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.

Sketch

  • macOS-only for editing, blocking Windows and Linux users from accessing design features
  • Real-time collaboration feels less seamless than Figma with occasional sync delays
  • Limited built-in image editing capabilities, requiring external software for bitmap work
  • Subscription required for cloud features and collaboration, losing access if subscription lapses
