Hey Product Hunt 👋 I'm Dómini García, a software engineer by background. I built DevTools Hub mostly solo, leaning hard on AI-assisted development — and that's the honest story: once I saw how much ground one person could cover with AI pairing on implementation, I wanted to actually ship something real with it, not just experiment — and see whether a side project built this way could eventually become a real source of income, maybe even something I could work on full-time one day. The AI-assisted part is why there are 163 tools instead of 10. But the engineering judgment is still mine: every piece of tool logic gets a real test suite before it ships (one caught a genuine bug in the Markdown Table Generator's column-counting logic before it ever went live), and the whole site runs on one small registry pattern, so adding a tool/toolkit/post is a few files + one array entry, not copy-paste sprawl. What you actually get: 163 tools across 28 toolkits, 100% client-side (open devtools, check the network tab — nothing you paste ever leaves your browser), no sign-up, no ads, free. Still very early days for this. Would love your feedback — especially which tool you'd actually reach for, or what's missing.
