  • File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan
  • Two-step login accepts up to 10 hardware security keys per account

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.
