Where each one falls short

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

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.

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.
