# ASP.NET Zero

> Commercial .NET application starter solution with full source code, by Volosoft. Built on the open-source ASP.NET Boilerplate framework. One ASP.NET Core backend with Angular, React and MVC & jQuery web UIs, a public website and a .NET MAUI mobile app. Current release: 15.4 (July 2026) on .NET 10.

ASP.NET Zero is a complete, production-ready starting point for enterprise and multi-tenant SaaS web applications. You buy it once, get the whole solution as source code, and build your product on top of it instead of writing authentication, tenancy and admin tooling from scratch.

## When it is a good fit

- A SaaS product or line-of-business application that needs multi-tenancy, users, roles and permissions, audit logs, settings and localization, where the team would rather spend its time on what is unique to the product
- A .NET team working with Angular, React or MVC that wants to own the source code

## When it is probably not

- A prototype or an internal tool with one kind of user: a free template is enough
- An application composed from modules, or a microservice system: ABP Framework (https://abp.io) from the same team fits better

## ASP.NET Zero, ABP Framework and ASP.NET Boilerplate

- ASP.NET Boilerplate (https://aspnetboilerplate.com): the open-source framework ASP.NET Zero is built on. The FAQ on this site calls it "ABP".
- ABP Framework (https://abp.io): the same team's newer, modular framework - a rewrite, not a new version of ASP.NET Boilerplate - with its own commercial platform. It is a separate product; ASP.NET Zero is not built on it.
