Build a Social Network App in 21 Days
Feed, profiles, follow graph, messaging — shipped in 3 weeks at a fixed price.
Why Social Network App development is hard to get right
Real-time feed and notifications are technically complex — most freelancers underestimate the scope
Getting a social app into the App Store requires privacy compliance and content moderation tools
No-code tools (Bubble, Adalo) fall apart at scale — your social app needs real infrastructure
Building a follow graph and recommendation feed requires proper database architecture from day one
What we build — in detail
User profiles & authentication
Sign up, onboarding, profile editing, avatar upload, bio — with Supabase Auth under the hood.
Real-time feed
Posts, photos, videos. Chronological v1 — then engagement-sorted in v2. Supabase Realtime handles the live updates.
Follow / friend graph
Follow requests, followers/following count, suggested users. Proper many-to-many schema, not a hack.
Likes, comments, reactions
Engagement layer with notification triggers on every interaction. All optimistically updated on the client.
Real-time 1:1 messaging
DMs between matched/connected users. Delivered in real-time, with read receipts and push notification fallback.
Push notifications
Expo push for mobile — new follower, new like, new message. Configurable per user in notification preferences.
Content moderation tools
Report/block flow, basic admin moderation dashboard. AWS Rekognition for explicit image detection available.

Frequently asked questions
How do you handle real-time at scale?
Supabase Realtime handles social apps up to ~10,000 DAU effortlessly. Beyond that, we upgrade to Ably or Pusher for dedicated WebSocket infrastructure. We design for scale from day one — no architecture rewrites needed.
Can you add a recommendation algorithm?
For MVP, we use chronological feed — it's faster to ship and requires no training data. We add engagement-based ranking (likes, comments, recency weighted) in v2 once you have user data to optimize against.
How do I prevent abusive content?
We build a user report + block flow on day one. AWS Rekognition flags explicit images automatically. Perspective API screens toxic text. An admin dashboard lets you review reports and ban users.
What makes you different from a freelancer for this?
Social apps require real-time infrastructure, mobile expertise, and content moderation — three specialized skill sets. A single freelancer rarely covers all three well. We ship all of this as a single coordinated team in 3 weeks.
