So you started with Supabase Realtime. It was fast. It was easy. It just worked. But now your app is growing. Users want more features. You need better scaling. Or maybe you just want to compare options before going all in.

TLDR: Supabase Realtime is great, but it is not your only choice. Developers often compare Firebase, Pusher, Ably, Hasura, and Appwrite when looking to switch. Each platform has different strengths in scaling, pricing, flexibility, and ease of use. The best option depends on your app size, budget, and how much control you want.

Let’s break down five platforms developers often explore when moving away from Supabase Realtime. Simple. Clear. No fluff.

1. Firebase Realtime Database (and Firestore)

Firebase is usually the first name that pops up. And for good reason.

It is backed by Google. It scales well. It feels mature. Many developers have used it at some point.

Why people consider it:

  • Real-time data sync out of the box
  • Managed infrastructure
  • Strong SDK support
  • Built-in authentication

Firebase Realtime Database streams updates instantly. Firestore also supports real-time listeners. Both are solid choices.

But there are trade-offs.

  • Pricing can grow fast
  • Vendor lock-in is real
  • No SQL support

If you are moving from Supabase because you want SQL flexibility, Firebase might feel limiting. It is NoSQL first. Always.

Still, for mobile apps and startups, it is very popular.

2. Pusher

Pusher is laser-focused on real-time messaging. That is its superpower.

It does not try to be your whole backend. It just handles real-time communication extremely well.

Why developers like it:

  • Simple WebSocket implementation
  • Reliable pub sub system
  • Great docs
  • Works with many stacks

Moving from Supabase Realtime to Pusher can make sense if:

  • You only need real-time events
  • Your database is handled elsewhere
  • You want more predictable scaling for messaging

But remember. Pusher is not a full backend. You will need to manage your own database.

That means more freedom. But also more responsibility.

3. Ably

Ably feels like Pusher’s more global cousin.

It is built for serious real-time systems. Think live dashboards. Multiplayer games. Chat apps at scale.

Why teams compare it:

  • Global edge network
  • Low latency worldwide
  • Strong reliability guarantees
  • Flexible pub sub messaging

Ably shines when performance matters deeply.

If Supabase Realtime feels limiting at scale, Ably becomes attractive. It handles millions of concurrent connections smoothly.

But it can be overkill for small projects.

Also, like Pusher, it focuses on messaging. Not full database management.

You keep your database. Ably handles the real-time layer.

4. Hasura

Now we are talking about SQL lovers.

Hasura sits on top of your PostgreSQL database. It gives you instant GraphQL APIs. And yes, real-time subscriptions.

If you liked Supabase because of PostgreSQL, Hasura feels familiar.

Why developers move toward Hasura:

  • Strong Postgres integration
  • GraphQL subscriptions for real time
  • Fine-grained access control
  • Self-hosting option

Hasura gives you more control. It is closer to the database. That can be powerful.

But it also means:

  • More setup
  • More DevOps work
  • Less plug-and-play magic

If Supabase felt too abstract, Hasura gives you back control.

If Supabase felt easy and you loved that, Hasura might feel heavy.

5. Appwrite

Appwrite is often compared directly with Supabase.

It is open source. It offers real-time APIs. It includes database, auth, storage, and more.

Sounds familiar?

Yes. Very similar philosophy.

Why developers consider it:

  • Open-source core
  • Self-hosting available
  • Structured database model
  • Growing community

If you are moving from Supabase because:

  • You want more control over hosting
  • You prefer a different API structure
  • You want something modular

Appwrite makes sense.

It feels like a sibling platform. Not a total reset.

Quick Comparison Chart

Platform Database Included Real-Time Support Scaling Best For
Firebase Yes (NoSQL) Built-in listeners High, managed by Google Mobile and web apps
Pusher No WebSockets, pub sub Strong for messaging Event-driven apps
Ably No Global pub sub Enterprise-grade High-scale real-time
Hasura PostgreSQL GraphQL subscriptions Depends on setup SQL-focused teams
Appwrite Yes (structured DB) Built-in real-time APIs Moderate to high Open-source backends

How to Choose the Right One

Ask yourself a few simple questions.

1. Do you want a full backend or just real-time messaging?

  • Full backend: Firebase, Appwrite
  • Messaging layer only: Pusher, Ably
  • SQL control: Hasura

2. Do you love SQL?

If yes, avoid pure NoSQL systems unless you are ready to adapt your data model.

3. Do you want to self-host?

  • Yes: Hasura, Appwrite
  • Not really: Firebase, Pusher, Ably

4. Is global low latency critical?

If you are building chat for millions or live multiplayer features, Ably stands out.

Why Developers Leave Supabase Realtime

Supabase Realtime is strong. But no tool fits everyone forever.

Common reasons teams move:

  • Need for more advanced scaling
  • Pricing changes at higher usage
  • Desire for deeper database control
  • Moving toward event-driven architecture
  • Enterprise compliance needs

It is not about “better” or “worse.”

It is about fit.

Tools are like shoes. Great for some journeys. Not for all.

Final Thoughts

Switching real-time platforms feels scary. It touches your core app logic. Your data flow. Your performance.

But it can also unlock growth.

Firebase gives you simplicity. Pusher gives you focus. Ably gives you power. Hasura gives you control. Appwrite gives you open-source flexibility.

The right choice depends on your priorities.

Start small. Test one feature. Measure performance. Compare pricing. Look at developer experience.

Real-time is no longer rare. It is expected. Users want instant updates. Live notifications. Seamless sync.

Luckily, you have options.

And that is a good place to be.
