Latest Updates
Hey everyone!
If you've used Crafts, you've probably hit this. You ask Merlin to build a React dashboard, a styled HTML page, or a diagram with more than a few nodes, and somewhere around the 150-line mark, the output just stops. Mid-function. Sometimes mid-tag. The AI cheerfully continues the conversation like the code is complete. It isn't.
That single bug report collected ~90 votes and had ~39 separate complaints merged into it. It was the loudest thing in our bug tracker for months, and we owe you an honest answer: the original Crafts was fundamentally broken for anything complex. We built it as a single generation call, the AI tried to output your entire file in one shot, hit its limit, and silently stopped. No retry, no warning, no signal that your code was incomplete. Just a broken component and a confused user.
So we rebuilt it from scratch.
What's new in Crafts v2
The core change: instead of one all-or-nothing generation step, the AI now builds files the way a developer would, in stages, with the ability to read what it wrote, fill in sections iteratively, and only show you the result when it's actually ready. No more silent truncation. No more half-finished code.
The result: files over 500 lines work properly. Files over 1,000 lines work. We've tested up to 7,000. The code that used to get cut off mid-function doesn't anymore.
A few other things that came with the rebuild:
- Iteration actually works. If a generated file has a bug, the AI can now read the specific section, replace just that part, and verify the fix, without regenerating the entire file from scratch.
- Model-aware generation. Claude, GPT, Gemini, DeepSeek, Kimi, and others each get instructions tuned to how they actually behave. One-size-fits-all prompting was silently failing on a lot of models. That's fixed.

Try it
The easiest test: ask Merlin to build something that would have broken before. A React component with charts and a sidebar. A styled landing page with multiple sections. A Mermaid sequence diagram with 20+ steps. That's exactly the kind of output v1 couldn't finish. It should work now.
