Frynz – Social Networking in Echtzeit

Aufgabe
Frynz wollte eine Social‑App, die spontane Treffen, Gruppen‑Chats und Live‑Events ohne spürbare Latenz ermöglicht – inklusive Push‑Benachrichtigungen, Karten‑Clustering und DSGVO‑konformer Datenspeicherung.

Unsere Supabase‑Lösung
Wir setzten auf eine Supabase‑Instanz (PostgreSQL‑Core) als Realtime‑Backend. Row‑Level‑Security und WebSocket‑Subscriptions skalieren Feed, Chat und Reaktionen horizontal, können aber bei Bedarf on‑premise betrieben werden. Flutter‑ und React‑Clients greifen über Supabase‑SDKs zu, Edge‑Functions übernehmen Geschäftslogik.

Ergebnis
Beim Launch verarbeitet Frynz > 50 000 Echtzeit‑Events Minute, läuft kostengünstig auf managed Supabase – kann aber jederzeit in eine Self‑Hosting‑Variante wechseln. Die App wird deutschlandweit eingesetzt.
