Clean Architecture Solution Template vs Modular Monolith with DDD

Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.

A .NET project template that generates a starter ASP.NET Core app with Clean Architecture layers.

Modular Monolith with DDD

Open source · MIT

A sample .NET application showing a modular monolith built with Domain-Driven Design, meant as a reference imp

The short answer

Choose Clean Architecture Solution Template if you need…

  • Developers starting a new ASP.NET Core web app or Web API who want a structured layout
  • Teams that want a Clean Architecture starting point with a chosen database and frontend
  • .NET developers learning how layered architecture is laid out in a real project
  • Developers who want SQLite by default for quick local work without Docker

Choose Modular Monolith with DDD if you need…

  • Developers learning Domain-Driven Design tactical patterns in C#
  • Teams comparing modular monolith structure against microservices
  • Engineers wanting to see CQRS and unit and integration tests applied together
  • Students studying architecture decisions in a realistic codebase

What each one is

Clean Architecture Solution Template

This is a solution template for the .NET CLI. It creates a new ASP.NET Core project organized into Clean Architecture layers, with an optional Angular or React frontend and a choice of SQLite, PostgreSQL, or SQL Server as the database. It is meant as a starting point so you do not have to set up the project structure yourself.

Modular Monolith with DDD

This is a complete example application written in C# for .NET, organized as a modular monolith: one deployable program split into separate modules with clear boundaries. It applies Domain-Driven Design, a way of structuring code around the business domain, and uses a Meeting Groups domain modeled on Meetup.com. The README says its purpose is to show these architectural ideas in a full, production-oriented implementation rather than a small demo.

Best for

Clean Architecture Solution Template

  • Developers starting a new ASP.NET Core web app or Web API who want a structured layout
  • Teams that want a Clean Architecture starting point with a chosen database and frontend
  • .NET developers learning how layered architecture is laid out in a real project
  • Developers who want SQLite by default for quick local work without Docker

Modular Monolith with DDD

  • Developers learning Domain-Driven Design tactical patterns in C#
  • Teams comparing modular monolith structure against microservices
  • Engineers wanting to see CQRS and unit and integration tests applied together
  • Students studying architecture decisions in a realistic codebase

Strengths

Clean Architecture Solution Template

  • Installs as a standard .NET template with a documented command and options
  • Lets you choose frontend and database at creation time, with SQLite as the default
  • Includes a published documentation site and architecture decision records

Modular Monolith with DDD

  • The README describes it as a full application with features like authentication and tests, not a toy example
  • Documents architecture decisions, C4 diagrams, and testing approaches in detail
  • Open source under the MIT license with a large community following

Not ideal for

Clean Architecture Solution Template

  • Developers who do not use .NET or C#, since the template only generates ASP.NET Core solutions
  • Anyone wanting a minimal single-file app, because the template generates a multi-project solution
  • Teams needing a non-.NET stack; the README covers only ASP.NET Core

Modular Monolith with DDD

  • Readers who want a quick, minimal starter project, since the README says it is intentionally a full application and not a simple one
  • Anyone needing a deployment guide, since the README lists deployment and infrastructure as out of scope
  • Teams looking for strategic DDD guidance, since the README explicitly excludes strategic patterns

Trade-offs

Clean Architecture Solution Template

  • Generates a sizable multi-project solution, which may be more structure than a small app needs
  • Using SQL Server or PostgreSQL requires Docker or Podman, per the README
  • The README is truncated here, so details beyond the setup steps are not fully verified

Modular Monolith with DDD

  • The README says deployment, containerization, and infrastructure are out of scope, so you will need to work those out yourself
  • The README states it reflects one of many valid approaches, so it should not be treated as the only correct design
  • The last push in the metadata is from June 2024, so check whether it still fits your current .NET version

Getting started
