A (somewhat) polished BetterAuth x Convex starter template with (decently) sane defaults

Hey ya'll, as part of my work for the Hackathon, I decided to take some of the effort I put into the Auth layer and factor it out into an easy to start with Template. Some things you get out of the box: - 🔑 Full auth flows (passphrase, magic links, email codes, resets), all wired to Convex with shared schemas so client + server don't drift. - 🌍 Social sign-in & linking (GitHub, Google, Apple) – just plug in envs and go. - 🛡️ Security helpers built in – zxcvbn passphrase strength meter, Have I Been Pwned plugin (Better Auth does have some neat plugins to say the least), email OTP. - 📦 Pre-styled UI using 9ui.dev primitives (think shadcn/ui but with Base UI + Tailwind v4 under the hood); can easily replace with shadcn/ui as they use the same CLI and I will probably improve the setup script to allow choosing between 9ui and shadcn/ui. - 🚦 Rate limiting & audit trails baked in – destructive ops log to Convex automatically. - 🕹️ A realtime counter example so you can check Convex queries/mutations are working. - 📬 Email preview in dev mode (no setup required – just sends them to console). - ⏰ Cron job - deletes temporary 24h username holds during verification. - 📖 Readme - An overly verbose readme that explains some decisions I made. - 🥚Easter eggs - Cause why not? - ⚙️ Solid DX: One command to setup everything. Happy to get some feedback, harsh criticism is always welcome as well. Hope you can get some use out of it. Here you go: https://github.com/Topfi/BetterAuth-Convex-9ui-shadcn-CLI-
