The Better Auth SaaS starter kit for Next.js, with organizations, roles, and billing wired in

Better Auth runs inside your app and stores users, sessions, and organizations in your database. Organizations, invitations, custom roles, MFA, passkeys, magic links, and OAuth, tied to Stripe or Polar.

Authentication

Sign-in your users already expect

Password, magic link, passkeys, OAuth and multi-factor authentication, with the emails that go with them.

Multi-factor authentication

Users enroll an authenticator app and are challenged for a code at sign-in.

Transactional emails

Templates written in JSX with React Email, sent through Resend or Nodemailer (SMTP).

Every sign-in method

Password, magic link and social sign-in, configured per environment.

Passkeys

Opt-in sign-in with Face ID, Touch ID, Windows Hello or a security key. No password to phish.

Magic links

Passwordless sign-in: users get a one-time link by email instead of typing a password.

Accounts and billing

Everything a multi-tenant B2B SaaS needs

The multi-tenant SaaS boilerplate parts: auth, billing, teams with roles, and a super admin that can impersonate or ban users and teams, plus the screens your customers use to manage them.

Roles and permissions

Roles map to permissions that your code and your database policies both check.

Customer portal

Users change plans, update payment methods and download invoices without a support ticket.

Team accounts

Users belong to several teams and switch between them, or work in their personal account.

Billing webhooks

Flat, per-seat and metered subscriptions through Stripe Checkout, with webhooks that keep plans and seats in sync with your database.

Swappable providers

Billing, email, CMS and monitoring sit behind interfaces, so changing provider is configuration, not a rewrite.

Internationalization

Every UI string comes from translation files, so adding a language is content work.

Built for coding agents

Guardrails your agent works inside

Rules, an MCP server, skills and strict checks keep generated code in the kit’s patterns.

Agent rules

AGENTS.md files at the root and in each package teach coding agents the kit’s conventions.

Strict code standards

Strict TypeScript and linting across the monorepo, so type errors surface before your users find them.

MCP server

Gives Claude Code, Cursor, Codex and Gemini structured access to the kit: database, components, translations, checks and PRDs.

E2E tests with Playwright

Tests for authentication, team accounts and invitations, written with page objects you can extend.

You own the code

The full source lives in your repository. Nothing is hidden behind a package you cannot edit.

Agent skills

Skills in every Better Auth kit: /reviewer reviews the diff, /bug-hunt sweeps the codebase, and /drizzle-expert or /prisma-expert handles schemas and queries.

From clone to product code in one session

A production-ready Better Auth SaaS Starter Kit

The setup, stack, and tooling are decided, so your first commit is a product feature.

Quick Setup

Clone the repository, install dependencies, and start the dev server: the full SaaS runs locally, not a demo shell.

Modern Tech Stack

Email/Password

Secure email/password authentication with built-in password reset, email verification, and account recovery flows.

Magic Link

Passwordless sign-in: users click a link in their inbox and skip the password entirely.

Passkey

WebAuthn passkeys: users sign in with Face ID, Touch ID, Windows Hello, or a hardware security key. Phishing-resistant, with nothing to reset.

Social Sign-in

Google, GitHub, Facebook, X, Discord, and many more OAuth providers ready to configure.

Multi-Factor Authentication

TOTP-based MFA to protect your users' accounts, with enrollment and challenge screens included.

My favorite so far is @gc_psk and @makerkit_dev ship cursor rules along with updates to the framework. That's been really useful to pull in new version (via git remote) and things stay in sync.
RYRyan Hayeson X
Just started using MakerKit and it's a total game-changer. 🚀 Wish I had this when I was building Phishr. Instant team management and billing? Insane.

Second that! Giancarlo provides amazing support!! 😄
ANAndrew Willshire@acwillshire
You need to check @makerkit_dev by @gc_psk — it’s the best I’ve seen so far. It’s feature complete, plenty examples, amazing docs, great Discord community, the dude provides support even days after his weeding (which is crazy!) I’m not affiliated in every way, just a happy cx.
IVIvor@madebyivor
Honestly @makerkit_dev is great. More for B2B products but really clean and well documented.
KIKiara Bickers@kiarabickers
Amazing! @gc_psk has built a masterpiece with this one!
ADAditya TripathiClimactic · @AdityaTripathiD
I just stumbled upon @makerkit_dev (and you!), it's impressive, I thought it was a big team behind how many features I saw (and I've been working in software a long time!) I was just looking for a free boilerplate, but the lifetime licence makes it a no brainer. Thank you!
SÉSéraphin Hochart@nsphin
I would have totally agreed with you until… I found @makerkit_dev last year. This is by far, the best boilerplate I found those past years. The dev is pushing new features and updates almost every week. His documentation (specially migrating to Next 15) is the best I’ve seen.
DADavid Dias@TheDavidDias
Makerkit is a gem for makers, if I was not building a desktop app I would be using it for sure, maybe for my next project
KHKhalil NajjarCohere AI · @knajjars
I landed on MakerKit after getting into boilerplates with ShipFast. Much better.
WIWill Mitchell@StartupBros
1000% recommend buying a good boilerplate (or making your own) I use @makerkit_dev it's so good I had an affiliate link, but I can't find it at the moment
DADan Schoonmaker@DanSchoonmaker
For anyone who wants to build their own SaaS, I recommend trying out @makerkit_dev. Thanks to @gc_psk for creating such a fantastic tool that makes building websites a breeze! #SaaS #buildinpublic
CACarl Chan@CarlChan77
We loved the product since when Giancarlo released the first version, and are building upon it ever since for all of our products. Highly recommended for all indie makers out there.

