Why look beyond Supabase?
Supabase earned its reputation fairly. A managed Postgres database, auto-generated REST and GraphQL APIs, row-level-security auth, storage, and edge functions wrapped in a polished dashboard is a genuinely great developer experience. For a lot of projects it is the right answer, and I'd never tell you to switch away from something that works.
But "backend-as-a-service" is an opinionated bundle, and those opinions don't suit everyone. The most common reasons teams I talk to go looking for alternatives in 2026:
- You want your *own* backend, not generated APIs. If you're shipping a FastAPI, Rails, or Spring Boot service, the auto-generated PostgREST layer is something you bypass anyway.
- You need more than Postgres. MySQL, MongoDB, or Redis aren't first-class in the Supabase model.
- Vendor lock-in concerns. RLS-as-authorization and the Supabase client SDK can become load-bearing in ways that are hard to unwind.
- You want app hosting and database in one place. Supabase is the data layer; you still host your app somewhere else.
This post is a fair survey, not a hit piece. Let's look at the real options.
The contenders
| Platform | Best for | Database(s) | Hosts your app too? | Open source core |
|---|---|---|---|---|
| Supabase | Postgres-first BaaS with auth/storage | Postgres | No (functions only) | Yes |
| Firebase | Realtime mobile apps, Google ecosystem | Firestore, RTDB | Functions/Hosting | No |
| Appwrite | Self-hostable BaaS | MariaDB-backed | Functions | Yes |
| Neon | Serverless Postgres with branching | Postgres | No | Partially |
| PlanetScale | Serverless MySQL at scale | MySQL (Vitess) | No | No |
| PandaStack | App + DB in one platform | Postgres, MySQL, MongoDB, Redis | Yes | No |
Firebase
The original BaaS. Firestore's realtime listeners and offline sync are still best-in-class for mobile, and the Google Cloud integration is deep. The trade-offs are well known: it's a document store (not relational), querying is restrictive, and costs can surprise you at scale. If you're building a chat or collaborative mobile app and don't need SQL, Firebase remains a strong default.
Appwrite
If the appeal of Supabase is "open source BaaS I can self-host," Appwrite is the most direct competitor. Auth, databases, storage, functions, and messaging in a self-hostable package. It's matured a lot. The trade-off versus Supabase is that you're not getting raw Postgres underneath in the same way, so portability of your data model looks different.
Neon and PlanetScale
These aren't BaaS platforms; they're *database* platforms, and that's exactly the point for many teams leaving Supabase. Neon gives you serverless Postgres with instant database branching, which is fantastic for preview environments. PlanetScale gives you horizontally scalable MySQL on Vitess with non-blocking schema changes. Pick these when the database is the thing you care about and you'll host the app yourself.
Where PandaStack fits
I'll be upfront: I build PandaStack, so read this section with that in mind. PandaStack takes a different angle from Supabase. Instead of generating a backend for you, it runs *your* backend and *your* database side by side and wires them together automatically.
When you connect a Git repo, PandaStack:
- 1Detects your framework (or uses your Dockerfile), builds with rootless BuildKit in an ephemeral Kubernetes Job, and deploys via Helm.
- 2Provisions a managed database when you add one — PostgreSQL (14.x/16.x), MySQL (5.7/8.x), MongoDB, or Redis.
- 3Injects
DATABASE_URLinto your app automatically, so there's no copy-pasting connection strings.
# Your app reads the injected env var — nothing to configure
export DATABASE_URL="postgresql://..." # provided by PandaStackThe philosophy is "Push code. It runs." — you own the backend code, PandaStack owns the infrastructure. That's the opposite trade from Supabase, where the platform owns the backend shape and you write less code.
Honest limits: PandaStack is a newer platform and the ecosystem is still growing. There's no built-in auth/storage/auto-API layer the way Supabase ships it — if you want PostgREST-style instant APIs out of the box, Supabase is genuinely better at that specific job. Free-tier databases are sized for dev/hobby use, and free-tier apps cold-start on preemptible nodes.
How to choose
- You love the BaaS model and Postgres -> stay on Supabase, or self-host Appwrite for full control.
- Realtime mobile, document data -> Firebase.
- You just need a great serverless database -> Neon (Postgres) or PlanetScale (MySQL).
- You're writing your own backend and want app + DB managed together -> PandaStack.
A migration sanity check
If you do migrate off Supabase's data layer, the good news is the Postgres data itself is portable:
pg_dump "$SUPABASE_DB_URL" -Fc -f backup.dump
pg_restore -d "$NEW_DB_URL" backup.dumpThe parts that *don't* travel are RLS policies used as your auth layer, Supabase Auth users, and any reliance on the Supabase client SDK. Budget time to reimplement those in your own app code. That's the real cost of leaving a BaaS, and it's worth knowing before you start.

If the "own your backend, let the platform run it" model sounds right, PandaStack's free tier gives you 5 web services, a managed database, and edge functions to try it end to end. Spin something up at [dashboard.pandastack.io](https://dashboard.pandastack.io).
