The outbreak of the COVID-19 pandemic prohibited radically the collocation and face-to-face interactions of participants in coding bootcamps and similar experiences, which are key characteristics that help participants to advance technical work in coding camps. Several specific issues are faced and need to be solved when running online coding camps, which can achieve the same level of positive outcomes for participants. In this paper, we report on our experience and insights gained from designing and running a fully remote coding camp that exposes high school students to Agile-based Software Engineering practices to enhance their ability to develop high-quality software. To design the online coding camp, we adapted the face-to-face version of the bootcamp to keep the “level of fun” of the face-to-face coding camp, i.e., adaptations aimed at increasing communication, engaging participants, and introducing fun items to reduce fatigue due to prolonged computer use, while preserving the technical curriculum that enables students to attain the learning goals originally planned. The comparison with the results of the face-to-face coding camp shows that the two editions had the same effectiveness in terms of quality of product and process. From our experience, we synthesize lessons learned, and we sketch some guidelines for educators.
