Up until a few months ago, my biggest complaint with AI tools was that the free tiers simply did not cut it anymore. I have since accepted that there is no escaping paying for these tools now and have begun to write them off as a work expense. My current complaint is the fact that even the higher-tier plans come with absurd limits. Anthropic, as you would expect, is at the top of my list. I am on Claude Max, and I am constantly hitting my session limits. Claude Design, which the company launched a few weeks back, was particularly greedy when it came to consuming my weekly usage. I would burn through my weekly limit for the product before I had anything I would actually be able to use. That is when I went looking for a way out, and I landed on an open-source Claude Design clone that has me convinced I will never need to open the real thing again.
A short note before the breakdown. The product is called Open Design (a free, local-first alternative to Claude Design published under the Apache-2.0 license by the nexu-io team). It does the same thing as Claude Design, runs against the same kind of coding agent you probably already have on your machine, and does not require a separate Anthropic subscription. If you are already paying for Claude Code, Codex, or Gemini CLI, Open Design rides on that existing setup. If you are not, you can paste in an API key and it will work against whatever model you point it at. Either way, you are not paying Anthropic for Claude Design on top of whatever you are already paying for the model underneath.
What Claude Design is, in case you missed the launch
The product is built around a single idea: you describe what you want, and the model returns a finished design artifact (a complete HTML/CSS layout, a slide, a component, a wireframe) instead of a wall of text about how you could design it yourself. You can edit the design right there, iterate on it through chat, and export the finished thing to PDF, PPTX, Canva, or hand it off to Claude Code once it is where you want it. The whole loop is conversation-first and artifact-first, in the same way that Cursor and Claude Code are conversation-first and code-first.
Claude Design went viral when it launched, and stayed closed-source, paid-only, cloud-only, and tied to Anthropic’s own models. That combination of lock-in is what pushed me off the product, even before I hit the weekly cap. I would build a wireframe I liked, and the only way to actually use it was to keep paying Anthropic.
What Open Design does differently
Open Design is built on the same loop (you describe, it builds, you iterate), but instead of running on Anthropic’s servers and Anthropic’s model, it hands the job to whatever coding agent you have already installed. That means Claude Code, Codex, Gemini CLI, OpenCode, or any other agent that exposes the same shape of API. It auto-detects whatever is already on your machine and wires it into the design workflow, which means there is not much configuration required from your end.
Two pieces of the design are worth calling out specifically:
- Bring Your Own Key (BYOK). You supply your own access to whatever AI model does the actual work, and you pay only for that usage on your own account rather than a separate subscription on top.
- Local-first. The tool runs against the agent on your machine. Designs are stored locally. There is no Anthropic cloud account involved, no Anthropic telemetry on your design sessions, and no “you must log in to save” gate.
- MCP-native. The product installs as a Model Context Protocol server (a standard for AI tools to expose capabilities to each other), so it integrates with Claude Code, Codex, Gemini CLI, and OpenCode through the same wiring.
- Apache-2.0 source. The nexu-io team publishes the source under a permissive license, so you can read it, fork it, and self-host it. There is no “we may change the pricing next quarter” risk.
- No rate limit on the design tool itself. The only rate limit is whatever your coding agent charges. If your Claude Code plan allows 200 sessions a week, Open Design can use all 200.
If you already have Claude Code or Codex authenticated on your machine, Open Design rides on that existing setup instead of asking you for anything new.
The developers explained that the whole point was to take the agent-native loop Anthropic shipped with Claude Design and strip out the parts that locked you in. The loop stays, the artifact-first approach stays, the lock-in goes. That is the entire pitch.
How it actually runs
There are four ways to get Open Design running, depending on how much setup you are in the mood for. You can grab the prebuilt desktop app, install it straight into your coding agent as an MCP server (Model Context Protocol, a standard way for AI tools to expose capabilities to each other), spin it up in Docker, or clone the repo and run it from the source. Instructions for each route are in the GitHub repository. I went with the run-from-source route and let Claude Code do the heavy lifting by asking it to set it up for me. It took about ten minutes, including the npm install and the first design render.
The first thing I built in Open Design was the same wireframe I had tried to build in Claude Design the week before: a one-page pricing table for a side project. The design took four iterations, and Open Design handled each one cleanly. The first render was not as polished as what Claude Design shipped out of the box, but it was good enough to iterate on, and the iterations were free (in the sense that I was using my existing Claude Code subscription, not burning a separate Claude Design weekly cap).
What I gave up
The first thing I missed was the polish of the first render. Claude Design’s out-of-the-box design quality is high. Open Design’s first render is functional but rougher, and you have to do more iteration to get to the same level of polish. If you are the kind of person who is happy with “rough but functional” as a starting point, this is not a real cost. If you need the first render to be 90 percent of the way there, you will feel the gap.
A polished first-time user experience is also gone. Claude Design is a polished web app with onboarding, templates, and a design gallery. Open Design is a developer tool with a CLI and a config file. The setup is not hard, but it is not the same as clicking a button in a vendor’s web app. If you are non-technical, Open Design is not for you. If you have ever installed a coding agent on your machine, you can install Open Design.
A couple of edge-case tools are also gone. The export-to-Canva integration that Claude Design ships is not yet in Open Design. The export-to-PPTX works but the slide layouts are not as polished. If those specific export paths are the reason you were using Claude Design in the first place, you should wait. If you mostly export to PDF and HTML (the two formats Open Design does well), you will not notice the difference.
Trade-offs
Open Design is not free in setup time. The run-from-source route took me about ten minutes on a fast machine with Claude Code already installed. If you are starting from zero, plan for an afternoon. The prebuilt desktop app is faster but less customizable. The Docker route is the most reproducible but the most setup.
Open Design is also not free in design polish. The first render is not as good as Claude Design’s. The iteration loop is fast enough that you can close the gap, but you will do more rounds of “make this less ugly” than you would in the vendor product. For my use case (wireframes and internal docs), this is fine. For a production design that ships to a real audience, you will probably end up in Figma anyway, and Open Design becomes the fast-rough-throw-away tool.
The local-first model has a real upside I did not appreciate until I had been using it for a week: there is no vendor telemetry on what I am designing, no “Anthropic has improved Claude Design for users like you” email follow-up, and no rate limit beyond whatever my coding agent charges. If you are uncomfortable with the fact that Claude Design knows every wireframe you have ever built, Open Design is the cleaner story.
If you are on a budget and cannot justify a Claude Max subscription for the design work alone, Open Design plus a $20/month Claude Code plan is the obvious move. If you are already on Claude Max and you are using Claude Design weekly, you can probably save the $20-40/month Claude Design charges by switching to Open Design and just using your existing Claude Code quota. If you are non-technical and do not want to install a coding agent, Claude Design is still the path of least resistance, and that is fine.
Bottom line
If you only do one thing from this article, install the Open Design prebuilt desktop app and run it against whatever coding agent you already have. The setup is ten minutes, the loop is the same as Claude Design’s, and you will know within an hour whether it is a real replacement for your workflow. If you finish that first session and the design quality is good enough for what you needed Claude Design for, you can cancel the Claude Design add-on next billing cycle and not look back.
Anyone who has been on the fence about Claude Design because of the price, the privacy footprint, or the vendor lock-in should try Open Design first. The fact that you can run it against a coding agent you already have on your machine makes the barrier to trying it almost zero. The fact that the source is open and the design is stored locally makes the cost of staying on it almost zero too. That combination is the entire reason the open-source clone exists, and it is the reason I am still using it two months later.
