Imagine this: you’re building an app where users expect instant updates—chat messages delivered in milliseconds, dashboards updating without refresh, or collaborative tools that feel alive.
At that moment, the database you choose is not just storage; it’s the heart of your product.
But here’s the catch—do you go with Firebase, Supabase, or Postgres with real-time extensions?
Each promises speed, scalability, and developer happiness, but only one might be the right fit for your project.
Let’s break it down.
1. Firebase – The Veteran in Real-Time
Google’s Firebase is often the first name that pops up when developers think “real-time.”
-
Strengths:
- Blazing fast data sync across devices.
- Massive ecosystem: Authentication, Hosting, Analytics, Push Notifications.
- Great for quick MVPs and startups.
-
Things to Watch:
- Vendor lock-in (you’re tied to Google Cloud).
- Limited SQL-like querying power.
- Pricing surprises if your app suddenly explodes in popularity.

2. Supabase – The Rising Challenger
Supabase has been gaining massive popularity as the “open-source Firebase alternative.” Built on Postgres, it offers both flexibility and the real-time magic developers love.
-
Strengths:
- Powered by Postgres, which means strong relational querying.
- Open-source, with self-hosting options.
- Built-in authentication, APIs, and storage—like Firebase but transparent.
-
Things to Watch:
- Still maturing compared to Firebase’s years of polish.
- Might require more fine-tuning for enterprise-scale workloads.

3. Postgres with Real-Time Extensions – The Underdog That’s Becoming a Titan
Postgres isn’t new—it’s battle-tested, reliable, and one of the most loved databases worldwide. But with extensions like pg_notify, Logical Replication, or tools like Hasura and Postgres-ML, it’s stepping into the real-time game too.
-
Strengths:
- Full SQL power—joins, transactions, advanced queries.
- Enterprise-level reliability and control.
- Extremely customizable with extensions.
-
Things to Watch:
- Requires setup and expertise; not plug-and-play like Firebase.
- You’ll often need third-party tools for full real-time support.
👉 Want to experiment? Here’s a quick example using pg_notify:
-- Listen to a channel
LISTEN new_messages;
-- Trigger a notification
NOTIFY new_messages, 'Hello, world!';
This allows apps to listen to DB events in real-time. Pair it with Node.js or Hasura, and you’ve got a powerful stack.
More details in the Postgres Notify docs.
So, Which One Should You Choose?
- If you need to ship fast and focus on features → Firebase.
- If you want freedom + modern dev experience → Supabase.
- If you need ultimate control + enterprise power → Postgres with extensions.
No one-size-fits-all. The key is to match your project’s needs, budget, and long-term goals with the right tool.
Final Thoughts
Real-time databases are no longer a luxury—they’re a requirement for apps in 2025. Whether you’re building a chat app, fintech dashboard, or multiplayer tool, your choice today will decide how far your product can scale tomorrow.
