[itsyogesh]

Summary

This PR introduces the complete strategic and technical documentation for Projectwise 2026, a platform modernization initiative that pivots from a design-focused directory to a comprehensive marketplace connecting commercial-ready open source software with verified experts and entrepreneurs.

Key Changes

• Strategic Vision: Documented the evolution from the original 2017 Projectwise (design-focused) to the 2026 version (business-focused), targeting the $600B+ WordPress ecosystem opportunity
• Platform Architecture: Defined a single Next.js 15 + Payload CMS 3.0 application (revised from two-repo approach) deployed on Vercel with PostgreSQL backend
• Data Model: Specified complete TypeScript interfaces for core collections including Projects, Ideas, Categories, Experts, Jobs, and Interest Forms
• Feature Roadmap: Outlined 4-phase launch plan (MVP Directory → Expert Network → Job Board → Operator Dashboard) with specific pages and functionality
• Content Strategy: Defined approach for 100+ curated projects with automated screenshot capture and GitHub stats integration
• SEO Strategy: Planned 200+ programmatic pages using category, alternative, license, and use-case templates for organic growth
• Business Ideas Feature: Added new "Ideas" section showing 300+ business opportunities for each white-label platform (inspired by Ideabrowser's success)
• Revenue Model: Outlined 5-phase monetization path from free MVP through sponsorships, job board, expert subscriptions, and revenue sharing
• Launch Plan: Detailed 2-week pre-launch preparation and week-of launch strategy across Product Hunt, HN, Twitter, Reddit, and Dev.to
• Project Seed List: Curated 100 open source projects across 3 tiers (Tier 1: white-label ready, Tier 2: operator-friendly, Tier 3: technically possible)

Notable Implementation Details

• Single App Architecture: Payload CMS 3.0 now installs directly into Next.js /app folder, eliminating need for separate backend server and simplifying deployment to Vercel
• Cost Efficiency: MVP deployable for ~$10/year (domain only) using Vercel free tier, Neon PostgreSQL free tier, and Vercel Blob storage
• Built-in Auth: Leveraging Payload's native authentication with GitHub OAuth via Auth.js plugin, no separate auth service needed
• Programmatic SEO: 400-500+ auto-generated pages targeting long-tail keywords for organic growth (following OpenAlternative's proven playbook)
• Automation: Screenshot capture via ScreenshotOne API, GitHub stats syncing, and contributor profile linking for minimal manual content management

Validation & Inspiration

• Validated market opportunity through OpenAlternative's success (100k visitors week 1, 1M+ annually, $3.5k/month revenue)
• Inspired by Ideabrowser's business ideas feature (669K visits, 704% growth in July 2025)
• Addresses documented open source maintainer crisis (60% unpaid, 44% burnout)
