Quick verdict
Synergy (Symless) and HelloControlDesk both share a keyboard and pointer across computers. Synergy (Symless) is suited to a desk that includes Linux or needs its stated automatic setup, automatic discovery, and shared clipboard for text and images.
HelloControlDesk is suited to a Mac-and-Windows desk on one local network when the published plan details, a licence covering up to five machines, and token-based authentication without an account stored on the device match the requirement. For a broader selection framework, start with this guide to choosing software for one keyboard and mouse.
The comparison below uses public-product facts recorded in the validated sheets. It is not a performance test, and it does not infer details that those sheets do not state.
Comparison table

| Setup | Automatic configuration and automatic discovery are stated | Server and client work in either Mac-to-PC direction; client placement is stated for four screen sides |
| Clipboard | Shared clipboard, including text and images | Shared clipboard between machines |
| Multi-monitor information | Non communiqué | Multi-monitor configurations on both server and client sides |
| Connection protection | TLS/SSL is stated; local TLS is indicated for higher editions | TLS traffic encryption and licence-token authentication; no account credential is stored on the device |
| Network scope | Non communiqué | Same local network only, by Wi-Fi or Ethernet |
| Support | Non communiqué | Email support in the monthly plan; priority support in the annual plan |
| Hosting information | Non communiqué | Data hosted in the European Union is stated |

“Non communiqué” means that the validated sheet does not state the detail. It is not a conclusion about whether a capability exists.
Which differences matter for a multi-computer desk?
The first question is the operating-system mix. The validated Synergy (Symless) sheet lists Windows, macOS, and Linux. The HelloControlDesk sheet lists Mac and Windows and does not mention Linux or BSD. A desk with a Linux machine therefore has a stated platform requirement that HelloControlDesk does not claim to meet.
The second question is how the desk is arranged. Both products are described as moving control between computers through the cursor. HelloControlDesk also states placement on four screen sides and multi-monitor support on both the server and client sides. For either product, the practical check is whether the declared arrangement corresponds to the physical screens and the operating systems in use.
The third question is recovery after a normal desk interruption. HelloControlDesk states automatic reconnection after server sleep or a network interruption. The validated Synergy (Symless) sheet does not communicate an equivalent reconnection detail, so this comparison does not make one.
Pricing and plan information
For Synergy (Symless), the public pages recorded in the validated sheet did not communicate pricing. That does not mean there is no paid offer; it means this article does not have a published price to compare. The same sheet says that local TLS encryption is available in higher editions.
HelloControlDesk publishes a monthly plan at 14.90 EUR excluding VAT per month and an annual plan at 99.90 EUR excluding VAT per year. The monthly plan states server and client software for macOS and Windows, up to five machines, four screen positions, shared clipboard, multi-monitor support, TLS, a token, automatic reconnection, and email support. The annual plan states the same plan content, updates, and priority support. VAT is added at payment. Read the published plan details before choosing a subscription.
The figures were recorded from HelloControlDesk's pricing page dated October 2, 2026. They are plan descriptions, not a comparison with an undisclosed Synergy (Symless) price.
For whom Synergy (Symless) is the better fit
Synergy (Symless) is the fit described by its validated sheet when a desk includes Windows, macOS, and Linux. Its stated automatic configuration and automatic discovery can also matter where the setup calls for those functions. The same sheet lists shared clipboard support for text and images, plus keyboard, mouse, and trackpad sharing.
Its TLS/SSL capability is listed, with local TLS indicated for higher editions. Because the validated public information does not communicate pricing, support, hosting, or the exact scope of those editions, those points should be confirmed directly on the relevant public page before a purchase decision.
For whom HelloControlDesk is the better fit
HelloControlDesk is the fit described by its validated sheet for a mixed Mac-and-Windows desk on the same local network. One licence covers up to five machines, and the published monthly and annual plans list the same product capabilities rather than paid feature options.
It also fits a setup that needs a stated token-based connection with no account credential stored on the device, automatic reconnection after sleep or a network interruption, and multi-monitor support on both sides of the connection. It is not the stated fit for a Linux or BSD machine, for a desk that spans separate local networks, or for someone looking for a free plan.
