Supastack

Supastack is a modular foundation for building AI-powered SaaS products. It brings together common infrastructure so developers can focus on product-specific features, with starting points for web, mobile and desktop apps using Next.js, TanStack Start, Expo and Tauri. The kit includes authentication, workspaces, billing integrations for eight payment providers, AI workflows, transactional email, background jobs, analytics, error monitoring and file storage. It is sold as a one-time purchase with lifetime updates, with options for one stack, two repos or the full bundle. Product-specific code remains separate from Supastack’s foundation modules.

Supastack is a modular boilerplate for building AI-powered SaaS products. It brings together common infrastructure such as authentication, workspaces, billing, AI integrations, email, jobs, storage, and observability so developers can focus on product-specific features instead of rebuilding the same foundation for each project. It provides starting points for web, mobile, and desktop apps, with shared TypeScript packages and options for multiple frameworks and payment providers. Users choose a stack or bundle and build on its included repositories and shared packages. The kit provides app starting points for Next.js, TanStack Start, Expo, and Tauri, with modules for authentication, databases, billing, AI, email, and other infrastructure. Apps can use configured AI providers, track usage and budgets, and handle payments through provider adapters. Product-specific features remain in a separate codebase while integrating with the foundation modules. Supastack is for founders and developers building SaaS products, including AI-powered products, across web, mobile, or desktop. The page also describes it as useful to people who want a reusable foundation for new product ideas rather than wiring up login, payments, email, databases, and deployment repeatedly. It offers several stack choices, shared TypeScript packages, setup documentation, and lifetime updates with a one-time purchase.
