The Minimal ASP.NET Boilerplate for Solo Developers & Small Teams

A simpler alternative to the ABP framework. Nano gives you a clean, unopinionated foundation based on industry-standard .NET patterns—without forcing you to relearn everything.

Faster Time to Market

Skip weeks of repetitive setup. Start with authentication, multi-tenancy, authorization, infrastructure, and working UI templates already integrated

Industry-Standard Patterns

Build on code you can understand and extend. Clean architecture, dependency injection, repository patterns, async programming, and established ASP.NET practices.

Fully Documented

Spend less time figuring out complex framework abstractions. Comprehensive guides, clear code comments, and explicit architecture help you stay productive from day one.

Unlimited Developer License

Build as many projects as you want. Use Nano as a reusable foundation for unlimited SaaS applications, internal tools, and client MVPs with lifetime access and updates.

A Production-Ready Foundation

Skip the repetitive setup that comes with every new application. Nano gives you a structured ASP.NET foundation so you can start building your product immediately.

Multi-Tenant by Design

Build SaaS applications with optional tenant isolation already built into the architecture. Choose between single-database, multi-database, or single-tenant options depending on your security and scaling requirements.

Authentication & User Management

User login, registration, roles, permissions, password reset flows, and profile management pre-configured for both API (JWT) and Razor Pages (Cookies).

Essential Application Infrastructure

Get the supporting infrastructure most applications need, including email, file and image handling, exports, DTO mapping, and data access patterns. Includes fully integrated starter UIs for Vue, React, and server-rendered Razor Pages.

CLI Project & Code Scaffolding

Generate clean, customized projects, CRUD services, and controllers on demand. Create a ready to use starting point instead of manually modifying an old codebase.

AI-Ready & Unopinionated

Zero proprietary framework lock-in. Clean, standardized code conventions make it easy to drop in third-party AI APIs, LLM orchestrations, or custom integrations.

Build Products, Not Boilerplate

Nano gives you a proven ASP.NET foundation for building SaaS products, B2B platforms, and internal business tools. Choose your frontend, configure your application, and spend less time rebuilding the infrastructure every project needs.

Get from Idea to Application Faster

Every new web project requires repetitive plumbing before you can focus on your actual product. Nano provides a structured application foundation from day one, so you can get to your custom features faster.

Start with a clean ASP.NET Core Web API and architecture setup
Bypass redundant security, identity, and user management setup
Reduce time-to-market for SaaS MVPs and commercial applications
Focus your time on high-value business features

Built-in Multi-Tenancy Architecture

Multi-tenancy can become complicated quickly when it is added to an application later. Nano puts it at the center of the architecture from the beginning.

Isolate customer data across shared or dedicated databases
Choose the tenancy configuration that fits your application
Manage tenants and tenant-specific functionality from a central foundation
Adapt tenant behavior without fighting rigid third-party frameworks

Choose the Frontend UI That Fits Your Workflow

You shouldn't have to change your preferred development approach just to use a boilerplate. Nano includes complete front-end projects for Vue, React, and Razor Pages.

Build a modern SPA with Vue or React
Traditional server-rendered UI option with ASP.NET Razor Pages
Includes client/server data tables, dark/light themes, forms, and layouts
