Rental marketplace boilerplate with clean flag-driven architecture, but Supabase+Stripe templates exist.

Strengths

•Config-driven feature flags cleanly remove nav/API routes/context—forces good modular design
•Live demo with 50+ listings proves functional end-to-end
•Socket.io + Prisma stack is straightforward for any Next.js dev to extend

Weaknesses

•Marketplace boilerplate is a crowded category; no differentiation from Shipfa, Saleor, or DIY Supabase stacks
•One-time purchase model limits iteration feedback and ongoing support

Post Description

I've built three rental marketplaces from scratch. The painful parts were always the same — real-time messaging that actually works (read receipts, unread counts, email fallback), reservation systems with availability calendars and conflict detection, mutual review systems, and the endless admin panel.

Third time around I stopped and extracted everything into a single boilerplate. The key design decision was making it config-driven — nine feature flags, TypeScript config files for pricing (hourly/daily/weekly/monthly), categories, theme, emails. Flip a flag and the entire feature disappears cleanly, including nav links, context providers, and API routes.

Stack: Next.js 15 App Router, Tailwind v4, Prisma + PostgreSQL, Socket.io, Cloudflare R2. Nothing exotic — any Next.js developer can read the codebase in an afternoon.

Selling it as a one-time purchase. Happy to talk about the architecture or any of the trade-offs I made.
