I built a crowdsourced deals + map app for Vietnam in 6 months — stack, traffic, and what broke
A developer created a crowdsourced map app for cheap dining and shopping in Vietnam within six months. The app, cheap-map.app, allows users to submit prices and aggregates deals from various merchants. The developer shared insights on the technology stack used and challenges faced during the build process.
- ▪The app aims to help locals and tourists find affordable food and shopping options in Vietnam.
- ▪The technology stack was chosen to keep operational costs under $30 per month at 1,000 users per day.
- ▪The developer encountered issues with Vercel's ISR Writes, which were resolved by adjusting caching settings.
