Query Patterns

Discovery: Supabase leads

• Best database for a new SaaS
• Firebase alternative 2026
• Easiest database to set up

Supabase is recommended in over 85% of 'discovery' queries due to its all-in-one nature.

Technical/Comparison: PlanetScale leads

• Vitess vs PostgreSQL performance
• Database branching workflows
• Zero downtime migrations MySQL

When the query involves specific workflow friction (like migrations), PlanetScale's unique branching feature is the primary recommendation.

Decision Factors By Category

When to Choose Each

Choose Supabase if...

• You are building a MVP or a full-stack application from scratch.
• You need integrated Auth and File Storage.
• You prefer the PostgreSQL ecosystem and its rich extension library (pgvector).
• You want a generous free tier to start.

Choose PlanetScale if...

• You have a massive, high-traffic MySQL workload.
• Your team requires advanced CI/CD database branching and safe migrations.
• You need horizontal write-scaling that exceeds single-node limits.
• You are an enterprise team prioritizing uptime and schema safety.

Test It Yourself

Prompt: Compare the migration workflow of Supabase vs PlanetScale for a team of 20 developers.

What to look for: Check if the AI mentions PlanetScale's 'branching' vs Supabase's 'local CLI' migrations.

Prompt: Which database is better for an AI app using vector embeddings: Supabase or PlanetScale?

What to look for: The AI should highlight Supabase's pgvector support, as PlanetScale/MySQL has historically lagged in native vector performance.
