Quick Verdict
If you need a drop-in MySQL-compatible serverless database with zero-downtime schema changes, PlanetScale is your best bet. If you want Postgres with instant branching and scale-to-zero, go with Neon. And if you need a full backend-as-a-service (database + auth + storage + realtime) on Postgres, Supabase is the obvious winner.
For most indie hackers and small teams building new projects in 2026, I recommend Neon as the default serverless Postgres – it’s fast, cheap, and branching is a standout option. But if you’re already using Supabase for its other features, stick with it – the database is solid.
Comparison Overview
Serverless databases have matured a lot. The three big names – PlanetScale, Neon, and Supabase – each take a different approach to scaling Postgres or MySQL without managing servers.
- PlanetScale – MySQL-compatible, built on Vitess. Focuses on branching and zero-downtime schema migrations.
- Neon – Postgres-compatible, uses compute-compute separation with instant branching and scale-to-zero.
- Supabase – Postgres-compatible, open-source Firebase alternative with built-in auth, storage, realtime, and Edge Functions.
All three offer free tiers, branching, and connection pooling. But the devil is in the details: pricing, ecosystem, and lock-in.
What Is PlanetScale?
PlanetScale launched in 2021 as a serverless MySQL database. It’s built on top of Vitess (the same tech that powers YouTube’s MySQL sharding). The killer feature is database branching – you can fork your production database instantly, Make schema changes in a branch, then merge with zero downtime.
PlanetScale uses a deploy request workflow similar to GitHub pull requests. You create a branch, make changes, and open a deploy request. The platform safely applies the schema migration without locking tables or causing downtime. This is huge for teams that can’t afford maintenance windows.
It also includes a connection pooler (pScale Proxy) that handles thousands of concurrent connections. The free tier gives you 1 database, 1 branch, 5GB storage, and 10 million row reads per month. Paid plans start at $39/month for 1GB RAM, 10GB storage, and 100 million row reads.
Under the hood: MySQL 8.0, with some limitations (no foreign keys, no full-text search, no triggers – due to Vitess sharding limitations). If you need those features, look elsewhere.
PlanetScale is best for teams that want MySQL compatibility plus Git-like branching for schema changes.
What Is Neon?
Neon is a serverless Postgres database that launched in 2022. It uses a compute-compute separation architecture: storage is separate from compute, and compute nodes can scale to zero when idle. This means you pay only for the compute time you use (similar to AWS Lambda).
The standout feature is instant branching – you can create a branch of your database in milliseconds, even for terabytes of data. Branches are copy-on-write, so they don’t duplicate storage. This is incredible for development, testing, and CI/CD.
Neon also includes a built-in connection pooler (PgBouncer-based) and support for Pgvector for AI workloads. It’s fully Postgres-compatible – all extensions, indexes, and SQL features work.
The free tier gives you 500MB storage, 100 hours of compute per month, and unlimited branches. Paid plans start at $19/month for 3GB storage and 300 compute hours. You can also pay-as-you-go for compute.
Neon’s branching is more flexible than PlanetScale’s because it’s truly instant and doesn’t require a separate schema migration workflow. You can branch at any point in time (point-in-time branching) and even create read-only replicas.
What Is Supabase?
Supabase started in 2020 as an open-source Firebase alternative. It provides a full Postgres database plus authentication, storage, realtime subscriptions, Edge Functions, and a dashboard. The database is just one piece of the puzzle, but it’s a very good piece.
Supabase uses managed Postgres with a connection pooler (Supavisor) and supports pgvector, PostGIS, and other extensions. It also has Row-Level Security built in, so you can define access policies directly in the database.
The free tier is generous: 500MB database, 2GB bandwidth, 50,000 monthly active users for auth, 1GB file storage, and 2 million realtime messages. Paid plans start at $25/month for 8GB database and 50GB bandwidth.
Supabase’s branching is still in beta as of 2026, but it’s available. It’s not as polished as Neon’s or PlanetScale’s, but it works for development previews.
The real value of Supabase is the ecosystem. You get a database, auth, storage, and realtime in one product. Many indie hackers use it as a complete backend.

Key takeaway: PlanetScale is MySQL-only with some missing SQL features. Neon is pure Postgres with excellent branching. Supabase is Postgres plus a full backend.
Pricing Comparison
| Tier | PlanetScale | Neon | Supabase |
|---|---|---|---|
| Free | 5GB storage, 10M row reads, 1 branch | 500MB storage, 100 compute hours, unlimited branches | 500MB database, 2GB bandwidth, 50K MAU |
| Pro | $39/month: 10GB storage, 100M row reads | $19/month: 3GB storage, 300 compute hours | $25/month: 8GB database, 50GB bandwidth |
| Team | $99/month: 100GB storage, 1B row reads | $49/month: 10GB storage, 750 compute hours | $75/month: 16GB database, 200GB bandwidth |
| Enterprise | Custom | Custom | Custom |
Important notes:
- PlanetScale’s pricing is based on row reads and storage – not compute. This can be unpredictable if your app has many small queries.
- Neon charges for compute hours. The free 100 hours is enough for a small app, but if you leave a connection open 24/7, you’ll burn through it quickly. Use connection pooling and scale-to-zero to save.
- Supabase’s pricing is based on database size and bandwidth. The free tier is generous for auth and storage, but the database limit is small.
For a typical indie app with 10,000 daily active users, expect to pay around $25–$40/month on any of these platforms.

- You don’t mind paying a bit more for the convenience of an all-in-one platform.
Best for: Full-stack developers who want to move fast without managing separate auth, storage, and database providers. Also great for prototypes and MVPs.
Final Verdict
After using all three platforms extensively in 2026, here’s my honest take:
If you’re starting a new project today, go with Neon. It gives you full Postgres, instant branching, scale-to-zero, and fair pricing. The only reason not to is if you need the extra services that Supabase provides.
If you need a complete backend and don’t want to piece together auth + storage + database, Supabase is a fantastic choice. Just be aware that you’re paying for the convenience, and branching is not as mature.
If you’re a MySQL shop and need zero-downtime migrations, PlanetScale is still the best in class. But I’d only pick it if you’re already committed to MySQL – otherwise, Postgres is more versatile.
My winner: Neon – it’s the most developer-friendly serverless Postgres in 2026. The combination of branching, scale-to-zero, and full Postgres compatibility is hard to beat. And it’s open source, so you’re not locked in.
FAQ
Can I use these databases with Vercel or Railway?

Which one is best for a side project on a budget?
Neon’s free tier with scale-to-zero is the cheapest for low-traffic apps. Supabase’s free tier is also generous but you pay for compute even when idle.
Can I self-host any of these?
Supabase and Neon are open source and can be self-hosted. PlanetScale is proprietary.
Do any of them support PostGIS?
Neon and Supabase support PostGIS. PlanetScale does not.
How do they handle connection limits?
All three have built-in connection poolers. PlanetScale uses pScale Proxy, Neon uses PgBouncer, Supabase uses Supavisor. They handle thousands of concurrent connections easily.
Which one is best for AI/vector search?
Neon and Supabase both support pgvector. PlanetScale does not support vector extensions.
Can I migrate from one to another?
Yes, since all use standard SQL, you can dump and restore. But if you use Supabase’s auth or storage, you’ll need to migrate those separately. Neon and PlanetScale are just databases.
What about GitHub integration?
PlanetScale has a native GitHub integration for deploy requests. Neon and Supabase work with GitHub Actions for CI/CD. You can also use GitHub to host your code and trigger database branching.
