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.

Rapid7 InsightVM

  • InsightVM is now sold inside Exposure Command rather than as a standalone product
  • Rapid7 states pricing is not publicly listed and is provided by custom quote based on the customer's environment
  • Billing counts billable assets including devices, software, identities, cloud compute instances and applications, so the asset count grows faster than a device inventory suggests
  • Cloud security, compliance, infrastructure as code scanning and application security testing require the Ultimate package rather than Essentials
  • Volume discounts are described as commonly available for larger asset counts, so smaller buyers pay the higher unit rate
