Saasybase Next.js SaaS Boilerplate

You can jumpstart your application development with Saasybase, a production-ready Next.js SaaS boilerplate. This toolkit provides you with essential features, including three authentication providers (Better Auth, NextAuth, Clerk), four payment processors (Stripe, Paddle, PayStack, RazorPay), and built-in support for subscriptions and team management. All of these systems exist as abstracted layers behind shared common interfaces. You also get access to a functional admin dashboard and over 500 automated tests to ensure your project remains robust and stable from day one. Webhooks, transactional emails, secrets management through Infisical or Doppler, an internal ticketing system, email delivery through Resend or regular SMTP, local file storage or S3 for serverless deployments, and local error logging (with optional Sentry integration) are all supported. These features can be enabled or disabled simply by changing environment variables, eliminating (most) unnecessary code at build time. There is also an internal content management system that allows you to create blog articles and static pages on the fly. With most of the heavy lifting already done, you only need to integrate or scaffold your app into the codebase. In many cases, you can simply prompt your app into existence. Structured LLM documentation files such as CLAUDE.md, AGENTS.md, and PATTERNS.md help AI agents understand the entire architecture and workflow of the project.
