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.

Orb

  • Custom pricing model requires sales consultation, no transparent public pricing
  • Pricing based on both events and billing volume adds complexity to cost estimation
  • Enterprise-focused positioning may be overkill for simple subscription use cases
  • Requires integration with existing accounting systems for full value
  • Limited information on free tier or trial availability
