It Started With a Pattern

Circle Graphic
2009

In 2009, Dominick Baier was implementing security systems for customers and kept noticing the same problem: every organization needed a token service, and everyone was building it from scratch. So he wrote a framework consisting of a humble collection of seven files called StarterSTS.

Around the same time, Dominick reconnected with Brock Allen, a .NET and application security specialist. They shared a belief that identity infrastructure should be built with precision, with standards, and with developers in mind.

From side project to standard.

2014

Over a decade of relentless iteration, Brock and Dominick built something remarkable: an open-source OpenID Connect and OAuth 2.0 framework that gave developers something no SaaS product could: complete control.

The .NET community took notice. IdentityServer became part of the .NET Foundation. Microsoft adopted it as the token plumbing for their Angular, React, and Blazor templates. Downloads surpassed twelve million on NuGet.

2020

As IdentityServer adoption grew, so did the need for a sustainable model to support production systems worldwide. The organizations relying on IdentityServer for mission-critical systems deserved more than a passion project, they deserved infrastructure with a foundation as solid as the software itself.

Duende Software was born as the commercial home for IdentityServer, built to support enterprise-grade customers without sacrificing the developer control that made the original project iconic. From the start, the goal was simple: help developers build identity systems the right way. Over the past decade, that work—and the contributions of a growing team of engineers and identity experts—has helped shape how modern identity systems are built.

The name came to Brock during a sleepless night watching a Miles Davis documentary - the Spanish word duende, meaning the heightened state of authenticity that comes from performing your craft at the highest level.
