Does PlanetScale Work With Strapi?
PlanetScale and Strapi work together seamlessly—Strapi's Node.js database layer supports MySQL connections, and PlanetScale is MySQL-compatible with excellent driver support.
Quick Facts
How PlanetScale Works With Strapi
PlanetScale integrates with Strapi through standard MySQL drivers (mysql2 for Node.js), requiring only connection string configuration in Strapi's database settings. PlanetScale's MySQL 8.0 compatibility means Strapi treats it as a regular MySQL database—no special adapters needed. The real advantage is PlanetScale's serverless scaling and branching workflow: developers get instant database branches for testing schema migrations before merging to production, which pairs perfectly with Strapi's content management workflows. Connection pooling via PlanetScale's Serverless driver is essential for production since Strapi spawns many concurrent connections; without it, you'll hit connection limits quickly. The architecture works elegantly: Strapi's ORM (Knex.js under the hood) executes queries against PlanetScale's endpoints, and the MySQL protocol is fully supported with no dialect conflicts.
Best Use Cases
PlanetScale Connection in Strapi (v4)
npm install mysql2// config/database.js
module.exports = ({
connection: {
client: 'mysql',
connection: {
host: process.env.DATABASE_HOST || 'localhost',
port: parseInt(process.env.DATABASE_PORT) || 3306,
database: process.env.DATABASE_NAME || 'strapi',
user: process.env.DATABASE_USER || 'root',
password: process.env.DATABASE_PASSWORD || '',
ssl: { rejectUnauthorized: false }, // Required for PlanetScale
},
pool: { min: 2, max: 10 }, // Connection pooling
acquireConnectionTimeout: 10000,
},
});
// .env.local

Connection pooling exhaustion causes 'too many connections' errors under load
Fix: Use PlanetScale's Serverless Driver (mysql2/promises) or configure connection pool limits in Strapi config: database.connection.pool = { min: 2, max: 10 }
Foreign key constraints disabled by default on PlanetScale (safe migrations), but Strapi expects them for relation integrity
Fix: Enable foreign keys in PlanetScale dashboard settings, or ensure Strapi's content-type relations are properly defined to handle eventual consistency
Strapi's auto-migration feature may fail if PlanetScale is in safe mode blocking DDL on production branches
Fix: Use PlanetScale's branching workflow: test migrations on dev branches, promote schema via deploy requests, then run Strapi on the updated production branch
Slow initial connection handshake adds latency to serverless function cold starts
Fix: Use connection pooling and consider Strapi self-hosted or containerized for consistent connection reuse
Alternatives
- •Supabase (PostgreSQL) + Strapi — better for complex relational queries but requires pg driver
- •MongoDB Atlas + Strapi — document-based, excellent for unstructured content but different transaction model
- •AWS RDS MySQL + Strapi — fully managed traditional database, more expensive but enterprise-grade support
