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

PartyKit

  • Documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms
  • Commercial free tier requires deploying to the user's own Cloudflare account, adding setup complexity
  • Storage on the free Individual plan clears every 24 hours, limiting it to prototyping rather than persistent production data
  • Smaller ecosystem and community than more established realtime infrastructure providers