Better Auth is a library, not a SaaS

Adding Better Auth to an app is the quick part. Wiring its organizations to roles, invitations, per-seat billing, and an admin panel takes longer. With AI coding tools, that is still 49-81 hours of senior developer time, including fixing the patterns AI got wrong.

In short

A Better Auth SaaS boilerplate: self-hosted authentication, with the SaaS already built around it

Better Auth handles identity. MakerKit adds the organizations, roles, billing, and admin that turn it into a product.

What is the MakerKit Better Auth SaaS Starter Kit?

The MakerKit Better Auth SaaS Starter Kit is the Drizzle or Prisma edition of MakerKit, available for Next.js 16 and TanStack Start. Better Auth runs inside your app and stores users, sessions, and organizations in your own Postgres. The kit adds organizations with invitations and custom roles, passkeys, MFA, Stripe or Polar billing, and a super admin with impersonation.

Auth in your database

Users, sessions, and organizations live in your Postgres. No external auth service and no per-user pricing.

Organizations and custom roles

Better Auth's organization plugin with invitations, plus roles each organization defines from the UI.

Every sign-in method

Email and password, magic links, passkeys, OAuth, and TOTP MFA, with rate limiting and captcha plugins.

Stripe or Polar billing

Per-organization subscriptions with per-seat enforcement and metered usage.

Two frameworks, two ORMs

Next.js 16 or TanStack Start, with Drizzle or Prisma 7. Same features in every combination.

Built for AI coding agents

AGENTS.md and CLAUDE.md files at the root and in each package, rules for Claude Code, Cursor, Codex, and Gemini, and an MCP server your agent can call.

Best for

  • Teams that want users and sessions in their own database, with no per-user auth pricing
  • B2B SaaS that needs organizations and custom roles per customer
  • Developers who prefer Drizzle or Prisma on any Postgres host over a managed backend

Not for

  • Teams that want a vendor-hosted auth dashboard and prebuilt user management
  • Projects already committed to Supabase Auth and RLS; the Supabase kit fits better
  • Anyone who does not want to own auth security settings in production

With and without MakerKit

Without MakerKit: Hosted auth that bills per active user

With MakerKit: Self-hosted Better Auth with no per-user fees

Without MakerKit: Better Auth installed, organizations still unwired to billing

With MakerKit: Organizations connected to roles, invitations, seats, and admin

Without MakerKit: Your user table held by a vendor

With MakerKit: Your user table in your own Postgres

Without MakerKit: Roles hardcoded for every customer

With MakerKit: Custom roles each organization manages

Questions before you buy

Better Auth SaaS Starter Kit FAQ

Not covered here? Ask in Discord or contact me.

What is the Better Auth SaaS Starter Kit?

It is MakerKit's Drizzle and Prisma kits, which use Better Auth for authentication. Each is available for Next.js 16 and TanStack Start and ships email and password, magic links, passkeys, OAuth, TOTP MFA, organizations with invitations and roles, a super admin with user impersonation, and Stripe or Polar billing.

Why use Better Auth instead of Clerk or Auth0?

Ownership and cost. Better Auth runs inside your app and stores users, sessions, and organizations in your own Postgres, so there is no per-user auth pricing and no third party holding your user table. The trade-off is that you operate auth yourself: secrets, email verification, and rate limiting are configured by the kit, and keeping them on in production is your job.

How do organizations and roles work with Better Auth?

The kit configures Better Auth's organization plugin for teams, members, and invitations, and adds custom roles that each organization can define from the UI without code changes. Your code checks access through the kit's permissions API and custom authorization policies.

Drizzle or Prisma: which Better Auth kit should I buy?

Drizzle if you like queries that read like SQL and no generated client. Prisma 7 if your team already knows Prisma's schema language and client. Auth, organizations, billing, and admin are the same in both, and each is its own license, so pick the ORM you want to live with.

Can users sign up without creating an organization?

Yes. Account modes let you run personal accounts only (B2C), organizations only (B2B), or both (B2B2C), chosen in configuration.

Which databases and hosts does it support?

PostgreSQL from any provider: Neon, Supabase Postgres, Railway, or your own server. The deployment docs cover Docker and Railway, and because Better Auth runs in-process there is no separate auth service to deploy.

Is MakerKit a one-time purchase or a subscription?

A one-time purchase. You get a lifetime license to the source code, continuous updates for the stack you bought, and unlimited projects for your own business, with no renewal fee. Building products for clients requires a Team license, and each client that receives the code needs their own license.

What support is included?

Discord support from me, Giancarlo, the founder who works on MakerKit full-time, and from the community. I help with setup, kit-related issues, and questions about the codebase. Team licenses add a private Discord channel for your team.

Own your auth. Skip the plumbing around it.

Better Auth, organizations, custom roles, and billing, already connected in your own Postgres. Pick Drizzle or Prisma above and start on the product instead of the auth wiring.
