ThinRDP was an HTML5 remote desktop gateway from Cybele Software that let users open Windows desktops in a web browser without installing an RDP client. If you searched for ThinRDP, the product you want today is Thinfinity: ThinRDP was renamed Thinfinity Remote Desktop Server in October 2014, and Thinfinity Remote Desktop has since been replaced by Thinfinity Workspace, the current product line aimed at IT teams that need browser-based access to desktops, applications and internal systems.
The idea has not changed since the ThinRDP days: one Windows server inside your network publishes RDP and other connections through HTTPS, and users connect from Chrome, Edge, Firefox or Safari on any device. What has grown is everything around it, from access profiles and multi-factor sign-in to VDI management and a Zero Trust approach that avoids exposing internal hosts to the Internet.

What it does
- Opens RDP sessions in a plain HTML5 browser, with no plug-in or RDP client on the user’s device.
- Supports more than RDP: the Enterprise edition also handles VNC, SSH, Telnet and 3270/5250 terminal connections, plus web applications through its Web Application Gateway.
- Publishes individual Windows applications as well as full desktops.
- Groups connections into Access Profiles that are assigned to users and groups, so each person sees only what they are allowed to open.
- Uses outbound-only reverse connections in its Zero Trust design, so internal hosts do not need inbound ports open to the Internet.
- Manages VDI pools on VMware, Hyper-V and Proxmox, with a cloud manager for autoscaling (Workspace 8 and later).
- Offers a dedicated Thinfinity Desktop Client for users who connect all day and prefer an app to a browser tab (introduced in version 8).
- Shows the state of gateways, brokers, agents and live sessions in a Monitoring Module added in 8.5.
How IT teams use it
Publish an RDP desktop to browser users
- Install Thinfinity Workspace on a Windows machine that can reach the target hosts.
- Sign in to the Workspace portal as an administrator and click +New Profile.
- Choose Desktop, then RDP, then This PC or Another PC and enter the target IP address.
- Choose from the drop-down list how credentials for this resource are handled, name the profile and click Done.
- Click Commit to save. The profile icon now appears for assigned users; clicking it opens the session in the browser.
Replace an old ThinRDP install
- List what the old ThinRDP server published: hosts, users and any shortcuts or URLs your staff use.
- Stand up Thinfinity Workspace on a supported, patched Windows Server instead of upgrading in place on an old OS.
- Recreate the connections as Access Profiles and test them with a pilot group.
- Point your DNS name and certificate to the new server, then switch off the ThinRDP service. Cybele’s customer care team handles upgrade paths for existing licences.
Give contractors access without a VPN
- Create a group for contractors and assign only the profiles they need.
- Turn on multi-factor or single sign-on through your identity provider.
- Use the reverse-connection gateway so internal RDP hosts stay unreachable from the Internet.
Install and first run
Server. Thinfinity runs on Windows. The gateway component is listed for 64-bit Windows 8 and later and Windows Server up to 2022 on the official requirements page; remote desktop targets can be any Windows version with RDP enabled. Install with an administrator account and allow the HTTPS listener through Windows Defender Firewall. Replace the default certificate with your own before giving users the URL.
Users. Any HTML5-capable browser works, including Chrome, Edge, Firefox and Safari, on desktops, tablets and phones. Nothing needs to be installed unless you choose the Desktop Client.
Common gotchas. RDP must be enabled on every target host and reachable from the Thinfinity server (TCP 3389 inside the LAN). Multi-user sessions on Windows Server still need Microsoft RDS client access licences; Thinfinity does not replace them.
Limitations
- ThinRDP itself is no longer developed or sold under that name; old ThinRDP builds should not be exposed to the Internet.
- Commercial only: there is no free edition for production use.
- The server side is Windows-only.
- Browser sessions depend on the browser for keyboard shortcuts, clipboard and multi-monitor behaviour, which is less complete than a native RDP client.
- Workspace is a full platform (broker, gateway, agents); for one or two servers it can be more than you need.
Thinfinity Remote Desktop vs alternatives
Apache Guacamole is the free, open-source way to reach RDP, VNC and SSH from a browser; it runs on Linux and takes more manual setup. TSplus Remote Access turns one Windows server into a multi-user application server with its own HTML5 portal and is aimed at smaller businesses. Thinfinity sits higher: it brokers access to many hosts and VDI pools with Zero Trust features and central monitoring.
