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.

Pusher

The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
Priority support with faster response times costs an additional $3,000/month on top of plan pricing.
