Pros and cons
What PlanetScale does especially well — and the limits to anticipate.
Pros
- Unique schema branching to test database changes risk-free
- Automatic scalability with no server management
- MySQL-compatible, relatively simple migration from an existing database
Cons
- Branching model requires a specific learning curve
- More expensive than managing your own MySQL on a classic server
- No native foreign key support, a constraint to be aware of
PlanetScale: when it makes sense.
Worth it once schema migrations become a real risk for your team.
Keep if
You want to avoid risky production database migrations. You're already on MySQL and want scalability with no server management
Challenge if
You need native foreign keys — that's a real limitation of the tool. Managing your own MySQL is enough and cheaper for your volume
