View Source Conference



Buy your ticket now

Join us for our fifth View Source conference in Amsterdam on September 30th and October 1st of 2019.

This year, we are expanding View Source to bring you a deeper dive into how browser vendors, and others, create and support web standards, as well as best practices for building for the web.

View Source Amsterdam was formed in collaboration with our friends at Microsoft, Google, Samsung, and W3C to provide a dive deeper dive into the workings of the web. Over two days, we’ll feature visionary speakers, discussion areas and Q&A with engineers, our event partners and others across the industry, through collaborative breakout sessions and engagement programs we call Conversation Corners. View Source also provides opportunities to connect with and learn from like-minded people in a collaborative, inclusive environment.

We will have live captioning and reserved seating available.

Monday, September 30th


Registration opens, light breakfast and coffee


Opening Keynote: The Shape of the Web
Henri Helvetica

“The Shape Of The Web” is about both accomplishments and challenges that lay in the past and present of the web. In his opening keynote, Henri Helvetica looks back in time and forward into the future, at the technologies the web has employed, but also at the future of its employed technologists.

He remembers the textual academic web of the early 1990s, and the sea change that came when a browser allowed for both text and images to be displayed in the viewport. And he identifies some of today’s challenges in ensuring that the “gateway to the riches of the internet” remains open and inclusive for all.

A case for browser-engine diversity in a decreasingly diverse browser-engine world
Mike Taylor

Given the recent demise of Presto and EdgeHTML rendering engines, and dominant market share growth for Chrome (and its Chromium engine), can we make a case for browser engine diversity in a decreasingly diverse browser engine world? In this talk we’ll talk about web compatibility, interoperability, the web standards process, and hopefully conclude that we should care about these things in 2019.


Is the site fast yet?
Sharell Bryant

As the owners of web performance, my team is often asked some version of the question “Is the site fast yet?”. While it sounds simple, it's actually impossible to answer without asking more questions. “Is our site fast in New York but slow in Sydney? Is it fast on all devices or just on desktop? How fast is fast enough and most importantly, what does fast even mean?”. In this talk, I’ll share what we've learned while finding an answer to this question, including how to conduct a performance audit, how to talk about performance with your teammates outside of engineering, and how to advocate for your users by making performance a priority.


Demystifying Speed Tooling

This talk will provide an overview on how to effectively assess and optimize site performance using a slew of industry grade tooling. Learn how to methodically diagnose, benchmark (against both lab and field metrics), and monitor your site speed using these tools.

Demystify Modern CSS Layouts with DevTools
Hui Jing Chen

Flexbox, Grid and Box alignment properties are powerful and versatile new additions our web development toolkit. However, they may be slightly confusing to wrap your head around if you do not completely understand how browsers interpret the CSS values you assign. Although we tend to associate DevTools with debugging, Firefox DevTools comes with features that can help visualise how these properties work and better understand what's going on as the viewport size changes.

Web Monetization: An Alternative to Ads
Stefan Thomas

Independent creators on the web today are increasingly forced into a handful of content platforms. Web Monetization is a proposed new web standard which provides an alternative to ads and site-by-site subscriptions. It has the potential to level the playing field between indie creators and giant tech companies.


Jeremy Keith

Every new medium looks to what has come before for guidance. Web design has taken cues from centuries of typography and graphic design. Web development has borrowed metaphors and ideas from the world of architecture. Let's take a tour of some of the most influential ideas from architecture that have crossed over into the web, from pattern languages to responsive design. Together we'll uncover how to build resilient, performant, accessible and beautiful structures that work with the grain of the materials of the web.

    The State of WebXR

    There is a battle today between centralized walled gardens app ecosystems and the decentralized open web, and the development of open standards for an immersive metaverse have been evolving over the past 5 years through the WebXR specifications. We've all imagined what the science fiction depictions of the metaverse in Snow Crash and The Oasis in Ready Player One might look like, but how close are we to realizing the first iteration of an open metaverse that's build upon the spatial web?

    Come listen to a live discussion with some of the architectural visionaries who have been designing the future of spatial computing where the world will become our operating system. How close are we to having the specifications locked down? What are some of the biggest challenges and open problems yet to be solved? Join the Voices of VR podcast host Kent Bye and a panel of experts who will be exploring the amazing potential or what the future of an immersive open web will enable.

Lightning Talks

Tuesday, October 1st, 13:00

View Source brings a special lightning talk presentation session on Day 2 starting at 1pm. Submit your lightning talk on your wants for the web! Selected participants will be notified via email to have 5 minutes to present their wants to an expert panel of judges and our live audience on stage.

What “wants” are we looking for? Well, if you build websites, you inevitably run into problems. Maybe there’s no way to achieve an aspect of your design using CSS. Or maybe there’s a device feature you really wish you could tap into using JavaScript. Or perhaps the in-browser DevTools don’t give you a key insight you need to do your job. We want to know your pain.

Best of all, the top problems selected by judges and one audience favorite will win awesome prizes!
