Clerk manages auth.
Pubflow manages trust.
TL;DR
- Use Clerk if you just need raw authentication features for external infrastructure.
- Use Pubflow for a completely integrated backend where auth is native to the whole environment.

Why Pubflow Wins
Complete backend included
Pubflow provides the entire heavy lifting logic you need, tightly integrated.
Trust-first architecture
Unlike just hosting scripts, Pubflow manages the full context flow securely from edge to database row.
No missing pieces
Auth, compute, databases, and configuration—all unified under one platform.
Problems with Clerk
Only solves one thing
You still need a database. You still need an API. You still need compute environments.
Fragmented context
Stitching a third party auth to a third party DB to a third party handler is complex and brittle.
