“I barely wrote any code for ColorCraft.ai. Seriously. This entire app was "vibe-coded" with AI, using tools like Cursor, and built on Supabase, Vercel, and Stripe.”
Editor's note: John Kirby builds ColorCraft on the side; he also runs short-term rentals. In a June 2025 post on X he said the whole app was vibe coded with tools like Cursor. In April 2026 he re-platformed and redesigned it with a design system from Claude Design, cutting deploys from 30+ minutes to under 2.
How they got customers
He launched on Product Hunt in April 2026 and posts about ColorCraft on X, but on Sep 20, 2026 he said he hadn't marketed it in months while MRR kept rising; TrustMRR shows about 2,300 Google Search impressions in the last 30 days. The biggest change he describes is pricing: his data showed users either generated 10+ pages and paid or never paid, so he dropped the free tier for a card-gated 7-day trial that lets people finish a whole book.
