Multiuser earns its spot in the Blender extensions library as a dedicated route to real-time, network-based collaboration in Blender, with more than 8,000 downloads and a version history reaching 0.7.4.
Multiuser is a Blender add-on by slumber that brings a real-time collaborative workflow into Blender. Its aim is to let multiple users work on the same scene over the network at the same time. The add-on is built on a client/server architecture, where a data-oriented replication schema replicates Blender data-blocks across the wire.
Because it moves scene data between machines, the add-on requests network permission to sync that data to the server. Builds are provided for Windows, macOS on both Intel and Apple Silicon, and Linux. Each is added by dragging the package into Blender or using the install-from-disk option in the extensions preferences.
Multiuser runs on Blender 4.3 and newer, with version 0.7.4 as the current release. It is distributed under the GNU General Public License v3.0 or later, and its source is hosted on GitLab. The extension has passed 8,000 downloads on the Blender extensions site. For server setup, connection steps and the full workflow, the developer maintains official documentation and a project page.
Multiuser is best for teams that need multiple people working on the same Blender scene over a network at the same time.
Multiuser is completely free to download and use.
Multiuser is compatible with Blender 4.3 and newer, so you'll need a recent Blender release to run it. The current release is version 0.7.4, and the add-on is added through Blender's extensions system. If you're on an older Blender build, you would need to update before installing. For the exact minimum version and details on each build, the developer's page and version history are the places to check.
Multiuser provides builds for Windows, macOS on both Intel and Apple Silicon, and Linux, so most desktop setups are covered. Each platform has its own download package. The macOS builds are split into separate Intel and Apple Silicon versions, so pick the one that matches your hardware. Grab the package for your system, then drag and drop it into Blender or install it from disk. The developer's page lists each download if you need to confirm the right one.
Multiuser installs by dragging its downloaded package into Blender, or by using Blender's install-from-disk option in the extensions preferences. Downloads are provided per platform, so choose the package for Windows, macOS Intel, macOS Apple Silicon, or Linux. Once added, the add-on requests network permission because it needs to sync scene data to the server. The developer maintains official documentation that covers setup in more detail if you want the full process.
Multiuser requests network permission because it needs to sync scene data to a server. The add-on is built on a client/server architecture and replicates Blender data-blocks across the wire, so multiple users can work on the same scene over the network. A network connection is central to how it operates. For server setup and steps to connect collaborators, the developer's official documentation is the place to look.
Multiuser is listed as free here and is released under the GNU General Public License v3.0 or later. That means you can use it within the terms of that open-source license. Because licensing and distribution terms can change over time, it's worth checking the developer's page for current details before relying on them for a project. The source code is also available through the developer's GitLab repository.
