Budget the cost of a virtual conference that's right for you.
If you choose to use our organizing tools for your conference (website creation, program maker, management of participants, abstract/registration handling, ...) and not run the conference with us then it is all free.
If you run the conference with us, then our pricing includes a carbon offset for each organized conference to limit the impact of research activities on our Planet. Therefore, the pricing is mostly set by the number of people participating to the conference and the number of days it lasts. It also depends on whether one wants to record and keep the conference video accessible online. Note that the conferences with less than 50 participants lasting for less than 3 days are free (except for carbon offsetting fees, which you can do on your own and send us the certificate or offset directly on our website).
