What makes it different?

Focus on your product, not setup

Everything you need to launch your SaaS in no time.

Build for web, mobile, and browser extension simultaneously with a unified codebase.

export const billingRouter = new Hono()
  .post(
    "/checkout",
    validate(
      "json",
      z.object({ plan: z.object({ id: z.string() }) }),
    ),
    enforceAuth,
    async (c) => {
      logger.time("checkout");
      const result = await checkout({
        user: c.var.user,
        ...c.req.valid("json"),
      });

      await db.insert(orders).values({
        externalId: result.id,
        userId: c.var.user.id,
      });

      await sendEmail({
        template: EmailTemplate.INVOICE,
        to: c.var.user.email,
        variables: { user: c.var.user, ...result },
      });

      track("checkout.created", {
        userId: c.var.user.id,
        checkoutId: result.id,
      });

      logger.timeEnd("checkout");
      return c.json(result);
    },
  ).post("/webhook", (c) => webhookHandler(c.req.raw));

Ship Better Auth in production, not a tutorial

Most Next.js Better Auth guides stop at login. TurboStarter ships Better Auth wired to organizations, billing webhooks, admin tooling, and a shared API — so you are not rebuilding session handling every time you add a paid feature.

If you are evaluating a Better Auth starter or Next.js Better Auth boilerplate, the real cost is not the library — it is MFA, passkeys, invite flows, plan-gated routes, and keeping mobile and web in sync.

TurboStarter Core includes Better Auth with MFA, passkeys, OAuth, and magic links — one lifetime license, full source code, no monthly template fee.


What Better Auth looks like in TurboStarter

TurboStarter uses Better Auth as the auth layer across web, mobile, and browser extension — one session model, one permissions system.

Why teams pick Better Auth over legacy stacks

  • Type-safe end to end — schema, server, and client share generated types
  • Plugin architecture — add 2FA, organizations, or admin without forking
  • No vendor lock-in — self-hosted sessions on your Postgres database
  • Edge-friendly — works on serverless without a separate auth service bill

better-auth's plugin system lets you add features incrementally without bloating your bundle.


Better Auth + the rest of your SaaS stack

Auth alone does not launch a product. TurboStarter pairs Better Auth with the infrastructure every SaaS needs on day one:

LayerWhat you get
DatabaseDrizzle ORM on Postgres with migrations and type-safe queries
APIHono routes with auth-aware middleware and React Query
BillingStripe, Lemon Squeezy, Polar, or Dodo with working webhooks
TeamsOrganizations, invites, and RBAC
ClientsNext.js web, Expo mobile, and WXT browser extension

Read the API overview, database overview, and billing docs to see how auth connects to the rest of the stack.


TurboStarter vs LaunchSaaS for Better Auth

LaunchSaaS is a strong web-only starter. The gap shows up when you want Better Auth without Supabase Auth lock-in or a path to mobile and extension clients.
