  • Azure PostgreSQL is less compelling than dedicated PostgreSQL providers outside Azure ecosystem

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
