The 10 Best Development Conferences in Europe

Web conferences are always a great place to network with other like-minded individuals as well as learn about new technologies and best practices. There is a large collection of web conferences happening around the world. Some are more specific in terms of topics they cover and speakers they host, while others are broader and appeal to a wider range of web development groups.

That being said, whether you choose to attend a smaller, niche conference, or a larger, more general conference, there are benefits to both. Being based in Switzerland, here at KeyCDN, we tend to visit web development conferences held in Europe. We believe that it's important to be as close as possible to the community and our customers, not just virtually but also physically.

That's why in this post we've compiled a list of some of the best web development conferences in Europe.

The best web development conferences in Europe

The following list is not ordered in any particular fashion. Each conference brings its own set of benefits to those in the web development industry. Visit the linked conference web page if one peaks your interest and check the list of speakers/topics (if available) to see if they are of interest to you.

1. Velocity

This is O'Reilly's technology conference about web performance, dev ops, and scalability. With the slogan "Build resilient systems at scale", this three-day conference is a must for web performance experts. The attendees are mostly developers, sys admins, architects and tech leaders.


The Open Source Conference (OSCON) is also one of O'Reilly's technology conference which is now hosting its 20th year. Like many conferences, this one changes locations and this year it is based in the US. However, the organizers do base it out of Europe from time to time making it a great conference for those who are near.

For everything open source related, OSCON is the conference to be at. Open source software is an important component of KeyCDN's architecture and we're happy to join that community.

3. code.talks

This is one of the biggest developer conferences in Europe created by developers for developers. Code.talks started in 2010 and has grown to over 1500 attendees. Over 110 presentations take place within two days.
