# ixartz/SaaS-Boilerplate: a Next.js starter with Clerk auth and multi-tenancy

> A free, MIT-licensed Next.js and Tailwind CSS starter that ships authentication, organizations, roles and a Drizzle database layer. It is a good fit if you accept Clerk and Postgres as your starting assumptions, and a poor one if you want to own the auth layer or run on a serverless-only stack.

**ixartz/SaaS-Boilerplate** — 🚀🎉📚 SaaS Boilerplate built with Next.js + Tailwind CSS + Shadcn UI + TypeScript. ⚡️ Full-stack React application with Auth, Multi-tenancy, Roles & Permissions, i18n, Landing Page, DB, Logging, Testing

## The week of setup work this template removes

Every multi-tenant SaaS starts with the same unglamorous list: a sign-up flow, a session, an organization concept, a way to invite a colleague, a role check on the server, a dashboard shell, and a database migration pipeline. None of it is the product, and all of it has to exist before the product can be demoed to anyone.

This project is a Next.js App Router application that already contains that list. The README describes it as a template with built-in authentication, multi-tenancy with team support, roles and permissions, a database layer, i18n, a landing page, a user dashboard, form handling, logging, error reporting through Sentry, testing, and user impersonation. The intended reader is a small team or a solo developer who wants to start from a working tenant model instead of assembling one.

The trade-off is stated plainly by the dependency list rather than by the README: authentication is Clerk, and organizations are Clerk organizations. You are not adopting a generic auth abstraction. You are adopting a specific vendor's data model and building on top of it.

## How the pieces fit: Clerk for identity, Drizzle for everything else

The architecture splits cleanly in two. Identity, sessions, and organization membership live in Clerk. Application data lives in your own database, reached through Drizzle ORM. The README notes that Drizzle works across PostgreSQL, SQLite and MySQL, and recommends Neon as a hosted PostgreSQL option that has been tested with the template.

The repository root shows the shape of that split. There is a migrations/ directory for Drizzle migrations, a drizzle.config.ts for the connection and schema location, and a src/ directory holding the application. The package.json scripts reveal a detail worth knowing before you clone: development does not require a running database server. The dev script runs db-server:file, which starts pglite-server against a local.db file and runs the migrations, in parallel with next dev. A build-local script does the same thing in memory. Production is different: the build script runs db:migrate and then next build, so migrations are applied as part of the build step, not by a separate process.

That choice has consequences. Migrations running inside the build means a failed migration fails the deploy, which is usually what you want, but it also means the build environment needs database credentials and network access to the database. The README does not document a rollback path for a migration that has already been applied.

## Installing it and getting a tenant-aware page running

The package.json engines field requires Node 24 or later, so check that before anything else. The README points to the live demo at react-saas.com for a working authentication and multi-tenancy example, and the repository carries both .env and .env.production at the root as the starting point for configuration.

Once dependencies are installed, the development command starts the local PGlite database, applies migrations, and launches Next.js together. The README does not spell this out, but the script names make it clear:

```bash
npm install
npm run dev
```

You should end up with a local.db file in the project root, the migrations applied, and the Next.js dev server serving the landing page. The separate scripts exist if you want to run the pieces apart: dev:next for the app alone, and db-server:memory for an in-memory database that discards itself when the process ends.

Schema changes go through Drizzle Kit rather than hand-written SQL. After editing the schema, generate a migration and apply it:

```bash
docker run --rm -it -p 5432:5432 -e POSTGRES_PASSWORD=password postgres:17
npm run db:generate
npm run db:migrate
```

A Postgres container is the practical way to test against the database you will actually deploy on, since PGlite is a development convenience rather than a production target. The README does not list a Docker command, so treat the container line as your own choice of local Postgres, not a documented step. To inspect what is in the database, db:studio opens Drizzle Studio.

The test and quality scripts are worth running once on a fresh clone, because they tell you whether the toolchain is intact on your machine:

```bash
npm run check:types
npm run test
npm run test:e2e
```

check:types runs tsc with noEmit, test runs Vitest, and test:e2e runs Playwright. The repository also configures Storybook on port 6006 through the storybook script.

## Clerk is not a detail you can defer

The most consequential constraint is that authentication is not pluggable. The dependency list includes @clerk/nextjs, @clerk/ui and @clerk/localizations, and the organization member pages shown in the README live under dashboard/organization-profile/organization-members. Roles and permissions in this template are Clerk roles and permissions, and the i18n setup includes Clerk localizations alongside the application's own locale files under src/locales.

