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.

Pusher

  • The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
  • Priority support with faster response times costs an additional $3,000/month on top of plan pricing.
