This paper presents a gravastar model developed within the framework of f ( Q ) gravity using the Durgapal metric potential, allowing for a smooth and regular spacetime throughout the entire configuration. The model is structured with three distinct regions that include a central core filled with dark energy having negative pressure, a surrounding shell made of ultrarelativistic stiff matter, and an outer region that follows the Schwarzschild solution. By solving the modified field equations, we obtain exact expressions for physical quantities such as energy density, pressure, and metric components. The analysis focuses on the shell region, where proper length, total energy, entropy, and surface redshift are examined to understand the physical nature and stability of the configuration. Numerical values are determined using observational data from the compact star Vela X1, showing that the model remains free from singularities and does not form an event horizon. These results suggest that gravastars described in f ( Q ) gravity offer a meaningful and realistic alternative to black holes and provide valuable insight into the study of compact objects through modified theories of gravity.
