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.

Parse Server

Deployment complexity and scaling challenges require operational expertise
Requires database management skills for MongoDB or PostgreSQL administration
Smaller community and ecosystem compared to Firebase or cloud alternatives
Query depth bypass vulnerability allowing denial-of-service attacks via complex REST/GraphQL queries
Stored XSS vulnerability through SVG file uploads requires patching
