to reinvent it. You generate designs, iterate on them, preview the results, and export finished artifacts much like in Claude Design. The difference is that you are not locked into a single vendor, subscription, or ecosystem.

| Source Code | Closed | Open under Apache 2.0 |
| Running | Cloud-based | Local and self-hosted |
| AI models | Anthropic only | Optional agent |
| Data storage | Anthropic’s servers | Your machine |
| Export | PDF, PPTX, HTML, Canva | HTML, PDF, PPTX, MP4 |
Why Open Design quickly won
Eleven days. That is what it took to transform a paid product into a free alternative. It says something about the current state of the AI industry.
The factors in favor of Open Design:
No cost for the software Freedom to switch AI model depending on task and budget All data remains local if the right agent is chosen Ability to fork, modify, and customize code No dependency on a single vendor’s product decisions
The only genuine downside is that you need to be comfortable setting up your own environment and that you still pay for AI API calls. Free is free, but tokens are not free.
Advantages

FAQ
What is Open Design? Open Design is an open-source tool that serves as a local alternative to Claude Design. It allows you to create design artifacts using your existing AI agent without subscription costs for the software.
How does Open Design differ from Claude Design? Claude Design is tied to the Anthropic ecosystem and requires a paid subscription. Open Design is free, runs locally, and supports any AI agent.
Does Open Design cost anything at all? The software itself is free. You still pay for API calls to the AI provider you choose, but you avoid a fixed monthly fee for the design tool.
Is Open Design difficult to install? It requires basic technical understanding to clone a repository and run pnpm commands. It’s not rocket science but also not a simple click.
How popular has Open Design become? The project gathered over 40,000 GitHub stars in a short time, which is a remarkable growth for a relatively new project.
