Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Clerk

  • Pricing scales with monthly retained users, which can grow expensive quickly for consumer apps with large user bases.
  • Enterprise SSO connections beyond the first are billed as add-ons, adding cost for larger organizations.
  • The Business tier's extra dashboard seats cost $20/month each, which adds up for larger teams.
  • Enterprise-tier features like the 99.99% uptime SLA require annual contracts rather than flexible monthly billing.

Liveblocks

  • On the Free plan, each metered feature has a hard cap and simply pauses when exceeded rather than allowing overage.
  • The jump from Pro ($30/month) to Team (starting at $600/month) is steep for teams that outgrow Pro but don't need full Team scale.
  • Multi-region hosting and SCIM provisioning are Enterprise-only and require custom pricing.
