Convex Better Auth – Svelte Adapter

A lightweight Svelte/SvelteKit adapter for get-convex/better-auth.
It makes authentication idiomatic, type-safe, and SSR-ready in your Convex app.

Getting started

Option 1 — Ready-to-ship components (recommended)

Start with production-ready Auth and Organization components built on top of Convex Better Auth.
All source code is copied into your project (shadcn-style) — you own and control every line.

• Includes full sign-in, sign-up, profile, and organization flows
• Choose what you need: user management only, user + organization, or both
• Enable or disable features through simple toggles or by editing the code
• Fully editable and themeable through your design system
• Saves weeks of setup time while keeping complete flexibility

Option 2 — Build from scratch

Use the convex-better-auth-svelte adapter to design every flow and UI element yourself.
We recommend choosing this path only if you have highly specific requirements where even the modular components aren’t a good starting point —
for example, experimental onboarding flows or a custom multi-tenant model.

• Start from the raw hooks and helpers of convex-better-auth-svelte
• Wire up sign-in, sign-up, orgs, and sessions manually
• Best for projects with unique data models or unconventional UX
