Mouse and keyboard sharing software compared (2026)

Q: Is there free mouse and keyboard sharing software?

Yes. Mouse Without Borders (Windows only, part of PowerToys), Deskflow (Windows, macOS, Linux; open source), and ShareMouse Free (two computers, personal use) cost nothing. The OneMouse Windows and Mac apps are free as well; the OneMouse Android app has a Free tier with ads and daily clipboard and file limits, and a one-time Pro unlock removes them.

Q: Controlling an Android phone from a PC: is that a mirror window or a real cursor?

They are different things. Mirroring tools such as scrcpy, Vysor, and Phone Link show the phone screen in a window on the PC and you click inside that window. Edge-crossing tools such as OneMouse and Samsung Multi Control send the PC cursor onto the phone's own display, so the phone behaves like an extra monitor. OneMouse works by edge crossing and also offers an optional remote-control window.

Q: Does OneMouse need an account or a server?

No. Devices pair locally with a 6-digit code or QR code (a PIN with SPAKE2 key exchange), and input, files, and clipboard data move directly between your own paired devices. There is nothing to sign in to and no relay server.

This page answers one question: which mouse and keyboard sharing software fits your desk? It puts OneMouse next to the tools people usually consider, from PC-to-PC software KVMs to phone-control utilities and vendor ecosystem features. OneMouse is our own product, so read this as a maker's comparison. The facts about other products come from their official pages and repositories, checked in September 2026.

Tool types

Which kind of tool do you need?

Most "best mouse sharing software" lists mix three different things. Decide which group you are in first; it removes most of the candidates.

PC to PC

Two computers on one desk

Two or more computers, each with its own screen, share one mouse and keyboard over the local network. Push the cursor off one screen edge and it appears on the next machine, usually with a shared clipboard and simple file transfer. This is the classic software KVM: Synergy, Deskflow, Input Leap, Barrier, Mouse Without Borders, ShareMouse, and OneMouse for Windows-to-Windows or Windows-to-Mac.

PC to phone or tablet

Control Android from the PC

You want to type and click on an Android phone or tablet without picking it up. There are two approaches. Mirroring tools such as scrcpy show the phone in a window on the PC. Edge-crossing tools move the cursor onto the phone's own screen as if it were another monitor; OneMouse is in this group, and older ADB-based utilities such as DeskDock and InputShare are too. Roundups rarely cover this category at all.

Ecosystem / vendor

Only within one brand's devices

Free features built into a platform that only work with that vendor's hardware or account: Apple Universal Control (Mac and iPad), Samsung Multi Control (Galaxy devices), and Logitech Flow (Logitech mice). If every device already qualifies, these are convenient. If one device falls outside the brand, they do not apply.

PC to PC and PC to Android · our product

OneMouse

A Windows 10/11 PC shares its mouse and keyboard with Android phones and tablets, other Windows PCs, and Apple Silicon Macs (macOS 13+) by crossing the screen edge, with file transfer and clipboard sync. Everything stays local: pairing uses a 6-digit code or QR code, and there is no account or server. Limits: Windows must be the host, no Linux, no iPhone or iPad, Macs need Apple Silicon and connect over LAN by default (Bluetooth for Mac is a beta option, off by default), and the Android Free tier has ads plus daily clipboard and file limits that a one-time Pro unlock removes.

PC to PC · paid

Synergy

Commercial software KVM from Symless for Windows, macOS, and Linux; any computer can be the server. Personal licenses are a one-time purchase and business licenses are per seat. Synergy 1 and Synergy 3 were both updated in June 2026. Main limitation: no Android, iOS, or ChromeOS client, although Symless says it plans to support them in the future.

PC to PC · free, open source

Deskflow

The open-source core that Synergy builds on: GPL-2.0, TLS on by default, and builds for Windows, macOS, Linux, and FreeBSD. It is the actively maintained project in the Barrier and Input Leap lineage, with v1.26.0 released in February 2026. Main limitation: no official Android client. A third-party Android 14+ client exists but has had no release since July 2025.

PC to PC · free, open source · archived

Input Leap

A fork of Barrier covering Windows, macOS, Linux, and BSD, including a Wayland build. The GitHub repository was archived in July 2026 and is read-only; its last release was v3.0.3 in June 2025, and former contributors point to Deskflow instead. It still runs where installed, but it will not receive security fixes.

PC to PC · free, open source · unmaintained

Barrier

The fork of Synergy 1.9 that many 2026 roundups still recommend. Its last release, v2.4.0, dates from November 2021, and that release page states that Barrier is no longer maintained and receives no security fixes. Its successor, Input Leap, was itself archived in 2026, so Deskflow is the live option in this family.

PC to PC · free, open source

Mouse Without Borders

Microsoft's Windows-only tool, now part of PowerToys (MIT). It links up to four Windows 10/11 PCs on the same network with a shared clipboard and single-file transfer up to 100 MB, and it received encryption updates in August 2026. Main limitation: Windows only. Android support is an open feature request, not a feature.

PC to PC · free tier and paid

ShareMouse

Windows and macOS software KVM from Bartels Media, updated to 7.0.27 in August 2026. ShareMouse Free covers two computers and two displays for personal, non-commercial use; Standard and Professional are one-time purchases with 12 months of updates. Main limitation: no Linux and no Android or iPhone/iPad, and the vendor says it has no plans for them.

Ecosystem · free software, needs hardware

Logitech Flow

Lets a Flow-enabled Logitech mouse move between two or three Windows and macOS computers on the same network through Logi Options+, with a compatible Logitech keyboard following it. Main limitation: it requires Logitech hardware with Easy-Switch, needs internet access for the initial setup, and does not support tablets or phones.

