La Consignerie - Bubble to Next.js Migration

The Challenge

La Consignerie had built a successful circular economy marketplace on Bubble, growing to 5,000+ active users and 12,000+ listed products. But the platform was buckling under load: pages took 4-6 seconds to load, search was unreliable, and their monthly Bubble bill had climbed to €600.

Our Approach

Having built 40+ Bubble apps ourselves, we knew exactly how to map Bubble’s architecture to a modern stack:

1. Schema Redesign - Converted Bubble’s flat data structure to a normalized PostgreSQL schema
2. Feature Parity - Rebuilt all marketplace workflows (listings, search, chat, payments) in Next.js
3. Payment Migration - Moved from Bubble’s Stripe plugin to native Stripe Connect for proper marketplace payouts
4. Data Transfer - Automated migration scripts handled 12,000+ products and all user accounts
5. Zero-Downtime Cutover - Ran both systems in parallel for 48 hours before switching DNS

Results

The new platform launched with zero downtime. Page loads dropped from 4.6s to 0.8s, hosting costs fell by 85%, and conversion rates increased 45% in the first month due to the improved user experience.
