What you can build with Koffan
Koffan is a self-hosted shopping list web application built for couples, families, and shared households. It syncs in real time between phones, tablets, and desktops over WebSockets, works offline as a Progressive Web App, and organizes products into custom sections with fuzzy auto-complete drawn from your own purchase history.
Self-hosting Koffan on a VPS keeps the household grocery list on infrastructure you control instead of a shopping SaaS. Written in Go with an embedded SQLite database, it runs in roughly 2.5 MB of RAM with a 16 MB disk footprint, ships with translations for thirteen languages, includes brute-force login protection, and exposes an optional REST API for automations, migrations, and integrations.
Key features of Koffan
Real-time sync
WebSocket-backed live updates keep every household member on the same list as items are added, checked, or edited.
Offline PWA
Install to your phone home screen and keep adding or checking off items with no connection — changes sync when back online.
Multiple lists
Create separate lists per store or purpose with custom icons, and reuse product sections like Dairy, Vegetables, or Cleaning.
Ultralight footprint
Written in Go on a SQLite backend — around 16 MB on disk and 2.5 MB of RAM, ideal for even the smallest VPS plan.
Smart auto-complete
Fuzzy search suggests products from your past shopping history and remembers which section each item belongs to.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Kodee and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
