What stands out

A quick read of the recorded project description.

Uses the Next.js /app directory and React to build pages and routes

Integrates Lucia Auth, covering registration, login, logout, email verification, and password recovery

Account settings support changing username, password, email, timezone, language, and appearance

The project module includes creation, renaming, deletion, and member invitations and role management

Connects to PostgreSQL via Prisma as the data layer

Billing integrates Tier and Stripe, supporting subscriptions and Checkout

Template Details

nextjs-saas-starter is an open-source starter for SaaS scenarios, using Next.js's /app directory to organize pages and routes, paired with React. The data layer uses Prisma as the ORM, connecting to PostgreSQL; authentication is provided by Lucia Auth; billing integrates Tier and Stripe, supporting subscriptions and the Checkout flow, with pricing models configured through the Tier Model Builder. Styling and UI use tailwindcss and shadcn.

According to the README's completion checklist, the authentication module covers registration, forgot password, change password, email verification, login, and logout; the account module supports changing username/name, password, email (with confirmation), timezone, language, appearance, and deleting the account (restricted when the user is a project Owner). The project module supports creation, renaming, deletion (the restriction that only the Owner can delete is not yet complete), and member management supports invitations (create invitation, send email, accept invitation, remove invitation), removing members (non-Owners can leave on their own), and changing roles. The billing module is not yet checked off as complete in the checklist.

The repository README explicitly states "it's still a work in progress," so this template is better suited as a starting point for learning or secondary development rather than a ready-to-launch product. Running locally requires copying .env.example to .env.local and configuring the corresponding environment variables; the repository also provides a Docker Compose configuration, using mailpit for local email development.

Usage conditions & limitations

Free to use · keep license notice

This entry covers the free version under the MIT license in the public repository; the free scope is the code of this version and does not mean external services or third-party assets are free.

Must comply with when using

Free use, modification, commercial use, and distribution of this version's code are permitted.
When distributing copies or substantial portions of the code, retain the original author's copyright notice and the full MIT license notice.
The code is provided as is; warranties and limitations of liability are governed by the original license and applicable law.

Additional costs & items to verify

Billing features depend on third-party services Tier and Stripe; using subscriptions and Checkout requires registering the corresponding accounts and configuring API keys, which may incur service fees.
Authentication is implemented based on Lucia Auth; deployment requires configuring session and authentication-related environment variables yourself.
The data layer uses Prisma, requiring a PostgreSQL database connection and connection string configuration.
Local running requires copying .env.example to .env.local and filling in the required environment variables; otherwise it cannot start properly.
Local email development depends on the mailpit service, and email-related features require this service.
The project README states it is still in progress and the billing module is incomplete; features may be incomplete and it is not suitable for direct use as a production-ready product.
Demo images, fonts, icons, and other third-party assets must be checked against their respective licenses and cannot be judged solely by the code's MIT license.
External services such as domains, hosting, databases, payments, or AI may incur additional charges.

How this score is calculated

Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.

What to verify for this project

A demo link is listed. Check it with your own content and viewport sizes; its presence does not confirm that forms, authentication or payments work.

The catalog identifies Next.js as the primary stack. Check the actual dependency manifest and lockfile for versions and hosting requirements. These notes use recorded metadata, not a code audit or a deployment test.
