PlanetScale Overview

PlanetScale is a serverless MySQL platform built on Vitess, the same technology YouTube uses to manage its massive database infrastructure. The standout feature is database branching. You create a branch of your database, test schema changes against it, then merge when you're confident. No more sweating through production migrations.

I've looked into PlanetScale for projects where MySQL was a requirement. The developer experience is genuinely polished. The CLI is well-designed, the dashboard is clean, and the deploy request workflow for schema changes feels like git for your database. Non-blocking schema changes mean you never lock your tables during a migration.

The big downside is that PlanetScale killed their free tier. There is no Hobby plan anymore. The cheapest entry is now a single-node Postgres database at $5/mo, and the Vitess MySQL product they are best known for starts at $39/mo, which is a tough sell when Neon and Turso offer free Postgres and SQLite alternatives. And by default, PlanetScale disables foreign keys because Vitess doesn't handle them well. For solo developers who rely on database-level constraints to catch bugs, that's a real sacrifice.

CockroachDB Overview

CockroachDB is a distributed SQL database that's PostgreSQL-compatible. The pitch is compelling: your data is automatically replicated across multiple nodes and regions, you get strong consistency guarantees, and it handles automatic sharding without you touching anything. It's built for applications that absolutely cannot go down.

The serverless tier is free, which is nice. You get a Postgres-compatible database without paying anything to start. The SQL syntax is familiar if you know Postgres, and they've built tooling to make the setup straightforward.

But here's the reality check. CockroachDB is engineered for problems that solo developers almost never have. Multi-region replication, automatic failover, distributed transactions across geographic zones. These are enterprise concerns. If you're one person building a SaaS, you don't need a database that can survive a data center going offline. A single Postgres instance on Railway or Neon will serve you just fine for years.

Key Differences

Database philosophy is fundamentally different. PlanetScale optimizes for the developer workflow around schema changes and scaling MySQL. CockroachDB optimizes for distributed consistency and survival. Both solve scaling problems, but from completely different angles.

Foreign key support is a real issue with PlanetScale. Vitess doesn't handle foreign keys well, so PlanetScale disables them by default. CockroachDB supports foreign keys fully since it's Postgres-compatible. If database-level referential integrity matters to you (it should), CockroachDB has the edge here.

Pricing hits differently. PlanetScale has no free tier at all anymore, with a paid floor of $5/mo for single-node Postgres and $39/mo for the Vitess MySQL product. CockroachDB's Basic tier starts at $0/mo and includes 50 million Request Units plus 10 GiB of storage free every month, which is genuinely usable for small projects. For a solo developer watching costs, CockroachDB is cheaper to start with. The step up is CockroachDB's Standard tier at $0.18 per vCPU-hour, which adds up fast once you provision real compute around the clock.

SQL compatibility matters. PlanetScale is MySQL. CockroachDB is Postgres-compatible. Most modern ORMs and frameworks default to Postgres these days. If you're using Prisma, Drizzle, Django, or Rails, Postgres compatibility means less friction.

Developer experience favors PlanetScale. The branching workflow, the deploy requests, the clean dashboard. PlanetScale nailed the DX. CockroachDB's tooling is fine, but it's built for infrastructure teams, not solo developers. The complexity leaks through.

By the Numbers (2026)

Checked on 2026-05-29.

PlanetScale

Cheapest paid entry is a single-node Postgres database from $5/mo, with Vitess MySQL plans starting at $39/mo and Metal (local NVMe) from $50/mo on the published pricing page. There is no free tier; the old Hobby plan was removed.
The MySQL side runs on Vitess, whose latest release is v24.0.1 (published 2026-05-07). Vitess is open source under Apache 2.0 and sits at 20,976 GitHub stars and 2,343 forks.
PlanetScale also offers managed Postgres running on PostgreSQL 17 and 18, with Postgres 18 now available on the platform.
The official serverless driver, @planetscale/database, is at version 1.20.1 and pulled 187,805 downloads in the week of 2026-05-21 to 2026-05-27 on npm.

CockroachDB

The Basic tier starts at $0/mo and includes 50 million Request Units and 10 GiB of storage free each month (Cockroach Labs values that allowance at $15/mo).
Beyond the free allowance, Basic bills $0.20 per additional million Request Units and $0.50 per additional GiB-month of storage.
The Standard tier starts at $0.18 per vCPU-hour (2 vCPUs minimum, up to 200 vCPUs and 3 TiB), and Advanced starts at $0.60 per vCPU-hour with unlimited scaling. New organizations can start with $400 in credits and no credit card on Basic and Standard.
The latest GA release is CockroachDB v26.2, dated 2026-04-27. The cockroach repository is open source and sits at 32,170 GitHub stars and 4,131 forks.

Real Cost at Solo-Dev Scale

Numbers below use the per-unit rates above, checked on 2026-05-29. The goal is a realistic side-by-side, not a benchmark.

Assume a typical solo SaaS in its first year: a small Postgres-shaped workload, roughly 8 GiB of data, light-to-moderate query traffic, single region. On CockroachDB that workload maps to Request Units and storage on the Basic tier.

CockroachDB Basic at this scale. Storage of 8 GiB sits under the 10 GiB free allowance, so storage is $0. The free tier also covers 50 million Request Units per month. A low-traffic app that stays inside both ceilings pays $0/mo. If the app grows to, say, 80 million Request Units in a busy month, only the 30 million over the free 50 million bill, at $0.20 per million, which is $6/mo. Storage climbing to 25 GiB adds 15 GiB over the free 10 GiB at $0.50 each, another $7.50/mo. So a meaningfully busier month still lands near $13.50/mo on Basic.

PlanetScale at this scale. There is no free option. The floor is a single-node Postgres database at $5/mo, or $39/mo if you specifically need the Vitess MySQL product with its branching workflow, or $50/mo for Metal. So month one is $5 to $50 depending on which product you pick, against CockroachDB's $0.

The honest read: at genuinely small scale, CockroachDB Basic is cheaper because $0 beats $5. PlanetScale only justifies its floor once you are actually using the branching and zero-downtime-migration workflow that the price buys. Neither pricing model punishes a solo dev badly, but only one of them lets you start at nothing.

When to Choose PlanetScale

You're committed to MySQL and need zero-downtime migrations
Schema changes are frequent and risky in your workflow
You can budget at least $5/mo for Postgres, or $39/mo for the Vitess MySQL product
You don't need foreign key constraints
You value developer experience over raw features

When to Choose CockroachDB

You need Postgres compatibility without managing Postgres yourself
You want a free tier to start experimenting
Multi-region data distribution is a real requirement (not a theoretical one)
Your application demands strong consistency across distributed nodes
You're building something that genuinely needs to scale globally

The Verdict

Neither of these is the right choice for most solo developers. That's the honest answer. PlanetScale has no free tier, with a $5/mo Postgres floor and $39/mo for the MySQL product without foreign keys. CockroachDB's Basic free tier is fine but you're carrying complexity you don't need.

If you're forced to choose between these two, CockroachDB's free tier and Postgres compatibility make it the more practical starting point. But my actual recommendation? Skip both. Use Neon for free serverless Postgres or Supabase for a full backend-as-a-service. You'll get a better experience, better pricing, and features that actually matter at solo developer scale. Save distributed databases for when you actually have distributed problems.
