Real-Time Apps Powered by Firebase

Firebase shines when you need scale, presence, and push baked in. We build on it without painting you into a corner.

Where Firebase wins

Firebase is excellent for real-time-heavy apps, push-driven workflows, and teams already on Google Cloud. We use it where it shines — chat, presence, IoT — and tell you honestly when something else (like Supabase) would suit better.

What We Build

Firebase projects we deliver

Real-time chat and presence

Firestore + Realtime DB for the kinds of apps where real-time is the product.

Authentication at scale

Email + phone + social + anonymous, with proper security rules and custom claims.

Cloud Functions and triggers

TypeScript functions reacting to writes, schedules, or HTTP requests — for everything DB rules can't express.

Push notifications via FCM

Targeted, deep-linked push with proper opt-in flows and analytics.

Process

How we approach a project

  1. Data shape design

    Firestore is NoSQL — getting the data shape right is half the work. We model query patterns first.

  2. Security rules from day one

    Rules tested with the emulator before any code is written. Public-read bugs don't ship.

  3. Functions and triggers

    Background work goes in Cloud Functions, idempotent and observable.

  4. Cost monitoring

    Budget alerts and per-collection cost dashboards from day one — Firebase bills can surprise you.

Why DEVNIXS

Why pick us for Firebase

Real-time and push are first-class

If your product is presence-driven or push-heavy, Firebase is unmatched.

We get security rules right

Firebase rules are easy to write badly. We test them like code and run them in the emulator on every change.

Honest about cost

We model your read/write patterns up front so you know what month-3 will cost — not just month-1.

FAQ

Common questions

  • Firebase or Supabase?

    Real-time-heavy or push-driven → Firebase. Relational data and SQL → Supabase. Most CRUD apps lean Supabase. We give an honest call based on your use case.

  • How do you keep Firebase costs in check?

    Read/write modelling up front, query indexes, denormalisation where it pays off, and budget alerts that page us before they page you.

  • Can you migrate off Firebase?

    Yes — though it's harder than migrating Supabase. We've done Firestore → Postgres migrations and will scope them honestly.

  • Do you use Firebase Hosting?

    Rarely — Vercel and Cloudflare Pages are usually a better fit for the web layer. Happy to use it if you're already standardised on it.

  • Is Firebase secure enough for finance / health apps?

    Yes, with proper App Check + security rules + Cloud Functions enforcement. We've shipped HIPAA-adjacent apps on it.