Ecosystem · free, built in

Apple Universal Control

Built into macOS 12.4+ and iPadOS 15.4+: one Mac controls up to two more Macs or iPads with one keyboard and mouse. Main limitation: only Macs and iPads from Apple's supported model lists, all signed in to the same Apple Account with two-factor authentication and within 10 metres. There is no Windows, iPhone, or Android endpoint.

Ecosystem · free, Galaxy only

Samsung Multi Control

Samsung's way of controlling a phone from a PC: a Galaxy Book (2021 or later), or a Windows 11 PC running Samsung's Multi Control app from the Microsoft Store, moves the cursor onto Galaxy phones and tablets with a shared clipboard and file drag-and-drop. Main limitation: Samsung lists only Galaxy devices on One UI 5.1 or later, and every device needs the same Samsung account plus Bluetooth and Wi-Fi.

PC to phone · free, open source

scrcpy

Genymobile's mirroring tool shows the Android screen, with audio, in a window on a Windows, macOS, or Linux host and forwards keyboard and mouse input; nothing is installed on the phone. v4.1 was released in July 2026. Main limitation: it is a mirror window, not edge crossing, and it needs USB debugging over a cable or ADB over Wi-Fi (OTG mode is USB only).

Pick by situation

Start from the devices on your desk.

Two Windows PCs on one desk: Mouse Without Borders is free, already inside PowerToys, and handles up to four Windows PCs. OneMouse also links two Windows PCs with two-way file, folder, and clipboard transfer, and can do it over Bluetooth when there is no router. ShareMouse Free covers two computers for personal use.
Windows PC + Android phone or tablet: OneMouse moves the cursor onto the phone over Wi-Fi or Bluetooth with no cable, no ADB, and no brand requirement. Samsung Multi Control fits if you have a Galaxy phone, a Galaxy Book or Windows 11 PC, and a Samsung account. If you would rather see the phone's screen in a window, use scrcpy (any brand, USB debugging) or Phone Link's Phone screen on the brands it supports.
Windows PC + Mac: OneMouse works when the Windows PC is the host and the Mac is Apple Silicon on macOS 13 or later, over LAN. If the Mac must be the controlling machine, or it is an Intel Mac, use Synergy (paid), Deskflow (free), or ShareMouse. Logitech Flow works if you already own a Flow-enabled Logitech mouse.
Mac + iPad: Apple Universal Control, built in and free. OneMouse does not support iPad or a Mac host.
Linux involved: OneMouse does not support Linux. Deskflow is the actively maintained free option for Windows, macOS, and Linux, and Synergy is the paid one with vendor support. Lan Mouse is a newer open-source alternative with Wayland support. Avoid Barrier and Input Leap for new setups; neither is maintained.

FAQ

Questions people ask before choosing.

Is there free mouse and keyboard sharing software?

Yes. Mouse Without Borders (Windows only, part of PowerToys), Deskflow (Windows, macOS, Linux; open source), and ShareMouse Free (two computers, personal use) cost nothing. The OneMouse Windows and Mac apps are free as well; the OneMouse Android app has a Free tier with ads and daily clipboard and file limits, and a one-time Pro unlock removes them.

Does mouse and keyboard sharing work without an internet connection?

Software KVMs such as OneMouse, Synergy, Deskflow, and Mouse Without Borders run over the local network and do not need internet access. OneMouse can also connect over Bluetooth with no router at all. Some vendor tools depend on an online account: Apple Universal Control requires an Apple Account, Samsung Multi Control a Samsung account, and Logitech Flow needs internet access for its initial setup.

Controlling an Android phone from a PC: is that a mirror window or a real cursor?

They are different things. Mirroring tools such as scrcpy, Vysor, and Phone Link show the phone screen in a window on the PC and you click inside that window. Edge-crossing tools such as OneMouse and Samsung Multi Control send the PC cursor onto the phone's own display, so the phone behaves like an extra monitor. OneMouse works by edge crossing and also offers an optional remote-control window.

Does OneMouse need an account or a server?

No. Devices pair locally with a 6-digit code or QR code (a PIN with SPAKE2 key exchange), and input, files, and clipboard data move directly between your own paired devices. There is nothing to sign in to and no relay server.

Can I share a mouse and keyboard over Bluetooth instead of Wi-Fi?

With OneMouse, Android devices and other Windows PCs can connect over Bluetooth instead of Wi-Fi; the Mac app connects over the local network by default (Bluetooth for Mac is a beta option, off by default). Bluetooth is slower than Wi-Fi, so large files are better sent over Wi-Fi. PC-to-PC software KVMs such as Synergy, Deskflow, Mouse Without Borders, and ShareMouse work over the network only. Apple Universal Control uses Bluetooth together with Wi-Fi and Handoff.

Mouse Without Borders or OneMouse?

Mouse Without Borders is free, ships inside Microsoft PowerToys, and links up to four Windows PCs with a shared clipboard and single-file transfers up to 100 MB. OneMouse also links Windows PCs and adds Android phones and tablets, Apple Silicon Macs, Bluetooth connections, and folder transfer between PCs. If every machine is Windows and PowerToys is already installed, Mouse Without Borders is enough; OneMouse fits when a phone, tablet, or Mac joins the desk.

Synergy or OneMouse?

Synergy is a paid software KVM for Windows, macOS, and Linux in which any computer can be the server. OneMouse requires a Windows host, does not support Linux, and its Windows and Mac apps are free. The main difference is Android: Synergy has no mobile client, while OneMouse controls Android phones and tablets over Wi-Fi or Bluetooth.

Does OneMouse support Linux, iPhone, or iPad?

No. OneMouse targets are Android, other Windows PCs, and Apple Silicon Macs running macOS 13 or later, always with a Windows 10/11 PC as the host. For Linux, use Deskflow or Synergy. For a Mac and an iPad, use Apple Universal Control.
