If you're looking for a Volu alternative, Bezi is another good option. It's a collaborative spatial design platform that accelerates the 3D design process, letting teams design, prototype and review 3D apps and games faster. Bezi has more-advanced features like generative AI, developer handoff and AR/VR headset support, but it's designed to be accessible even to people without strong 3D skills. It also has features like real-time collaboration, Figma integration and tiered pricing plans.
Another good alternative is 8th Wall, a collaborative environment for building and publishing web-based augmented reality (WebXR) and 3D experiences. The platform lets developers build experiences that are accessible through ordinary web browsers, not separate apps. It can be used for a variety of use cases, including games, e-commerce and entertainment, so it's a good option for many industries.
If you prefer a more coding-centric approach, check out Zed. This high-performance, multiplayer code editor combines the power of an integrated development environment (IDE) with the responsiveness of a lightweight editor for better productivity. It's got features like AI-powered code generation, an integrated terminal, Vim mode and advanced collaboration abilities. Zed supports languages like Rust, TypeScript and Python, so it's a good option for developers.
