Building an Instagram-like app in 2025 involves multiple factors influencing the cost. Key expenses include app design, development, testing, and marketing. The technology stack, such as using native or cross-platform development, impacts costs. Features like photo/video sharing, messaging, and social feeds require backend infrastructure and cloud services. Hiring a development team can range widely based on location and expertise. On average, the cost to build such an app could range from $100,000 to $500,000, depending on complexity and additional features like AI or AR. Ongoing maintenance and updates will also contribute to the total cost.
