The short version

  • Only CouchDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: CouchDB append-only storage model may have performance implications for certain workloads with high update rates; PlanetScale eBS High Availability requires 3-node configuration with replication overhead
  • They diverge on capability: CouchDB covers Multi-master Replication, PlanetScale covers Database Branching.

What people use each for

The jobs each tool is most often brought in to do.

CouchDB

  • Offline-first applications requiring seamless replication across mobile and server environmentsnot PlanetScale
  • Multi-master deployments where data consistency eventually resolves across regionsnot PlanetScale
  • IoT and edge computing scenarios with intermittent connectivitynot PlanetScale

PlanetScale

  • MySQL database hosting with automatic failover and replicationnot CouchDB
  • Vitess-based sharding for horizontal scaling across large datasetsnot CouchDB
  • Cloud provider flexibility across AWS, GCP, Azure with 60+ regionsnot CouchDB
  • Cost-effective database clusters using ARM64 architecture optionsnot CouchDB

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CouchDB

  • Append-only storage model may have performance implications for certain workloads with high update rates
  • Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
  • No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases

PlanetScale

  • EBS High Availability requires 3-node configuration with replication overhead
  • EBS Non-HA single-node option lacks redundancy and automatic failover
  • Pricing varies by cloud provider and region, requiring queries for specific rates
  • ARM64 architecture only available on EBS tier, not Metal deployments
