FlashFeed — Posts that race the clock

Social feeds are broken. Everything lives forever, nothing feels urgent, and the algorithm decides what matters.

FlashFeed flips that.

Every post starts with a 24-hour countdown timer. Likes add time. Comments add more. Shares add even more. If your post gets ignored — it

self-destructs. Forever.

No ghost posts. No graveyard of old takes. Just a feed that stays alive and relevant.

What I built:

- ⏱ Real-time countdown timer on every post (Supabase Realtime)

- ❤️ Likes (+15 min), 💬 Comments (+30 min), ↗️ Shares (+45 min)

- 🔔 Push notifications before your post expires

- 🔍 User search + follow system + personal feed

- 📱 Installable PWA — works on iOS and Android

Stack: Next.js 15 App Router · Supabase · Firebase Auth · Tailwind CSS · Vercel

Built this as an experiment in ephemeral social — where attention is the currency and every post is a bet.

Would love feedback from the community — especially on the timer mechanics. Is 24h too long? Too short? What interaction should rescue a post the most?
