How I Built a SaaS Boilerplate for Vibe Coders in 2026

Vibe coding changed how I build software. I describe what I want, AI writes the code. But there's a problem nobody talks about. The 60-80 problem AI tools generate 60-80% of boilerplate correctly. The remaining 20-40% requires debugging, refactoring, and domain knowledge. This is where most vibe coders get stuck. The AI builds something that looks right, but under the hood it's fragile and inconsistent. My solution: give AI better context I built KitRocket — a SaaS boilerplate designed specifically for AI coding tools. The key insight: AI works better when it understands the codebase. Here's what that means in practice: Small files Every file is under 100 lines. AI tools have context windows — smaller files mean better comprehension. Consistent patterns Every module follows the same structure: lib/ → api/ → components/ → hooks/ → types/ . Once AI learns one module, it can build another. Types as documentation All shared types live in src/types/ . AI reads these to understand the data c
