PlanetScale - Pros & Cons

Pros

  • Supports both Vitess and Postgres, giving teams options across a horizontally scalable MySQL-compatible architecture and a widely adopted relational database engine.
  • Vitess offering is specifically positioned for ultra scalability through horizontal sharding, which is valuable for applications that may outgrow a single-node database model.
  • Website highlights Metal databases with locally attached NVMe drives, making performance a central part of the platform rather than a secondary feature.
  • Deployment options include PlanetScale Managed with bring-your-own-cloud, which can help organizations with stricter security, compliance, or infrastructure ownership requirements.
  • Database Traffic Control is presented as a way to apply resource budgets to Postgres query traffic, addressing operational risk from expensive or noisy workloads.
  • Positioning is focused on production cloud databases rather than generic developer convenience, making it suitable for teams that care deeply about database reliability and scale.

Cons

  • PlanetScale no longer offers a free Developer or Hobby plan, so even small projects need to start on a paid Base plan.
  • PlanetScale appears database-focused, so teams looking for a full backend platform with built-in auth, storage, and application services may need additional tools.
  • Vitess and horizontal sharding can introduce architectural complexity for teams that are used to simple single-instance relational databases.
  • Bring-your-own-cloud and managed deployment options may be better suited to mature teams than small projects that want the simplest possible setup.
  • Feature availability differs by engine, with Data Branching listed for Vitess and Database Traffic Control listed for Postgres, so teams need to validate that their preferred engine supports the exact workflow they want.

Supabase - Pros & Cons

Pros

  • Postgres foundation is portable and familiar
  • free plan is generous for prototypes with 50,000 MAUs
  • pricing page exposes real overage numbers for MAUs, disk, egress and storage
