Today most AR experience developers are focusing all their efforts on delivering AR experience content through Android, iOS, Magic Leap or HoloLens applications. The apps need to be published and users have to find them.

In the future, however, AR experiences will be increasingly published by Web developers and the Web browser (running on many different form factors for AR display) will replace native apps for the delivery of rich AR experiences.

Users will interact with the real world and digital content in Chrome, Firefox, Microsoft Internet Explorer or the Samsung internet browser. See the list of browsers that currently support portions or full WebXR functionality here

During this hackathon, creators of all levels will form teams and collaborate on making geospatially-anchored WebAR experiences.

This site will help you plan your participation, get acquainted with the datasets we have collected and register to participate in this hackathon. You can also learn about the challenges that we have designed for teams to tackle!

In the spirit of learning efficiently and sharing back with the community participants will be invited to use free, libre and open source (FLOSS) tools. Participants should consider sharing back their work openly (e.g. creative commons) at the end of the event on this very website.

Check the Challenges for now.

  • Have you or your audiences been experiencing Mobile Augmented Reality App Fatigue? Are you looking for an alternative to pointing people to their app store where they must download an app for every object or place that could be discovered or revealed in more depth and with engaging AR experiences?
  • Are you one of the millions of content or experience creators who seeks to provide greater value and share you or your company’s knowledge, data or instructions in context in the most intuitive and lightweight manner with the lowest possible friction and without losing control?
  • Have you been envisaging ways to combine digital assets from multiple sources into a single, easy to manage, coherent window overlaying the real world?

The answer is coming

We are at the cusp of a new era in which a standards-compliant web browser will replace the need for (or be complementary to) native AR apps as they are being published today. A web browser is all that will be needed for the delivery of fully interactive, rich and rewarding AR experiences to users holding a variety of AR display devices.

What are we waiting for?

Between now and when AR will be just as natural for users as 2D text on a page is today, Web developers will learn how to author experiences (for use in the real world that will include 3D) and AR developers will learn/get used to designing experiences for audiences who use only a Web browser as their AR experience viewer.

Wait no more

Everyone who wants or needs to get a jump start on this exciting frontier of our digital era should participate in the first Web-based AR Hackathon late June 1-2 in Belgium. During this hackathon, creators of all levels will form teams and collaborate on making AR experiences which can be viewed in these browsers.

Challenges You and your team will be invited to prepare your best AR experiences in one of the following five challenge categories.

Public Sector

Teams choosing this challenge will identify a public place or facility near the hackathon venue and an open data set. Using these assets and digital content of their choice the team will design experiences that demonstrate use of AR for citizens or professional managers in any level of government of cities.


Teams choosing this challenge will illustrate the use of AR by health professionals (capture of real world conditions, AR-assisted diagnosis, treatment in any clinical setting), and/or any rehabilitation or wellness use cases.

Architecture & Construction

Teams choosing this challenge will identify a specific public space in the Microsoft Reactor space (where the hackathon is being hosted) and design experiences that demonstrate the use of AR by professionals performing tasks in building, maintaining or repairing the built environment.


Teams choosing this challenge will select an object of any type or dimension, or a catalog of any products and design experiences that demonstrate use of AR for shopping and e-commerce.


Teams choosing this challenge will identify a real world learning opportunity and demonstrate the use of AR to convey information and/or to teach about complex topics.
