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.

Turbopack

  • Effectively coupled to Next.js; using it standalone is not the supported path
  • Younger than the alternatives, and ecosystem plugin support is narrower than webpack’s
  • Benchmark claims have been contested publicly, so measure on your own project rather than trusting headline numbers
  • Being Vercel-driven ties its roadmap to one company’s framework priorities
