01 Why ASP.NET Zero

Skip months of groundwork. Start with your product.

Every enterprise application needs the same foundation before its first real feature. ASP.NET Zero hands it to you, proven in production and fully yours.

Starting from scratch

Months of plumbing before your first feature

  • Design login, two-factor and single sign-on
  • Build tenant isolation, editions and trials
  • Wire up subscriptions and recurring payments
  • Create admin screens, settings and audit logs
  • Keep all of it secure and upgraded, on your own

Starting from ZERO

Your team writes product code on day one

  • Authentication, 2FA and SSO, already built
  • Multi-tenancy and editions, ready to configure
  • Stripe and PayPal subscriptions included
  • Admin UI, settings and audit logs out of the box
  • Maintained against every .NET release since 2013
02 AI foundation

AI writes your features.
ASP.NET Zero guarantees your foundation.

AI coding tools are fast, but they generate unproven authentication, multi-tenancy, and billing code. ASP.NET Zero gives your AI agent a battle-tested foundation, so it only writes the features that make your product unique.

01 Proven auth, multi-tenancy & billing your AI doesn't have to reinvent
02 AI rulesets, skills & workflows pre-configured for Cursor, Claude Code, GitHub Copilot, Windsurf & Antigravity
03 An opinionated, layered architecture that keeps AI-generated code consistent and maintainable
