Technology plays an essential role in promoting socioculture by facilitating access to information, fostering intercultural communication, preserving cultural heritage, promoting citizen participation, and stimulating artistic and cultural creation. The objective of the research was to develop a web application for the sociocultural dissemination of the municipality of Lamas. For the development of the application, we used the agile methodology of Extreme Programming (XP), covering the phases of (I) exploration, (II) planning, (III) iterations towards the first release, (IV) deployment, and (V) maintenance; to evaluate the system’s usability, we used the System Usability Scale (SUS) survey applied to a sample of 30 end users. As a result, we obtained a robust web application, with modules that met the users’ needs, an intuitive and simple interface; and the usability test result was acceptable. We conclude that the development of the web application for sociocultural dissemination represents a valuable tool that contributes to promoting the cultural heritage of the region, allowing potential visitors to explore and plan their trip in a more informed manner.
