Shipping Software Is Harder Than Building It

When I published v2.0.0 , I thought the hard part was over. The CLI could turn Claude artifacts into native Windows applications in a single command. It worked on my machine, the demos looked great, and I was excited to share it. Then people started using it. That's when I realized the difference between building software and shipping software . The bugs only users can find Most of the problems weren't visible in a five-minute demo. Some applications worked perfectly. Others silently lost all of their data after being closed. Some builds succeeded exactly once. The second build failed unless the runtime cache was manually deleted. Everything looked correct... until someone actually tried using it. The rabbit hole What I thought would be a quick patch became a deep dive into things I'd never touched before. Over the course of v3 I ended up learning far more than I expected: Git branching and release workflows Semantic versioning GitHub Actions npm packaging npm pack Runtime integrity verification SHA-256 checksums Neutralino runtime management JavaScript debugging Integration testing None of those were part of the original project idea. Persistent storage finally works This was the biggest challenge. Artifacts using localStorage behaved differently depending on where they were running. Inside Claude everything worked. Inside the generated desktop application... not always. Tracking this down took far longer than writing the original feature. The result is that applications now persist their data correctly across launches without requiring any code changes. If your artifact uses localStorage , it should simply work. Runtime improvements The runtime layer also received a major overhaul. Version 3 now handles: automatic runtime downloads integrity verification cache recovery consecutive builds without manual cleanup Those aren't exciting features to demo, but they're exactly the kinds of improvements that make a tool feel dependable. Better testing I also spent a lot mo
