Supabase is a powerful Postgres-based BaaS, but it's not the right fit for every project. Whether you're hitting cost walls at scale, want to avoid vendor lock-in, or need a NoSQL or MySQL foundation, there are strong alternatives. We compare Neon, Firebase, Appwrite, PlanetScale, and PocketBase across the dimensions that actually matter.
supabase made backend-as-a-service cool again by wrapping Postgres in a slick real-time layer. but it's not the only game in town — and depending on your stage, stack, or scale, one of these five alternatives might serve you better.
here's who this guide is for: you're building something real, you've outgrown (or never wanted) supabase's particular trade-offs, and you want a clear, source-backed comparison before you commit.
| Product | Database Engine | Hosting Model | Best For |
|---|---|---|---|
| Neon | Postgres (serverless) | Managed cloud | Devs who love Postgres but want scale-to-zero |
| Firebase | Firestore (NoSQL) | Managed cloud | Google ecosystem shops, real-time apps |
| Appwrite | MariaDB/Postgres/MySQL | Self-hosted or cloud | Open-source fans who want full control |
| PlanetScale | MySQL (serverless) | Managed cloud | MySQL lovers who need non-blocking schema changes |
| PocketBase | SQLite | Self-hosted (single binary) | Solo devs and tiny projects |
if your problem with supabase isn't postgres itself but the bundled extras you're paying for, neon strips it back to a serverless postgres that scales to zero when idle1. you get branching for instant dev databases, a generous free tier (10 GB storage, 100 compute hours/month), and no vendor lock-in beyond standard postgres tooling.
why switch: you're paying supabase for auth, storage, and real-time but only using the database. neon is cheaper at moderate scale and your existing postgres tooling (pgAdmin, psql, prisma) works unchanged.
trade-off: you'll need to bring your own auth and storage layer. no built-in real-time subscriptions.
firebase is supabase's closest conceptual competitor, but built on nosql (firestore) rather than postgres2. it's deeply integrated with google cloud — cloud functions, cloud storage, firebase auth, and crashlytics all snap together.
why switch: you're already in the google ecosystem, you need real-time sync across web + mobile, or your data model is naturally document-oriented.
trade-off: firestore queries are limited compared to postgres joins. cost can explode at scale (document reads add up fast). vendor lock-in is real — migrating away from firebase is painful.
appwrite gives you supabase's feature set (auth, database, storage, functions, real-time) but as open-source software you can self-host on your own infrastructure3. it supports multiple database backends including mariadb, postgres, and mysql.
why switch: you want the supabase feature set without vendor lock-in. you're comfortable running your own server and want full data sovereignty.
trade-off: self-hosting means you own the ops burden. the cloud tier is newer and less battle-tested than supabase or firebase.
planetscale is the mysql answer to neon: a serverless mysql database with branching, non-blocking schema changes (no more ALTER TABLE locking your production DB), and a generous free tier4.
why switch: your team knows mysql, not postgres. you need safe schema migrations at scale. you want vitess-level horizontal scaling without managing vitess yourself.
trade-off: mysql has weaker json support than postgres. planetscale doesn't offer built-in auth, storage, or real-time — it's a database, not a baas.
pocketbase is a single binary that bundles sqlite + a real-time api + auth + file storage + a dashboard ui5. it's absurdly simple to deploy — download one file, run it, done.
why switch: you're a solo dev or building a prototype. you want something that fits in a 20mb binary and runs on a $5 vps. you don't need multi-region replication yet.
trade-off: sqlite doesn't scale to concurrent writes at production traffic. no built-in migration tooling. not suitable for multi-server deployments.
| Your Situation | Best Pick | Why |
|---|---|---|
| Prototyping / solo project | PocketBase | One binary, zero config, sqlite is fine for low traffic |
| Postgres devs, moderate scale | Neon | Serverless postgres, scale-to-zero, familiar tooling |
| MySQL shop, need safe migrations | PlanetScale | Non-blocking schema changes, vitess-powered scaling |
| Need full BaaS, want self-host | Appwrite | Open-source supabase alternative, run it yourself |
| Google ecosystem / real-time mobile | Firebase | Firestore sync, cloud functions, google auth |
supabase is excellent — but it's not the only excellent option. the best database backend is the one that matches your data model, your team's expertise, and your scale trajectory.
if you're postgres-first and cost-conscious, go neon. if you need a full baas without lock-in, try appwrite. if you're prototyping, pocketbase will get you to mvp faster than anything else. and if your team speaks mysql, planetscale is the grown-up choice.
