Firebase vs PlanetScale
Firebase is Google's backend-as-a-service platform, combining a NoSQL database with authentication, hosting, serverless functions and analytics in one product with a free tier. PlanetScale is a managed database platform built by the creators of Vitess, historically known for serverless MySQL with branching and non-blocking schema changes, and now also offering managed Postgres, with no free plan but pay-as-you-go pricing from around $5 a month. Choose Firebase if you want a full NoSQL backend platform with a free tier; choose PlanetScale if you need managed relational MySQL or Postgres with schema branching and Vitess-grade scaling.

What's the difference between Firebase and PlanetScale?
Firebase bundles a NoSQL database with authentication, hosting and functions in one
Firebase bundles a NoSQL database with authentication, hosting and functions in one Google platform; PlanetScale is focused purely on the database layer, built around Vitess for MySQL and also offering managed Postgres, with auth and hosting left to other services.
PlanetScale's signature features are database branching and non-blocking schema changes, letting teams
PlanetScale's signature features are database branching and non-blocking schema changes, letting teams evolve relational schemas safely; Firebase's flexible NoSQL model generally avoids formal schema migrations altogether.
Firebase has a free Spark plan with fixed usage limits and no
Firebase has a free Spark plan with fixed usage limits and no payment method required; PlanetScale has no free plan, with pay-as-you-go pricing starting around $5 a month for a small Postgres instance.
PlanetScale's core scaling technology, Vitess, is open source and was originally built
PlanetScale's core scaling technology, Vitess, is open source and was originally built at YouTube to shard MySQL at scale; Firebase's infrastructure is entirely proprietary to Google.
Firebase vs PlanetScale pricing
Firebase's Spark plan is free with fixed usage limits; Blaze bills usage beyond those limits. PlanetScale has no free plan: its Base plan is pay-as-you-go, starting around $5 a month for a small Postgres instance.
Firebase
Spark (free): 1 GiB Firestore storage, 50,000 daily reads, 20,000 daily writes, 10 GB hosting. Blaze: pay-as-you-go on top, e.g. Cloud Functions $0.40 per million invocations beyond 2M free.

Should you choose Firebase or PlanetScale?
Choose Firebase if
- You want a NoSQL database plus auth, hosting and functions from one provider, with a genuine free tier
- You're building a mobile or web app that benefits from Firestore's realtime sync
- You don't need relational schema branching or migrations
- You want Google Cloud billing and infrastructure
Choose PlanetScale if
- Your data is relational and needs MySQL or Postgres specifically
- You want database branching and non-blocking schema changes for safer migrations
- You expect to scale to high traffic and want Vitess-grade sharding underneath
- You're comfortable with no free tier and pay-as-you-go pricing from the start
Switching between Firebase and PlanetScale
Moving from Firebase to PlanetScale means converting NoSQL documents into relational tables and schemas, and adding a separate auth provider and hosting service since PlanetScale doesn't include either. Moving from PlanetScale to Firebase means denormalizing relational schemas into documents and gaining built-in auth and hosting, while losing PlanetScale's branching and non-blocking schema change workflow.
Firebase vs PlanetScale: common questions
Does PlanetScale have a free plan?
No. PlanetScale removed its free tier and now runs entirely on pay-as-you-go pricing, starting around $5 a month for a single-node Postgres instance, with no monthly minimum contract on the Base plan.
What is Vitess and why does it matter for PlanetScale?
Vitess is an open source sharding system originally built at YouTube to scale MySQL horizontally. PlanetScale was built by Vitess's creators and uses it to power its managed MySQL offering, and now applies similar scaling technology to its managed Postgres.
Does Firebase support relational data like PlanetScale?
Firebase's Firestore and Realtime Database are NoSQL and don't support relational joins the way MySQL or Postgres do. Structured relational data generally fits PlanetScale better.
Can I self-host either of these?
PlanetScale's underlying Vitess technology is open source (Apache-2.0), though the managed PlanetScale service itself is proprietary. Firebase is entirely proprietary with no self-hosting option.
Does PlanetScale include authentication?
No. PlanetScale is a database service only; you'd need a separate authentication provider, unlike Firebase which includes Firebase Authentication built in.
