🚀 How do you want to start?

🧪 1) Custom implementation

When to choose this: You have a very specific opinion about how authentication should work — maybe a custom onboarding flow, invitation logic, or multi-tenant setup that doesn’t fit typical patterns.

• You’ll wire up sign-in, sign-up, orgs, and sessions yourself.
• Perfect if you enjoy designing every flow from scratch.
• Expect days → weeks/months of work depending on polish.

⚡ 2) Prebuilt components (shadcn-style)

Recommended for 99 % of projects.
Start with fully-featured Auth & Organization components that you own outright — all source code is copied into your project.

• Polished UX and responsive layouts built for production
• 100 % editable, themeable, and extendable
• No vendor lock-in: everything runs on your Convex instance
• Saves weeks or months of engineering time
• Still gives you the same control as building it yourself — just faster
