BuyBye! - Shared grocery lists. No account. Works offline. Free.

Hey Product Hunt 👋 I'm Isac, the maker of BuyBye. I built this because every shopping list app I tried wanted me to do three things before I could add "milk" to a list: create an account, install something from a store, and decide between a free tier with ads on the list itself or a $4/month subscription to unlock basic sharing. For a shopping list. With my partner. So BuyBye does the opposite of all that: Open the link, start typing. No account, no install — the list lives on your device. Want to share or sync across phones? Sign up in 5 seconds (still free). Then send your partner a link, both phones stay in real-time sync — iPhone, Android, laptop, whatever's in your hand. Auto-categorized. Type "yogurt", it lands under Dairy. Type "leche" or "leite" — same thing. 7 languages, including voice input. Offline-first. It's a PWA. Edits queue and merge when you're back online. No feature gates. Sharing, recipes-to-list, meal planner, voice input — all free. The optional $0.99/mo only removes the ad banner. Nothing else is locked. Everything you see was built solo with React + Vite + Supabase. The whole thing is a single PWA at getbuybye.com — no store install, no waiting for review. Things I'd love feedback on: The "no account" onboarding — does it feel like trust or like the data will vanish? Auto-categorization quality in your language — wrong category? tell me the item and I'll fix it. Anything you'd expect to find that's missing. I'm here all day, replying to every comment. Thanks for taking a look 🙏 — Isac
