Recently I wanted to add auth to my pet project, and between (a) using better-auth, then integrating 3rd party mailer service, and rolling out my main dashboard (b) leeching off free tier of Auth0 or Clerk and getting all batteries included I've chose the latter.
The fact that better-auth doesn't come with barebone dashboard is criminal.
For pet project it doesn't matter if I have to integrate Resend or Clerk, it's still some mental overhead I have to account for, but with Clerk at least I don't have to manage my users using sql queries.
People say it's better because you can embed it in your app. I don't buy that either. If I'd have to rollout better-auth I'd do that as a separate app, just to encapsulate database, dashboard, and integrations.
Anyway, glad it's getting traction, I just don't get all the hype around it.
