Our paper studies a novel gravastar model, building on Mazur and Mottola (M-M)'s work, within Lorentz-violating gravity configurations, focussing on the Horava gravity and Einstein-aether theory. The M-M mechanism forms the basis for gravastars, a potential black hole (BH) substitute. This approach facilitates a three-stage model for the gravastars. Our modeled structure includes three regions: an inner region, a thin shell with ultra-relativistic fluid and the outer vacuum region and our obtained solutions for all the regions have supported the viability of our model. Different physical features for the shell region has been gone through in our study which have characterized our gravastar structure. We have shown our thin shell model's stability through the energy condition analysis which has enhanced its physical acceptability. Thus, our research has yielded singularity-free gravastar solutions avoiding the event horizon in Horava gravity and Einstein-aether theory producing an alternative to the classical BH theory.
