This study investigates the challenges of rapid urban population growth and explores how Information and Communication Technologies (ICT) can be used to foster the development of smart cities. It aims to understand how the integration of ICT can enhance urban resilience, promote urban sustainability, and improve citizens' quality of life. The study uses a literature review, appraisals of fifteen Smart City software applications, and thirty case studies across sustainability and resilience. Thematic analysis of the case studies evaluates the benefits of smart city applications mapped to six action areas: Governance, Mobility, Economy, Environment, Living, and People. The findings show that smart city software applications can address challenges like traffic congestion, disaster management, environmental degradation, and community engagement. The benefits of smart city software align with the six action areas, highlighting the role of ICT in urban transformation. The research provides practical applications of smart city software for urban design and planning, emphasizing the influence of contextual factors on Smart City effectiveness. The study advances ICT-driven urban transformation, enhancing the quality of life in fast-growing cities. Smart cities use technologies like software, user interfaces, communication networks, and the Internet of Things (IoT) to tackle sustainability and resilience issues. Smart City software includes data analytics, IoT, urban mobility, energy management, and citizen engagement platforms. The study highlights the importance of smart city software in addressing urban infrastructure challenges, promoting sustainability, and enhancing resilience. The research also discusses the role of technology in smart cities, including the integration of software, infrastructure, and digital data. The study's methodology includes literature review, case study selection, and case study analysis. The results show various Smart City software examples and their applications in sustainability and resilience. The discussion highlights the benefits of smart city software in different domains, including mobility, air pollution, energy management, waste management, and healthcare. The study emphasizes the importance of addressing these areas in smart city development and the need for further integration of digital solutions in diverse sectors. The findings suggest that smart city software can contribute to a more sustainable and resilient urban environment.This study investigates the challenges of rapid urban population growth and explores how Information and Communication Technologies (ICT) can be used to foster the development of smart cities.
