OpenSimulator

OpenSimulator is an open-source platform that allows users to create and run their own 3D virtual worlds, similar to online environments like Second Life. It enables individuals, organizations, or communities to build virtual spaces, host events, and interact through avatars. Because it's open-source, users can customize and extend its capabilities without relying on proprietary software. OpenSimulator is often used for education, training, social interaction, and virtual collaboration, providing a flexible and cost-effective way to develop immersive digital environments tailored to specific needs.
