Why developers leave PlanetScale: 2024 free tier removal made minimum $39/mo barrier painful for indies, no foreign-key constraints (Vitess limitation) constrains some data models, and MySQL-only means no Postgres ecosystem access. Teams pushed by these limits evaluate Postgres alternatives.
Neon is the Postgres alternative — foreign keys, full SQL, pgvector, scale-to-zero economics. For new projects in 2026 most reviewers chose Postgres options over MySQL. Migration off Vitess to Postgres is non-trivial but feasible.
Supabase bundles Postgres + Auth + Storage + Realtime. For teams whose PlanetScale choice was primarily database, with auth/storage solved separately, Supabase's bundling can save vendor sprawl.
MongoDB Atlas for teams whose data shape was actually document-oriented. The schema-flexibility might fit better than forcing MySQL relational. Wrong alternative for relational data.
Most reviewers report 2-4 sprints. SQL-flavor differences (MySQL → Postgres) require schema rewriting. Application code that uses MySQL-specific features needs updates. Plan for a sprint per major service. Migration tools like pgloader help with the data move.
For teams already on PlanetScale at scale: yes, the schema-change deploy-request workflow remains the moat. For new projects in 2026 most reviewers picked Postgres options. The bifurcation is by data-model preference and existing ecosystem.
Both are serious distributed-SQL options for teams whose PlanetScale choice was about scale. We rank them in our distributed-database evaluations. For teams not requiring multi-region active-active SQL, single-region managed Postgres is simpler.
