PartyKit

  • 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.

Vercel

  • Usage-based pricing can spike unexpectedly during traffic surges or DDoS attacks
  • No spending limit controls or automatic shutoff mechanisms
  • Bandwidth costs ($0.15/GB) quickly accumulate for high-traffic applications
