The article aims to find out the specific features of the use of interactive web platforms for developing components of communicative competence of future specialists in various fields. The study used testing, observation, and experimental procedures. The sample was from students majoring in Secondary Education, Philology, and Journalism. The study confirmed the hypothesis about the effectiveness of using web platforms to develop future specialists' communicative competence. The average indicators of communicative competence's cognitive and activity components prevail in the studied future specialists. At the same time, communication skills are not sufficiently developed. Significant positive changes have been recorded in the cognitive and activity components of communicative competence. The motivational component remained unchanged due to the formative impact – a decrease in the fear of rejection was found only in the group of future teachers. In general, the developed online program does not significantly depend on the specialty, as the developed exercises have already considered the specifics of a particular area of training. The obtained results can be used to optimize forming communicative competence in higher education. Thus, the conclusions about using web platforms to develop communicative knowledge and skills of future specialists are practically valuable. Further research could address prospects in expanding the range of specialties studied and clarifying the data obtained by comparing them with the results of the control groups.
