RealVNC Viewer, now officially called RealVNC Connect Viewer, is the client app you install on the computer or phone you control from. It connects to remote machines running RealVNC Server, either through RealVNC’s cloud or directly over the network, and suits IT staff, help desks and home users who already use RealVNC Connect. The RealVNC Viewer download itself is free, but the product is shareware (conditionally free): free use is limited to a trial or the non-commercial Lite plan, and work use needs a paid plan.
The Viewer changed a lot in 2026. From version 8.4.0 you must sign in to a RealVNC account to use it, and connecting to third-party VNC servers such as TightVNC, TigerVNC or UltraVNC became a paid-plan feature. The older v7 app lives on as RealVNC Classic Viewer, but only Premium and Enterprise customers can download it, from the RealVNC Portal.

What it does
- Connects to RealVNC Server devices in your team through RealVNC’s cloud brokering. It tries a direct peer-to-peer path first and falls back to RealVNC’s relay.
- Direct connections by IP address or hostname to RealVNC Server on the LAN or over a VPN.
- End-to-end encryption, multi-factor authentication and SSO sign-in (Entra ID and Okta are documented) when connecting to RealVNC Server.
- File transfer, chat, remote printing and session recording within RealVNC Connect.
- One-time access codes, which in 8.5.0 refresh every two minutes and no longer require unattended access to be switched on.
- Third-party VNC server connections (paid plans only, unencrypted) to keep legacy VNC hosts in the same device list.
- Windows MSI deployment and policy templates (ADMX for Windows, plus macOS and Linux templates) to lock down settings.
How IT teams use it
Connect to a team device over the cloud
- Install the Viewer and sign in with your RealVNC account; the app keeps you signed in until you sign out.
- Devices that run RealVNC Server and joined your team appear in the device list.
- Double-click a device and authenticate with the credentials the server expects. By default that is usually the remote computer’s own user account (system authentication).
- Use the toolbar for file transfer, chat or full screen.
Direct connection on the LAN or over a VPN
- Make sure RealVNC Server on the target listens for direct connections (TCP 5900 by default) and the host firewall allows it.
- In the Viewer, type the IP address or hostname into the search bar at the top and press Enter.
- Authenticate as prompted.
Do not expose port 5900 to the internet. For off-site technicians, put the network behind WireGuard or OpenVPN, or use cloud connections, which need no inbound ports.
Roll the Viewer out to technicians
- Take the Windows MSI from the official download page.
- Deploy it silently with your usual tool, for example:
msiexec /i RealVNC-Connect-Viewer-8.5.0-Windows-en.msi /qn - Import the Viewer ADMX templates into Group Policy to preset or lock options. RealVNC also documents building a pre-configured SSO MSI.
Install and first run
- Windows: an MSI installer, also offered as a ZIP archive. Installing it needs admin rights.
- macOS: one universal package for Intel and Apple silicon.
- Linux: DEB and RPM packages for x64; Raspberry Pi builds exist as well.
- Mobile: “RealVNC Viewer: Remote Desktop” in the App Store and Google Play.
- Account: you must stay signed in to use the Connect Viewer. Plan this for shared technician PCs.
- Gotchas: the Viewer is only half the setup, because every remote machine needs RealVNC Server (or the all-in-one RealVNC Connect app). Pointing it at a third-party VNC server on a free plan will not work. Cloud connections rely on outbound internet access, so proxies may need configuring from the sign-in screen.
Limitations
- Account sign-in is mandatory from 8.4.0; there is no anonymous use any more.
- The free Lite plan is strictly non-commercial. RealVNC treats connecting to a computer at your workplace as commercial use.
- Third-party VNC servers need a paid plan, and those connections are not encrypted.
- Offline licensing and fully on-premises use require Classic Viewer, which only higher-tier customers can download.
- Feature depth depends on the plan you are on, so check before you promise users session recording or SSO.
RealVNC Viewer vs alternatives
| Tool | Licence | Notes |
|---|---|---|
| RealVNC Viewer | Shareware | Polished, cloud brokering, account required |
| TightVNC | Free, GPL | Classic Windows VNC server and viewer, no account |
| TigerVNC | Free, GPL | Cross-platform viewer, strong on Linux servers |
| UltraVNC | Free, GPL | Windows VNC with file transfer and repeater support |
If you only need to reach existing VNC servers without an account, one of the free open-source viewers above is the practical choice.
FAQ
Is RealVNC Viewer free?
The download is free. Ongoing free use is possible with a trial or the non-commercial Lite plan; business use and features such as third-party VNC connections require a paid plan.
Can I use RealVNC Viewer without an account?
Not from version 8.4.0. RealVNC Connect Viewer requires you to sign in and stay signed in. Classic Viewer (v7), which covers direct-only and offline scenarios, is only offered to Premium and Enterprise customers.
Is there RealVNC Viewer for Mac?
Yes. RealVNC publishes a universal macOS package for Intel and Apple silicon Macs.
Where can I get RealVNC Viewer 7?
Version 7 is now called RealVNC Classic Viewer. RealVNC keeps supporting it, but standalone installers are only in the RealVNC Portal for Premium and Enterprise teams.
How do I connect RealVNC Viewer to a Raspberry Pi?
Run RealVNC Server (or the RealVNC Connect app) on the Pi and join it to your team, then pick it from the device list. If the Pi uses a different VNC server, such as WayVNC, the Viewer treats it as a third-party server, which needs a paid plan.
RealVNC vs TightVNC: which should I use?
RealVNC adds encryption, cloud connectivity and account-based control but needs a plan for work use. TightVNC is free and open source, simple on Windows LANs, and should be wrapped in a VPN or SSH tunnel.
What does “too many authentication failures” mean?
The VNC server has temporarily blocked your address after repeated wrong passwords. Wait for the block to expire or restart the server service, then check the credentials. RealVNC Server controls this with its BlacklistThreshold and BlacklistTimeout parameters.
