  • Enterprise-grade SSO and governance are locked behind the Scale-Up and Enterprise tiers.
  • Self-hosting requires operating and updating the platform yourself, unlike a fully managed SaaS competitor.

Healthchecks

  • Free tier limited to 20 jobs, restricting scale for small teams

  • No workflow orchestration or job scheduling capabilities
  • SMS and phone credits consumed separately on paid plans
