The History of Umbraco

When did it all start? What has happened throughout the years? And what about version 5?

The story of Umbraco dates back for more than fifteen years. But really, it began on February 16th 2005 when the open-source version of Umbraco was released.

However, before then, a prototype and a mission was born - the mission to create a CMS that’d make it simpler and more delightful for its users to work with, and because of this, also simpler to create amazing digital projects! A mission that still stands today. 

When did it all begin? Is it an “It all started in my parents' garage” kind of story? And has it been a smooth ride throughout the years? 

Let’s find out:

Once upon a time...


Lightbulb icon

  • Niels Hartvig learns about Content Management Systems in his first job straight from High School at "Snabel & Co" where Danish CMS pioneers Lars Buur and Thomas Christensen introduces him to the first Danish Web CMS called Site in A Box.’
  • Niels gets frustrated by the various CMSs he tries and decides to build his own. In 1999, Niels makes the first sketches and prototypes to a simple framework for building and maintaining websites. Umbraco is born - why the name "Umbraco"?


  • Umbraco version 1.0 is announced made in a combo of classic ASP, COM objects written in VB.NET and .NET webservices written in C#. Let's call it the caterpillar version that later transitioned into a beautiful open source butterfly. Most of the concepts known today were here including Document Types, Macros and XSLT. Performance and scalability were definitely lacking though.


  • Umbraco 2.0 which is 100% .NET based is taking shape. The beta version sees the light of day on October 2004.

Umbraco becomes Open Source

  • The first Umbraco Developer conference sees the light of day. It's called Codegarden and a "whopping" 23 developers are attending and talk Umbraco for two days in Copenhagen (some would claim that they spent most of the time trying to install Umbraco).


  • Codegarden is held for the 2nd time - this time with 45 developers gathered in Copenhagen to talk everything Umbraco. 

Most Valued People

  • The very first Umbraco MVPs (Most Valued People) are nominated and they are: Casey Neehouse, Douglas Robar, Jesper Ordrup, Per Ploug Hansen, Thomas Höhler and Warren Buckley.

  • Umbraco version 4.0 is release

  • MVPs: Casey Neehouse, Dirk De Grave, Douglas Robar, Morten Bock, Paul Sterling, Tim Geyssens and Warren Buckley

  • Codegarden: 95 attendees in Copenhagen

  • Number of employees: 2

"Our Umbraco" is born


Umbraco heart

  • The dedicated Umbraco Community site, Our Umbraco, sees the light of day as it is introduced at Codegarden 2009. A platform for strengthening and growing the online developer community. Till this date, Our Umbraco is still the favourite bookmark by every Umbraco developer as it's the place to go if you need technical documentation or want to ask peers about any Umbraco related query. 

  • MVPs: Dirk De Grave, Douglas Robar, Morten Bock, Paul Sterling, Tim Geyssens and Warren Buckley.

  • Codegarden: 140 developers attend in Copenhagen 
  • Number of employees: 3



Hi5 you rock blue bubble

  • "HIGH-FIVE-YOU-ROCK!" or H5YR is introduced for the first time by Chief Happiness Officer, Alexander Kjerulf, at Codegarden 2010. It quickly becomes an Umbraco-way of showing appreciation - whether that's for an awesome Pull Request, some friendly guidance or the launch of an impressive website etc. Today, you'll still find the hashtag #h5yr flying around social media among Umbracians, and at Codegarden, you even get to experience the famous H5YR-rush when hundreds of attendees shout "H5YR" in unison. *Chills*. Dive further into the H5YR-story.

  • Happy five year's birthday! 🎉 On February 16th, more than 300 people in seven places around the world celebrate the five year birthday of Umbraco through community events

R.I.P Umbraco 5


Umbraco lemon

  • Umbraco version 5 was announced dead at Codegarden 2012. Born 2011, time of death: 2012. If you've ever wondered why there is a gap between version 4 and 6, it's because 5 didn't happen. Well, it did, but only very briefly. So, what happened to Umbraco 5? And what happens when life gives you lemons? Read the version 5 "obituary" here

  • Codegarden: 380 attended the Umbraco conference... which turned out to be more of a funeral. 
  • Number of employees: 11

Umbraco moves to GitHub


Blue pointy arrow

  • The Umbraco Source Code becomes available on GitHub. Why is this a great event in history? Because it's what helped make Umbraco much more open-source-friendly as it made it easier for developers to contribute to the source code by creating issues and making pull requests in order to e.g. fix bugs, suggest features etc. In 2013, 250 pull requests were made to the Umbraco core by community members. 

  • Umbraco version 6.0 is released (January)

  • Umbraco version 7.0 is released (November)

  • MVPsLee Kelleher, Jeroen Breuer, Jan Skovgaard, Ismail Mayat, Douglas Robar & Chriztian Steinmeier

Umbraco in the Cloud


Blue Umbraco cloud logo

  • In November 2015, Umbraco as a Service (UaaS) - now known as Umbraco Cloud - is born. "With the Umbraco CMS making it easy to build sites and the community making it easy to share and learn we have a phenomenal combination. But there’s only one thing that’s really been bothering me. More people could build better solutions if they only had to worry about their craft. Not all the tedious things that surround the craft: installing, upgrading, hosting, deployments...But most of all, the uncertainty.” Niels Hartvig 

  • Torben Frigaard Rasmussen steps in as chairman of the board (or the Umbraco cup-bearer). Torben has great experience when it comes to growing start-ups and SaaS companies and wants Niels to continue with his passion and journey when it comes to Umbraco, making him the obvious choice as chairman.
