The short version

  • Each has a real cost: PartyKit documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.; Railway plan fees are usage credits rather than allowances, so the $5 Hobby and $20 Pro fees are spent on compute and anything beyond is billed on top
  • They diverge on capability: PartyKit covers Stateful edge servers, Railway covers Git integration.
  • Prices and features above were last checked on 30 August 2026.

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.

Railway

  • Plan fees are usage credits rather than allowances, so the $5 Hobby and $20 Pro fees are spent on compute and anything beyond is billed on top
  • The free plan carries $1 of monthly credit and caps a service at 1 vCPU and 0.5 GB
  • Compute is metered per second for both memory and CPU, so cost tracks uptime rather than traffic and an idle service still bills
  • Egress is $0.05 per GB on top of compute
  • The Pro fee is per workspace rather than per user or per project
