Clerk wins on UI polish and org features but has real lock-in and per-user pricing that scales poorly. Supabase Auth is the natural choice when already using Supabase, especially for row-level security integration. Better Auth, an open-source TypeScript library, has matured enough to be the new default for margin-sensitive or flexibility-focused projects. The post covers switching costs, lock-in math, and a decision framework based on UI sensitivity, stack, and cost profile. Auth0, Firebase Auth, NextAuth, and WorkOS are briefly dismissed for most solo dev use cases. ## Full article daily.dev links to this article rather than hosting it.
