ShareMouse vs Synergy (2026): which should you pick?

Pick ShareMouse if

• Fits if you split work between a Windows PC and a Mac on the same desk
• Works for personal two-computer setups

Look elsewhere if

• Not for you if it is for a company, as free is personal use only
• Skip it if you use Linux or want a phone in the setup
• Tight if you have more than 2 computers or screens, since the free edition stops there
• Watch out: the vendor states no refund policy and points to the free demo, about 30 minutes at a time
• Watch out: no price was readable for Standard or Professional

Pick Synergy if

• Fits if you have a Windows PC, a Mac and a Linux machine on one desk
• Works for copying on one computer and pasting on the next

Look elsewhere if

• Not for you if you want to try it first at home, as personal licenses only have a 30-day money-back guarantee
• Skip it if your computers aren't on the same local network, because it only works across one
• Pricey if your company is paying, since that needs a Business license from $90 a seat each year
• Watch out: the $15 Lite plan has no TLS/SSL encryption or hotkeys, so you'd need Plus at $19
• Watch out: every computer still needs its own screen, and Business editions send a daily usage report

ShareMouse

• Prices could not be read: the shop sends buyers to a PayProGlobal checkout that this research could not open, so no price is recorded.
• The free edition is for personal use only; use in a company context, with more than two displays or with Standard or Professional features needs a paid license.
• The vendor states it has no refund policy and points to the free demo, which runs all features for about 30 minutes at a time.
• Each computer must have its own monitor and be on the same local network, and every display counts toward the limit, including a laptop's built-in screen.

Synergy

• Personal licenses have no free trial, only a 30-day money-back guarantee; the 14-day trial is for Business plans.
• Lite covers 3 computers and has no TLS/SSL encryption or hotkeys. Plus allows 5 computers and Max allows 15.
• All computers must be on the same local network and each needs its own screen, because Synergy does not share video.
• A Business license is required when a company pays for, reimburses or deploys Synergy, and Business editions send a daily usage report.

ShareMouse

One mouse and keyboard for several computers

Move the pointer to the monitor of another computer and mouse and keyboard input is sent to it over the local network, with no hardware switch.

Windows and Mac together

Works with any mix of Windows 10/11 and macOS computers, so a Mac can be controlled from a PC and the other way round.

Clipboard sharing and drag and drop

Formatted text or files copied on one computer can be pasted on another, and files can be dragged between machines. The vendor's shop table places some of these in paid editions.

Encrypted traffic

Network traffic can be password-protected and AES encrypted; the vendor says it never records or transmits your input anywhere.

Editions by computers and screens

Free and Standard cover 2 computers; Standard allows up to 4 screens, and Professional allows up to 9 computers and 16 screens.

Synergy

Shared keyboard and mouse

Move the pointer off the edge of one screen to control the next computer with the same keyboard, mouse or trackpad, without a hardware KVM switch or its switching delay.

Clipboard sharing

Copy text or an image on one computer, move the pointer to another and paste it there.

TLS/SSL encryption

Encrypts the keystrokes and clipboard data sent between computers over the local network. It is included from the Plus tier upward, not in Lite.

Hotkeys and key swapping

Shortcuts switch between computers or send keystrokes to another machine, and the Windows and Command keys can swap automatically when moving between Windows and Mac.

Auto-config and discovery

Synergy 3 has an interface rebuilt from the ground up with automatic configuration and discovery of computers, and a screen layout for arranging them.

Business controls

Business licenses add policy-based settings, centralized configuration, challenge-based offline activation for air-gapped networks and priority support.
