Blend Online lets two or more people edit the same Blender scene at the same time, over the internet, with voice and text chat built in. Send one invite code and start working together: no server to set up, no port forwarding.
Objects, meshes (live in Edit Mode and Sculpt Mode), curves, materials and shaders, textures, modifiers, Geometry Nodes, constraints, collections and animation stay in sync. Voice chat runs on Windows and Linux. Invite code connections work through most routers; when both sides are behind a strict NAT, use the included relay server script or a VPN. Requires Blender 4.2 or newer. Each person in a session needs the add-on.