If your product needs an identity provider you host yourself, or a pricing model where per-month-active-user billing from an auth vendor is unacceptable, this template is the wrong starting point. Replacing Clerk means rewriting the middleware, the dashboard guards, the organization pages, and the localization wiring. That is not a refactor you do in an afternoon.

Two smaller constraints are worth flagging. The Node 24 engine requirement is stricter than many CI images default to, so a pipeline pinned to an older LTS will fail before it reaches your code. And the build-time migration step means your CI runner needs database access, which rules out build environments that are deliberately network-isolated from production data stores.

## Compared with a Laravel or framework-native starter

The obvious alternative for a team that is not committed to React is a Laravel starter kit, where authentication, teams and roles come from the framework itself rather than from a third-party service. The difference is architectural, not cosmetic. In a Laravel kit, the user table and the team table are yours, the authorization gates are yours, and there is no vendor between your application and its identity data. You pay for that in the language and runtime you have to operate.

A second alternative is to skip the boilerplate entirely and assemble the same stack from its parts: Next.js, Tailwind, Shadcn UI components, Clerk, and Drizzle. That is a reasonable path if your requirements diverge from the template's assumptions early, because you avoid deleting code you did not write. The cost is the setup work this project has already done, including the migration pipeline, the i18n check script that validates locale coverage against the English source, and the E2E suite.

The honest comparison is about how much of the template you expect to keep. If you keep the tenant model, the dashboard and the auth flow, the boilerplate pays for itself quickly. If you plan to replace the auth layer in the first month, you are paying the template's complexity cost without collecting its benefit.

## Licence, upgrades and what maintenance actually costs

The project is MIT licensed, which permits commercial use, modification and redistribution provided the copyright notice and permission notice are retained. That is the standard permissive arrangement, and it is the reason a template like this can be dropped into a closed-source product. The README does not discuss the licences of the third-party services it depends on, and those are separate agreements: Clerk, Sentry and any hosted database you choose have their own terms, and the MIT licence on this repository says nothing about them. That is a distinction worth checking with whoever handles procurement, not a legal question this article can settle.

The upgrade cost is dominated by the dependency surface rather than by the template's own code. The dependency list includes Clerk packages, Sentry, Drizzle, Radix UI primitives, next-intl and the T3 environment validation package, each versioned independently. A major Clerk release can change the shape of the organization APIs the dashboard is built on, and a Next.js major release can change routing or middleware behaviour. The repository ships a check:deps script that runs knip to find unused dependencies and exports, which is useful after you delete template features you do not need.

The last push was on 2026-09-02, and the most recent releases are v1.9.1 from 2026-07-01, v1.9.0 from 2026-06-30 and v1.8.1 from 2026-06-21. The release cadence is frequent enough that pinning a specific version and reading its release notes before upgrading is the practical approach. The README does not describe a deprecation policy or a supported-version window.

## Conclusion

Adopt it if you are building a multi-tenant Next.js product and are willing to let Clerk own authentication and organizations, because that decision is baked into the dashboard, the middleware and the localization files. Do not adopt it if you need a self-hosted identity provider, a non-Postgres database, or a stack that runs without Node 24 on the build machine. Before writing product code, verify three things: that your Clerk plan covers organizations, that drizzle.config.ts points at the database you intend to use in production rather than the local PGlite file, and that the migration in migrations/ applies cleanly against a copy of your real schema. The repository's last push was on 2026-09-02 and the most recent release is v1.9.1 from 2026-07-01, so the upgrade path is active but the version you pin is the version you should read the release notes for.

## FAQ

### What is a SaaS boilerplate, and how does ixartz/SaaS-Boilerplate fit that description?

A SaaS boilerplate is a starting codebase that already contains the parts every subscription product needs, so you begin from a working application rather than an empty directory. This project is a Next.js and Tailwind CSS template that ships authentication, multi-tenancy with team support, roles and permissions, a database layer, i18n, a landing page and a user dashboard.

### What are the best SaaS boilerplates, and where does ixartz/SaaS-Boilerplate fit?

The repository does not rank itself against other boilerplates. What it documents is its own scope: a Next.js and Tailwind CSS template with Clerk authentication, multi-tenancy with team support, roles and permissions, Drizzle ORM across PostgreSQL, SQLite and MySQL, i18n, logging and testing.

### What is a boilerplate example, and is ixartz/SaaS-Boilerplate one?

A boilerplate example is a reusable starting project you clone and adapt rather than write from scratch. This repository is that: the README tells you to clone the project and use it to create your own SaaS, and it points to a live demo at react-saas.com with working authentication and multi-tenancy.
