DevLaunch Kit is a complete AI-powered product launch pipeline that turns a one-sentence idea into a ready-to-launch digital product in minutes. Built for indie developers and solopreneurs, it combines market analysis, landing page generation, payment setup, and a full digital product marketplace — all in one Next.js 15 application.
Core Pipeline: Enter your product idea → AI analyzes market demand (search volume, competitors, pricing) → generates a conversion-optimized responsive landing page → sets up Creem payment integration → packages everything as a downloadable ZIP with full source code.
Digital Store: Sell Notion templates, AI prompt packs, code templates, and design assets with one-time purchases, secure token-based downloads, and automated email delivery.
Admin Dashboard: Full back-office with product/order/blog/subscriber management, revenue analytics, page view tracking, conversion rate metrics, and CSV exports.
