Self-managed community soup kitchens play a crucial role in addressing food insecurity in urban-marginal areas, particularly in districts such as Villa El Salvador, Lima, where thousands of low-income families rely on these initiatives for daily meals. However, their impact is often limited by deficiencies in operational management, reliance on manual processes, and low levels of digital literacy among their leaders. These shortcomings generate difficulties in traceability, inefficient resource use, and risks of mismanagement. To address these challenges, this paper introduces MiComedor, a web application developed with the React framework and deployed in the cloud to digitalize the main processes of self-managed soup kitchens. The system integrates modules for inventory, meal portion control, beneficiary registration, budgets, notes, and task coordination, offering real-time access and automated reporting. A user-centered design approach guided the development, prioritizing usability, accessibility, and intuitive interaction through a clear interface suitable for users with limited technological experience. The solution was validated in four self-managed soup kitchens in Villa El Salvador through field experimentation and standardized usability instruments. The results showed excellent acceptance: a SUS score of 91.8/100 and an average USE score of 4.38/5, highlighting improvements in organization, transparency, and operational efficiency. These findings confirm that MiComedor not only enhances management practices but also contributes to digital inclusion, enabling community leaders to strengthen their autonomy and sustainability in contexts of vulnerability.
