How I Built a Wedding Planning Suite with Supabase in 3 Months
How I Built a Wedding Planning Suite with Supabase in 3 Months Quick Answer: I built a full wedding planning platform in 90 days using Supabase as the backend (PostgreSQL database, real-time subscriptions, Row Level Security, and OAuth auth), Next.js 14 for the frontend, and a few carefully chosen npm packages for specific features like QR code scanning. The key was leveraging Supabase's managed services to avoid building auth, websockets, and file storage from scratch. Introduction Three months ago, I had an idea: what if couples could plan their entire wedding through one cohesive platform? Not a static checklist app, but a living, breathing system where vendors, guests, budgets, and timelines all talked to each other in real time. I'm a solo developer with a day job. I didn't have a team of backend engineers to build authentication, real-time sync, or file storage infrastructure. I needed a stack that would let me ship fast without shipping broken. Enter Supabase. I'd heard the "Firebase alternative" pitch before, but what I discovered was something far more powerful for developers who actually want to own their data and their SQL. This is the story of how I built WedPlanner—a full wedding planning suite—with Supabase, Next.js, and a few other tools. No VC funding. No offshore team. Just me, a tight deadline, and a PostgreSQL database that never let me down. Why Supabase? The Architecture Decision That Made Everything Possible When you're building alone, every architectural decision compounds. Pick the wrong database, and you'll spend weeks fighting migrations. Pick the wrong auth solution, and you'll ship with security holes you don't even know about. I evaluated Firebase, PlanetScale, Clerk, and rolling my own PostgreSQL on RDS. Here's why Supabase won: PostgreSQL, not a proprietary document store. Wedding data is relational. A guest belongs to a wedding. A vendor has multiple bookings. A budget category has many line items.
