GNU Emacs

  • Performance can lag on very large files compared to newer editors.
  • Discoverability of features is poor without prior familiarity or external guides.

Logto

  • Advanced features like RBAC, organizations, MFA, and enterprise SSO are billed as separate paid add-ons rather than included in Pro.
  • Enterprise pricing is not published and requires contacting sales.
  • Token-based billing can make cost forecasting harder than flat per-MAU pricing for high-traffic apps.
