I have built seven production apps on Supabase. I have evaluated PlanetScale and Neon for forks | here is the honest trade space for B2B SaaS MVPs in 2026.
Supabase (My Default)
Wins: Auth + Postgres + RLS in one product, great Next.js DX, realtime when needed. Pain: RLS complexity for new devs, edge function cold starts, connection pooling discipline required at scale.
PlanetScale
Wins: branching workflows for schema changes, MySQL scale story. Makes sense if your team is MySQL-native and you bring your own auth. You lose Postgres RLS | tenant isolation moves to application layer.
Neon
Wins: Serverless Postgres, scale-to-zero cost profile. Good with external auth (Clerk, Auth.js). You assemble more pieces than Supabase ships in one box.
Decision Matrix
- Need RLS + Auth fast → Supabase
- MySQL + branch-based migrations → PlanetScale
- Postgres only, bring own auth → Neon
Need this shipped in production, not just in a blog post? Start your MVP.
