For over 15 years, the ClueCon Developers Conference has been dedicated to helping the FreeSWITCH team and other software engineers “get a clue.” Getting a clue never comes easy and takes years of hard work and dedication, but the ClueCon team is committed to working with the community to continue educating, networking and “getting a clue”.

ClueCon is where it all began. The idea of FreeSWITCH was thought up at the first ClueCon in 2005; the plan was born based on the ideas that were bounced around during that first 3 day conference. The core members of the team worked hard for the next 12 months, and FreeSWITCH was presented for the first time at ClueCon 2006.

The first ClueCon conference was held in 2005 and over the years has grown with help from our sponsors, attendees and the members of the open-source community. ClueCon is held in Chicago, Illinois, annually.

Coder Games:

The Coder Games are ClueCon’s version of a hackathon with a few surprises thrown in. We invite our attendees to participate in several fun challenges for people of all technical skills. The Coder Games are a great way to meet people in a relaxed environment: try your hand at building popsicle stick contraptions or dig into some API’s!

Yes, anyone who is attending ClueCon can sign up for the Coder Games. Coder Games is included in your conference registration. You can participate in as many or as few challenges as you like, or join as a spectator.

We encourage all forms of participation!  Observe, assist, eat a snack, or get some work done. Demos take place throughout the afternoon and are always a blast to watch.

We encourage everyone to participate  in the Coder Games and do not have an official registration: just hop in and participate! You can either speak with a team leader for help, or follow the written instructions on the table. When you submit a challenge to the judges you are officially eligible to win a prize. However, when you register for ClueCon, it is helpful to check whether or not you will be attending the Coder Games so that we can better plan for the event.

You can participate in as many or as few challenges as your heart desires.

We accept solo entries as well as teams of all sizes.

We provide a plethora of materials to work with, but it’s not against the rules to Amazon Prime a thing or two. Be as creative as you can to score one of the coveted prizes.
