How founders use AI for Vibe Coding

15 questions founders actually ask, each with a straight answer and curated resources to go deeper.

Why can non-technical founders now build software with AI? Coding models crossed a quality threshold in late 2024, and a wave of tools (Lovable, Replit, Bolt, Cursor) now turn plain-English descriptions into working ... 18 resources → What tools should I start with (Cursor, Claude Code, Lovable, Replit, Bolt, v0)? Match the tool to your comfort level: Lovable, Replit, and Bolt build full apps from plain English in the browser, v0 generates polished UI, while Cursor and... 19 resources → How do real founders ship an MVP with AI in days instead of months? The pattern is consistent: scope one core workflow, prompt a working prototype in hours, put it in front of 5-10 real users within days, and iterate on live ... 18 resources → What are the limits, when do I still need a real engineer? Vibe coding gets you roughly 70% of the way: prototypes, internal tools, and early MVPs. The last 30% (security, scale, complex integrations, gnarly bugs) is... 20 resources → What actually counts as vibe coding, and how is it different from serious AI-assisted engineering? Karpathy's original meaning was specific: let the AI write everything and do not even read the code. Simon Willison drew the now-standard line: if you review... 18 resources → How do I plan and prompt so the AI builds what I actually want? The single biggest upgrade is to stop prompting features and start with a spec: brainstorm the idea into a written plan (a mini PRD), break it into small ste... 18 resources → How do I keep my vibe-coded app from getting hacked? AI tools routinely ship apps with API keys in the frontend and database security (like Supabase Row Level Security) switched off; scans found roughly 1 in 10... 19 resources → How do I get my vibe-coded prototype ready for real users? A demo that works for you and a product that survives strangers are different animals: before launch you need real authentication, database rules, environmen... 18 resources → How do I add accounts, a database, and payments to my vibe-coded app? Almost every vibe-coding stack converges on the same trio: Supabase for the database, login, and file storage, Stripe for payments, and your builder (Lovable... 18 resources → What do I do when the AI gets stuck, loops, or breaks things it already built? The 'fix this, break that' loop is the number one vibe-coding frustration, and it is usually a context problem: the session's memory is full and the AI is pa... 18 resources → How much does vibe coding really cost, and how do I stop burning credits? Plan on $20-100 a month while building seriously: Lovable and Bolt charge in credits per message (a real SaaS feature burns 30-60 credits), while Claude Code... 18 resources → Do I still need to learn to code, or is prompting enough? You no longer need syntax, but you very much need computational thinking: how to break problems down, what a database or API is, and how to read what the AI ... 17 resources → Can vibe-coded products become real businesses? Yes, and the evidence is no longer anecdotal: Base44 sold to Wix for $80M six months after a solo founder started it, Pieter Levels' vibe-coded flight sim hi... 19 resources → Can I vibe code a mobile app and get it into the App Store? Yes: Replit's agent now builds React Native apps with Expo and walks you through TestFlight and App Store submission, while dedicated mobile builders like Vi... 18 resources → How do I avoid losing work? Version control for founders who don't code The most common regret among new builders is losing a working version they cannot get back. The insurance policy is Git: think of it as unlimited save points... 19 resources →
