Tech stack for Social / community app
9 layers, picked for your answers. Boring where it should be, so your effort goes into the product.
- Realtime on mobile: design for flaky connections, with reconnects and offline-safe state.
- Mobile
React Native with Expo
One codebase for iOS and Android. Expo handles builds, signing and over-the-air updates, so a small team can ship both platforms.
- What would change my mind
- Heavy graphics, AR, or deep hardware integration, where native code earns its cost.
- Alternative
- Flutter
- Backend / API
Separate TypeScript API service (Node.js + Fastify)
A dedicated service you can scale, monitor and audit on its own, sharing TypeScript types with the frontend.
- What would change my mind
- An early MVP with modest traffic, where Next.js route handlers inside the web app are enough.
- Alternative
- NestJS, or Go for a hot path
- Database
PostgreSQL (managed: Neon or AWS RDS)
Relational, transactional and boring. JSON columns cover the semi-structured bits, and pgvector covers embeddings if you add AI.
- What would change my mind
- Truly schemaless, write-heavy event data at very high volume. Add a specialised store for that slice only.
- Alternative
- MySQL, or MongoDB for document-shaped data
- Auth
Clerk
Prebuilt sign-in UI, organisations, roles and MFA. Hours instead of weeks for a B2B-ready login.
- What would change my mind
- Per-user pricing at consumer scale, or a hard requirement to keep auth in-house.
- Alternative
- Auth.js (NextAuth)
- Hosting
Vercel
Git push to deploy, preview URLs for every branch and no servers to manage, which is exactly what an MVP team needs.
- What would change my mind
- Long-running processes, heavy compute or strict data-residency requirements.
- Alternative
- Netlify, or Railway for a container
- Realtime
Pusher Channels or Ably
Managed WebSockets: add live updates and presence without operating connection servers.
- What would change my mind
- Very high message volume, where pricing pushes you to run your own.
- Alternative
- Socket.IO on your API service
- Background jobs
Inngest or Trigger.dev
Durable background functions with retries, schedules and a dashboard, written in the same TypeScript codebase.
- What would change my mind
- Very high throughput or strict data residency, which points to a queue in your own cloud.
- Alternative
- BullMQ + Redis
- Analytics
PostHog
Product analytics, funnels, session replay and feature flags in one tool, with a generous free tier.
- What would change my mind
- A marketing-only site, where a simple privacy-friendly counter like Plausible is enough.
- Alternative
- Plausible (simple), or Mixpanel
- Email
Resend
Reliable transactional email with a clean API and good deliverability defaults.
- What would change my mind
- Marketing campaigns and newsletters, which belong in a separate tool.
- Alternative
- Postmark
This is the stack I'd pick.

What makes a social / community app different
Social apps are shaped by feeds, notifications and moderation. The feed's data model and the moderation tooling matter more than any single screen.
Risks to plan for
Feed performance
Feeds that are fast at 100 users crawl at 100,000. Plan fan-out and pagination early.
Moderation
App stores require reporting and blocking for user-generated content before launch.
Notification spam
Too many pushes and users mute you. Build preferences and batching from the start.
