When to use PlanetScale

Choose if

You need MySQL with zero-downtime schema changes and horizontal sharding, and can handle the $39/month minimum.

Avoid if

You need a free tier, require foreign key constraints, or prefer PostgreSQL.

Vendor

PlanetScale Inc. Startup with $105M raised, pivoting business model after removing free tier in 2024. Built on Vitess (powers YouTube). Risk: business model uncertainty, community trust erosion from free tier removal.

Risk Flags

HIGH Free tier removed: PlanetScale removed its free tier in April 2024, forcing all free-tier users to migrate or pay. This caused significant community backlash and trust erosion. Many agents and blog posts still reference the free tier.
HIGH MySQL only: PlanetScale is MySQL-compatible (built on Vitess). If your stack uses PostgreSQL, PlanetScale is not an option. Most modern ORMs work fine but some PostgreSQL-specific features won't be available.
HIGH No foreign keys: PlanetScale (Vitess) does not support foreign key constraints. Referential integrity must be handled at the application level. This is by design for horizontal scaling but is a dealbreaker for some architectures.
MEDIUM Business model uncertainty: The free tier removal and business model pivot signal financial pressure. PlanetScale is well-funded but the trajectory is uncertain. Factor this into long-term decisions.

Pricing (Verified)

Tier	Price	Includes	Limits
Scaler	$39/month	10 GB storage; 1 billion row reads	1 production branch; 2 development branches
Scaler Pro	$99/month	10 GB storage; 3x more throughput	Horizontal sharding available
Enterprise	Custom	Dedicated resources	SLA; dedicated support; multi-region

Hidden Costs

Free tier removed in April 2024 — forced migrations caused community backlash
Row reads metered: overages at $1.50 per additional billion
Storage beyond plan: $2.50/GB/month
Branching is included, but branches consume storage quotas

    user=os.environ['PS_USER'],
    password=os.environ['PS_PASSWORD'],
    database=os.environ['PS_DATABASE'],
    ssl_ca='/etc/ssl/certs/ca-certificates.crt'
)
cursor = conn.cursor()
cursor.execute("SELECT * FROM users WHERE id = %s", (user_id,))

Compared To

vs	Choose PlanetScale when	Choose alternative when
Neon	You need MySQL and zero-downtime schema changes	You want PostgreSQL with a free tier
Supabase	You need MySQL-specific features or horizontal sharding	You want PostgreSQL with a full platform and free tier
AWS RDS	You want managed schema changes and database branching	You want full MySQL feature support including foreign keys

Verdict

Only choose PlanetScale if you specifically need MySQL with zero-downtime schema changes; otherwise pick a PostgreSQL option.

PlanetScale's zero-downtime schema changes and database branching are best-in-class for MySQL. The Vitess foundation is battle-tested (it powers YouTube). But the free tier removal, no foreign key support, and business model uncertainty make it harder to recommend. For MySQL, it's still the best managed option. For new projects without a MySQL requirement, PostgreSQL options (Neon, Supabase) are more flexible.

Best for: MySQL-native projects, apps needing zero-downtime schema changes, horizontal scaling

Avoid if: You want a free tier, need foreign keys, or prefer PostgreSQL
