Onscryn vs
Apache Guacamole.

Apache Guacamole is a free, open-source gateway that lets you reach remote desktops from a browser using RDP, VNC or SSH. Onscryn is a commercial platform for publishing Windows apps to a browser. Guacamole is a building block; Onscryn is a finished product built on a different approach.

Choose Guacamole if

  • You want a free, open-source gateway and have people to deploy, secure and maintain it.
  • Your need is browser access to machines over RDP, VNC or SSH rather than managed per-app publishing.
  • You want to build around an API and own every piece.

Choose Onscryn if

  • You want a finished product for publishing Windows apps, not a toolkit.
  • You want per-session Windows accounts, clipboard and file policy, a watermark and recording without assembling them.
  • You want workflow automation and a Copilot working on the same sessions.
  • You need vendor support and a roadmap behind it.

Free is not the same as cheap

The software costs nothing, but deploying, hardening, scaling and supporting it takes people. Whether that is cheaper than a commercial platform depends on how much of that you already do and how much the gaps in controls and recording would cost you to fill.

Different problems

Guacamole is aimed at connecting a browser to a remote machine. Onscryn is aimed at delivering specific Windows applications to many people with policy, isolation and an audit trail. For some teams the first is enough. For others, the second is the point.

Questions.

It overlaps on browser access to Windows, but it is a gateway you build on, not a managed application-delivery platform.
