3 Best Open Source Alternatives to TSplus

Updated July 2026

TSplus earns its place by getting legacy Windows software in front of users fast: a web portal, HTML5 access in the browser, published apps, and session controls without standing up the full Microsoft Remote Desktop Services stack. The friction starts when that remote-access layer becomes core infrastructure but stays a closed product whose security, MFA, monitoring, and scale are parceled out across editions and paid add-ons. Open source alternatives hand you an inspectable gateway or remote-desktop stack instead, with direct control over authentication and network placement. None is a drop-in clone of the all-in-one console, so you assemble the pieces you actually use rather than paying for the whole bundle up front.

RustDesk is an open-source remote desktop application for accessing and controlling machines across Windows, macOS, Linux, and Android. Designed as an alternative to TeamViewer, it works out of the box with no configuration required and gives you full control of your data.

  • Remote desktop access and control
  • Peer connections with direct or relayed routing
  • Audio, clipboard, input, and video handling
  • File copy and paste between systems

MeshCentral is a full computer management website for remote monitoring and management. You run your own web server, create device groups, install an agent on each computer, and manage machines on a local network or anywhere on the Internet from a browser.

  • Run your own web server for remote computer management
  • Agent-based device enrollment into device groups
  • Web-based remote desktop sessions
  • Browser terminal access and file management

Apache Guacamole is an HTML5 web application that provides access to your desktop using remote desktop protocols. It is built to serve as a browser-based client for remote access, so you can connect without installing a native desktop app on the machine you are using.

  • HTML5 browser access to remote desktops
  • Supports the VNC, RDP, and SSH protocols
  • Clientless: no plugins or client software needed
  • Runs under servlet containers like Tomcat or Jetty

Our picks

Open source splits what TSplus bundles, so pick by the access pattern you depend on most.

Browser-based remote desktop gateway: Apache Guacamole Apache Guacamole is the closest match to TSplus browser access: a clientless HTML5 gateway that reaches desktops over RDP, VNC, and SSH from any browser, with no plugin to install on the device you connect from. An Apache Software Foundation project, it deploys as a .war file under a servlet container like Tomcat or Jetty, so the gateway and every connected desktop stay on infrastructure you run.

Full remote desktop control: RustDesk RustDesk gives full remote control of Windows, macOS, Linux, and Android machines, with audio, clipboard, keyboard and mouse input, and file copy-and-paste between systems. Connections go peer-to-peer where a direct route exists and fall back to a relay otherwise, and you can self-host both the rendezvous and relay server rather than route through a vendor. It works out of the box with no configuration.

Web-based fleet management: MeshCentral MeshCentral runs as your own web server for remote monitoring and management, enrolling machines by agent into device groups you administer from a browser over a local network or the internet. It includes web-based remote desktop, terminal, and file management and is licensed under Apache 2.0. Choose it when ongoing management of many machines matters more than published-app delivery.

Switching from TSplus to open source

The mistake to avoid is treating TSplus as one product to clone. It bundles remote sessions, application publishing, browser access, gateway behavior, user mapping, and an admin console into a single commercial surface, and open source rarely packages all of that together in one place. Decide which part is actually critical - full desktops, individual published apps, browser access for contractors, or an internal help-desk tool - because the replacement usually splits those roles across a gateway, a session protocol, an identity provider, and separate monitoring.

The real loss when you leave is polish around the all-in-one experience. Moving off TSplus means more manual configuration and more responsibility for testing printing, clipboard, drive redirection, file transfer, MFA, and load distribution yourself. A browser gateway such as Apache Guacamole handles standard sessions well from any device but can feel different for graphics-heavy apps, while a tool like RustDesk gives full remote control of a machine rather than the seamless single-app publishing TSplus is known for. Plan for user retraining and a longer validation cycle than a simple client swap.

Migration begins with an inventory, not an export, because no TSplus configuration converts cleanly into another system. Document your servers, published applications, user and group assignments, gateway URLs, certificates, MFA settings, and printer mappings, then rebuild the access rules in the new stack by hand. The applications and user data usually stay where they are; it is the shortcuts, portal links, and device-redirection rules that need cleanup. Run a pilot in parallel, move DNS only after testing, and keep the old endpoint reachable until rollback is no longer a risk.

Frequently asked questions

What should I replace in TSplus first?+

Start with the role your users touch most. For some teams that is the browser portal, for others it is a set of published apps, full remote desktops, or contractor access through a gateway. Replacing everything at once multiplies risk, since each feature fails differently. Build a small pilot around one workflow, validate login, printing, file movement, and session timeout, then expand from there rather than cutting over the whole environment at once.

Can open source publish a single application instead of a full desktop?+

This is the hardest part of TSplus to reproduce. The tools here are strongest at full desktops and full remote control: Apache Guacamole serves entire desktop sessions in the browser, and RustDesk gives complete control of a machine. Seamless single-app publishing, where the underlying desktop is hidden, is where open source differs most, so if users rely on it, test that exact workflow early rather than assuming parity.

Is browser-based access realistic without TSplus?+

Yes, and Apache Guacamole is the clearest example: a clientless HTML5 gateway that reaches desktops over RDP, VNC, and SSH from any browser with no plugin installed. Treat it as its own architecture decision, though, with TLS termination, authentication, and logging that fit your security model. Browser clients are convenient for unmanaged devices but can limit keyboard shortcuts, audio, and file transfer, so test the exact browsers your users bring.

Where do MFA and login policy move after TSplus?+

They usually shift from the TSplus layer to your identity provider, gateway, or reverse proxy, which changes where prompts appear and how account recovery works. Confirm support for the factors you require, the enrollment process, remembered devices, and lockout behavior. Also check whether reconnecting to an existing session bypasses any prompt, because remote-access systems often differ in how they treat resumed sessions.

Do printers, clipboard, and file transfer still work?+

They can, but these are the features most likely to generate support tickets after a migration. RustDesk handles clipboard and file copy-and-paste between systems directly, while printer redirection depends on drivers, host policy, and the remote protocol in use. Build a test matrix for local printers, label printers, PDF output, copy-paste, uploads, downloads, and mapped drives before telling users the new system is equivalent.

Does the licensing cost really drop to zero?+

You remove the TSplus subscription and add-on charges, but the replacement is not free to run. Budget for server capacity, gateway hosting, monitoring, backups, security patching, and administrator time, plus any paid support you want around an open source stack. The honest comparison is total operating cost over a year against what TSplus editions and add-ons were costing, not the purchase price of the software alone.

Will one gateway keep up with many simultaneous sessions?+

Performance depends on the session protocol, gateway overhead, graphics load, storage latency, and how many users share each host, so never size it from a one-user test. Simulate peak concurrency with your heaviest applications and include printing or file transfer if those are common. Watch CPU, memory, disk queue, and reconnect times; scaling often means adding hosts rather than one larger gateway.
