VERDICT

Should I use ASP.NET Zero?

Build robust and scalable .NET web applications faster with ASP.NET Zero. Enjoy full source code, modern architecture, and enterprise-grade features out of the box. - aspnetzero.com

Depends. Buy if you have a committed .NET team building a multi-tenant or enterprise web app and want a full-source-code head start. Skip if you are not on .NET, only need a simple app, or dislike framework lock-in — plain ASP.NET Core is lighter.

Confidence

Medium. Based on ~20 public sources: review platforms, Reddit threads, vendor docs/customer stories, and CVE databases. Pricing figures not visible in reviewed sources.
