What is C++Online?

C++Online is an online only, international C++ Conference which will run from 28th February - 2nd March 2024, with the main conference running on the 29th Febuary - 2nd March with online workshops before and after the main event.

C++Online is brought to you by the organising team behind C++OnSea and the technical team behind online and hybrid versions of CppNow, CppCon, ACCU, The Audio Developer Conference and many other established events.

The conference is designed to provide a more accessible option for those who might find attending other international conferences more difficult or financially restrictive, at a time of year where we traditionally see less in-person conferences due to weather, holidays and other restrictions.

Join us online for four days of C++ content, including livestreamed C++ talks and workshops, group chats, networking and meetups through our interactive virtual venue, meet sponsors, recruiters, peers and experts in the field through video and text chat in Zoom, Discord and Gather Town.

The conference will run from 12:00-22:00 UTC with the main programme of talks scheduled to be accessible to as many active time zones as possible. In addition, all sessions will be available to watch on-demand through the conference web portal. We'll also have lightning talk sessions, virtual poster sessions and other content available to participate in throughout the event.

There will also be opportunities to schedule your own content, such as group discussion sessions, open Q&A sessions, meetups or BoF group chats in our virtual venue!

Check out our schedule of talks and workshops.

Unlike Open Content and Online Posters, all lightning talks will be recorded and published to the C++Online YouTube channel after the event.


Conference Systems & Features

The key systems and features of the C++Online Conference are listed below.

Virtual Venue (Gather Town)

An exciting, interactive, online conference experience awaits you in our virtual venue.

  • Watch Talks With Other Attendees - Like at an in-person conference, you can watch the online talks from presentation rooms in Gather Town.
  • Interactive Group Video Chat - Use the Proximity-based Video & Audio Chat for spontaneous interaction with attendees like in a physical venue
  • C++Online Quiz Hunt - Take part in our virtual puzzle game by hunting down pub quiz questions hidden in objects around our virtual venue.
  • Interactive Objects - Play piano (even as a duet), enjoy embedded games, materials and other fun activities


Discord is a free-to-use text and audio based discussion app that is available as a website, mobile and desktop app and will be used as the support and communication system for the conference. You can chat with speakers and attendees before, during and after each session at the conference and access live support from one of our online volunteers if you run into an issue.

Zoom Webinar

All of the main conference sessions will be streamed online through Zoom Webinar which allows us to provide the highest quality stream possible and to facilitate the on-demand access to each session. However, to create a more interactive experience, speakers will be encouraged to take questions for their talk in our virtual venue which allows attendees to video chat with the speaker.

Conference Platform / Portal

While attendees will be encouraged to use Gather Town to attend main conference sessions, we also have a user friendly website that can be used as an alternative for anyone who either has an accessibility issue or that is unable to connect to Gather Town. In addition, this website also hosts the schedule for the event and allows for users to create personal agendas for the event.
