At our company we use better auth for every product that has any kind of user account logic. It’s great since it’s drop-in, the plugins give so much functionality that you’d have to roll on your own in so little time and the integrations with ORMs like drizzle and prisma mean that your schemas stay the SSOT that they should be, even for auth. It’s extensible where it needs to be and brings defaults that are more than sane. Also the RPC-like TypeScript client that you also get for free is so good I don’t know how I could live without that.
Glazing over, I just wanted to give props and say that whatever good happens to better-auth, it deserves it.
