Postgres, MySQL, or Serverless: Choosing a Managed Database
Database branching, scale-to-zero, and NoSQL flexibility solve different problems. This guide breaks down which managed database fits which kind of project.
Managed database platforms used to differ mainly on uptime SLA and price. Today the real differentiator is workflow: whether the platform lets you branch your schema like code, scale to zero between bursts of traffic, or hands you a full backend rather than just a connection string. Picking based on "Postgres vs MySQL vs NoSQL" alone misses most of what actually matters now.
Start with your data shape, not the brand name
- Genuinely unstructured or rapidly evolving data models — MongoDB Atlas remains the strongest fit when you don't want to design a rigid schema upfront, or your data shape changes frequently during early product iteration.
- You need resilience against entire region failures — CockroachDB is purpose-built to survive node, datacenter, and even full region outages without downtime, with a Postgres-compatible wire protocol.
What database branching actually changes
Neon and PlanetScale both bring Git-style branching to schema changes — create an isolated branch tied to a feature, test migrations against it safely, then merge with zero downtime. This replaces the old, riskier pattern of running untested migrations directly against shared staging or production.
- Neon — Branches Postgres, with true scale-to-zero — you pay nothing while a branch is idle. Excellent for preview environments tied to every pull request.
- PlanetScale — Branches MySQL, built on Vitess (the system that powers YouTube). Strong choice if your stack is already MySQL-based.
Why this matters in practice
Schema migrations are one of the most common causes of production incidents. Branching turns a risky, irreversible-feeling change into something you test exactly like a code change before it ever touches production data.
Do you need a database, or a full backend?
Supabase wraps managed Postgres with authentication, file storage, auto-generated APIs, edge functions, and realtime subscriptions — functioning as a complete backend rather than just a database. If you only need raw Postgres without those extra layers, a leaner managed Postgres (Neon, or a plain RDS-style instance) avoids paying for tooling you won't use.
- Choose Supabase if — You want auth, storage, and APIs without building and hosting them separately — common for solo founders and small teams shipping fast.
- Choose Neon if — You already have your own auth and API layer and just want fast, branchable, scale-to-zero Postgres underneath it.
