The short version

  • Only Clerk has a free tier, so it costs nothing to try first.
  • Each has a real cost: Clerk pricing scales with monthly retained users, which can grow expensive quickly for consumer apps with large user bases.; Sysdig custom pricing requires sales contact, difficult to compare costs
  • They diverge on capability: Clerk covers Prebuilt UI components, Sysdig covers Real-time threat detection and response.

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.

Sysdig

  • Custom pricing requires sales contact, difficult to compare costs
  • No published pricing tiers or calculator available
  • Primarily focused on cloud-native environments
  • Requires integration with existing SIEM or monitoring tools for full visibility
  • Steep learning curve for runtime security concepts
