So much better than ABP

Darren Rose, January 11, 2025

So much better than the previous template I was using (ABP), responses from company really quick and very helpful. Would highly recommend

Great product!

Julian, January 31, 2025

I was looking around for a boilerplate for .NET and found the only options were ABP which was way too complex for my needs, or open source projects with non-existent documentation. The Nano ASP.NET Boilerplate was exactly what I needed. It’s allowed me and my team to jumpstart our build. It has easily saved us a month in development time.

Great boilerplate

Gera Kourtidis, October 16, 2024

Very easy to follow the docs. Videos on Youtube very helpful.

Great reply time

Rodolfo Menéndez, August 31, 2024

Great reply time, I had some trouble with EF using the wrong version and they helped me solving this online. I'm looking forward to make some exceptional software using Nano as the main API because I'm deploying on a Blazor FrontEnd. Easy to learn, comments all over the project to help the developer, not bloated and it has a CLI.

It's even better than I'd expected...

Dave Mueller, August 31, 2024

When I set out to learn multi-tenancy in the .Net ecosystem, I happened upon the Nano ASP.Net Boilerplate during an internet search for a .Net multi-tenancy developer solution. After checking out the boilerplate and being impressed by their developer docs, I decided it seemed well worth a leap of faith to purchase the full product. What a smart choice that turned out to be! Not only has the boilerplate been more than I'd hoped in terms of a productivity boost, it's been very educational as well. Simply put, I learned a lot from the architecture and patterns employed within the boilerplate solution. I feel like I've grown a lot as a developer in recent months because of having made the choice to purchase the boilerplate. In addition, I am getting close to a production release of my first multi-tenancy SaaS product thanks to the productivity boost and understanding the boilerplate has given me. My review is 5 stars because I would be nowhere near as close as I am right now to meeting ...

Multi-Tenant made easy!

Casey Spaulding, June 03, 2024

I’ve been using ASPnano for my multi-tenant web application, and it’s been a game-changer. The framework is lightweight, yet powerful, making it easy to set up and manage complex multi-tenant environments. The documentation is thorough, and the support is outstanding. The built-in features for handling authentication, authorization, and tenant management streamline development, allowing me to focus on delivering value to my users. Highly recommended for anyone looking to build scalable, efficient multi-tenant applications.
