Multiple users/mice on one desktop

Each user gets their own mouse pointer and can simultaneously work on the same Windows desktop. Configure each individual mouse (acceleration, cursor theme, wheel and button behaviour etc) independently. Collaboration was never so easy!

Out of beta as of September 26th 2022!

Thanks for waiting and lots of thanks to all of our beta testers!

Simple collaboration

Our goal is to make working together as intuitive and simple as possible. Just add some extra mice and (optional) keyboards and MouseMux will transform your PC into a realtime multi-user system. Each user can work in their own document, annotate on the screen, drag or resize windows or interact with different programs - all at the same time on the same windows desktop. Simple annotations allow each user to highlight parts of the screen. Concurrently interacting with different apps on the same desktop creates new and interesting ways to work together; collaborate by taking over certain actions, type together, draw together - all at the same time without interfering others.


For teams

Use it for pair programming, collaborative designing, in the class or meeting room (so all can interact and have a presence on the screen). Join forces on editing documents, or in the control room so each operator can see where the others are.

For individuals

Use it to customize your (mouse) interaction; custom acceleration, assigned buttons, themes or wheel behavior - for each individual mouse. Record macro's and play them back to automate tasks, even in a multi cursor scenario. Having a cursor for each mouse means you can quickly interact with individual applications because cursors can be localized or dedicated to one program - the restriction of moving one cursor all over the screen and refocusing on a specific application is lifted. The screen's realastate becomes much more manageable.

For industry

In Industrial processes including manufacturing, process control, power generation, fabrication, and refining, and facility processes, including buildings, airports, ships, and space stations where multiple operators work in SCADA like situations safe multiuser operation is vital. MouseMux can manage individual users and can store historical data of any interaction. Assigning a supervisor and overriding actions by other operators is now possible - SCADA programs can integrate with our SDK so true simultaneous interaction becomes possible.

Nothing special. Just plug in some spare mice and keyboards. MouseMux will detect the new devices and automatically add them. Generally what people do is buy a USB hub and use that to plug in more mice and keyboards. Theoretically you can add unlimited devices, we tested up to 32 simultaneous users (64 input devices).
Occasionally a virus scanner will flag MouseMux as unsafe - under the hood MouseMux has a lot of complex behaviour and manipulates the input layer of windows, some virus scanners will find that behaviour suspect and give you an alarm. We're in constant contact with various manufacturers of security tools to keep MouseMux whitelisted. Please drop us a line if your virus scanner flags MouseMux as suspect.
MouseMux generates telemetry to help us understand how it behaves on various systems. All data is anonymized, no personal data is sent to our servers. No interaction data is sent, so no keystrokes, on which window you clicked etc. We’re mainly gathering which features are being used, how long some operations take and what warnings are generated during a MouseMux session. We’ve built a list of all specific data that is sent to our servers – find it at - feel free to contact us if you have any questions or concerns!
All windows versions are supported, from Window XP up to Windows 10, including all the server editions. The program comes in both 32bit and 64bit versions and will automatically select for the appropriate architecture. There is initial support for Windows Apps (UWP) and this will be updated in the coming period. Windows 11 will be tested soon.
Keyboard pairing means linking a keyboard to a mouse – together they represent a (virtual) user. Pairing is simple: move a mouse and hit a key on the keyboard that you want to pair. You will see both the mouse and keyboard light up orange in the row of your user number. Working with paired keyboards may feel unintuitive at first; here’s a use case to explain why. User A and B sit behind the same computer, there are two mice attached and one single keyboard. Both users are interacting with the desktop with their own mouse. User A pairs his mouse to the keyboard. User A clicks on notepad and starts typing. User B takes over and types on the same keyboard. Now user B clicks on some other window and expects to start typing in that window – but since the keyboard is paired with user A, and user A did not click on any other window user B will keep typing in notepad! Practically speaking; user B does not have a keyboard – he/she just follows what the focus window is of user A. This may feel unintuitive because generally you expect to be able to type in a window once you click on it. For this scenario we added an option to synchronize all keyboards (even if it’s just one) to all users – that means mice can operate independently but the keyboard is shared for all users. You can uncheck the Multi Keyboard option in the main UI to disable per-user keyboard pairing – when this option is switched off the keyboard(s) will work just like in normal windows – follow the window with focus to send key data to. Of course, if you have two keyboards and two mice and user A and B are both working on the desktop we suggest to keep the Multi Keyboard option checked and pair each keyboards to an individual mouse so that both A and B can work independently with each a mouse and keyboard.
Yes we have an SDK to allow MouseMux to run in the background (hidden) and create mouse pointers and user via API calls. Please drop us a line for more information.
MouseMux is continually being updated (and will update on your computer automatically). We plan to add networking support so people can remotely join a MouseMux session. We also plan to add screensharing at a later stage. We also have an initial SDK where telemetry for each user is recorded (important in SCADA) and where users can have granular rights. Feel free to drop us a line if you have any cool ideas on how to extend MouseMux!
