VibeStack — design systems for AI coders

About

VibeStack is a profitable-ready design system SaaS for "vibe coders" — the fast-growing group of Vibecoders/developers shipping apps with Lovable, Cursor, v0, Bolt, Claude Code, Replit Agent and Windsurf. Their problem is universal: AI-generated apps all look generic, like the default shadcn slate-and-zinc template. VibeStack fixes that in one prompt to paste.WHAT IT DOESUsers browse a curated library of 27 full themes, 45 color palettes, 18 professional font pairings, 200,000+ icons across 150+ icon families, and a UI Elements library (buttons, inputs, navs, toggles, and notifications). They mix and shuffle combinations, then copy a single engineered install prompt, or export a full Tailwind starter project as a ZIP. The AI tool applies colors, typography, radii, shadows, motion, and component styles in one generation.WHAT'S INCLUDED- Full source code: React 18, Vite, TypeScript strict, Tailwind, shadcn/ui, Framer Motion- Complete backend: Postgres with row-level security, auth (email + Google OAuth), 21 serverless functions- Live payments integration (Paddle as Merchant of Record - handles global tax, invoicing and refunds for you), with Pro Monthly ($9.99/mo) and Pro Lifetime ($200 one-time) tiers, self-serve cancellation, and lifetime-upgrade flow- AI features: AI-assisted theme shuffle with per-plan quota metering- Full transactional email system: welcome, trial lifecycle (day 5/6/8), order confirmation, cancellation, unsubscribe handling, and suppression list- Admin panel: feedback inbox, user invites, email testing- Marketing site: landing page, pricing, FAQ, 5 how-to guides, legal pages, sitemap, llms.txt, and ai.txt for AI-search visibility, JSON-LD structured data- A rendered 60-second product walkthrough video (Remotion project included, fully re-renderable)- Custom domain vibestacks.pro included in the saleTRACTIONLaunched recently and intentionally kept small while the product was polished: 13 registered accounts, 4 paid subscription records, and 2 lifetime purchases to date. Revenue is early, so this is priced as an asset sale, not a multiple. The value is a finished, production-deployed, monetized product in a market that is compounding weekly.WHY IT'S WORTH BUYINGThe hard part is done. Payments, auth, email lifecycle, AI metering, exports, SEO and legal compliance are all live, typically 3 to 6 months of solo build time. The buyer can focus entirely on distribution: the audience lives in public places (X, Reddit, Discord communities, and YouTube tutorials), and every new AI coding tool release is a fresh distribution moment. Obvious growth levers: content and SEO on "make Lovable apps look good" style queries, an affiliate program, per-tool landing pages, a browser extension, and a team plan.Handover includes full repo transfer, domain, database, deployment, and email/payment provider setup guidance.
