Nano ASP.NET Boilerplate

A minimal ASP.NET Core API boilerplate that provides a starting point for building multi-tenant SaaS applications, solving the problem of repetitive setup and infrastructure coding. It targets individual developers and small teams who need to build B2B SaaS or MVPs quickly. The boilerplate includes clean architecture, authentication, user management, and multi-tenancy, and is positioned as a simpler, unopinionated alternative to the ABP framework, with support for Vue, React, and Razor UI projects.
