About

Nextacular is an open source starter kit designed to expedite the development of full-stack, multi-tenant SaaS applications. Built with modern technologies such as Next.js, Tailwind CSS, and Prisma, it offers a suite of out-of-the-box features to streamline the development process. These features include authentication via magic links and social logins through NextAuth, database integration with relational databases like PostgreSQL and MySQL, and multi-tenancy support to serve multiple customers across different subdomains or custom domains using a single unified codebase. Nextacular also provides teams and workspaces functionality, allowing users to invite team members to collaborate within workspaces. The platform includes a customizable landing page, billing and subscription management through Stripe integration, and simple design components built with Tailwind CSS that can be configured according to your design system.

About

supastack is a modular foundation for building AI-powered SaaS products. It separates common infrastructure—identity, workspaces, Stripe billing, configurable multi-provider AI with encrypted bring-your-own-key support, background jobs, transactional email, audit logging and observability—from product-specific code, letting each project configure the foundation rather than copy another application. It ships as web repositories built with Next.js and TanStack Start, an Expo mobile repository, and a Tauri desktop repository. Developers can configure and extend the source for each product. supastack is sold as a one-time purchase with lifetime updates and unlimited products, rather than as a hosted application for end users.
