Onscryn vs
Kasm Workspaces.
Kasm Workspaces is a platform for streaming workspaces to a browser, and it can connect to Windows servers over RDP. Onscryn is built specifically around publishing Windows applications. They overlap when the job is Windows in a browser, and part ways on how much you run and how Windows apps are treated.
| Onscryn | Kasm Workspaces | |
|---|---|---|
| How Windows is reached | A host agent, with the app captured on the host and streamed to a browser | Per Kasm's documentation, over RDP through its Connection Proxy service |
| Windows setups described | Windows hosts you enroll, in your network or a cloud you choose | Static Windows servers, auto-scaled Windows servers, or sitting in front of Microsoft RDS, Azure Virtual Desktop or Windows 365 |
| Focus | Windows applications, with desktops as an option (plan-dependent) | A workspace platform where Windows is one of the integrations its documentation covers |
| Licensing | Windows and your own software still need licences. We go through it with you | Per Kasm's documentation, you need appropriate Microsoft licences, which may include Windows Server, RDS CALs and Office. Kasm does not provide Microsoft licensing support |
| Multi-session desktops | Per-session Windows accounts on a shared host | Per Kasm's documentation, Windows 10 and 11 multi-session images are not supported outside Azure, so deployments elsewhere need one VM per user |
| Data controls | Clipboard and file policy at the broker, watermark, recording | Check their documentation. Kasm describes adding DLP and isolation in front of existing Windows deployments |
| Automation | UI-tree workflows and a Copilot (preview) built in | Check their documentation |
Choose Kasm Workspaces if
- You want one platform to stream a mix of workspaces to a browser, and Windows is only part of it.
- You want to put its isolation and policy in front of an RDS, Azure Virtual Desktop or Windows 365 deployment you already have.
- You are comfortable running and scaling the platform yourself.
Choose Onscryn if
- Your goal is specifically to publish Windows applications to people in a browser.
- You want per-session accounts on shared hosts rather than one VM per user.
- You want clipboard and file policy, a watermark, recording and automation in one product.
- You want your own branding and domain on the front door.
Two routes to Windows
Kasm's documentation describes a connection proxy that reaches Windows apps and desktops over RDP, with options ranging from a fixed set of Windows servers to autoscaled servers in a cloud provider, and an option to sit in front of an existing Microsoft deployment. That is flexible, and it means Windows is reached through RDP like other remote desktop tools.
Onscryn puts an agent on the Windows host, captures the application on the host, and streams it to the browser, with each person in their own Windows account. The difference matters most when many people share the same legacy app.
Licensing
Kasm's documentation says you need appropriate Microsoft licences for what you access, and that it does not provide licensing support. The same applies to Onscryn: Windows and your own software still need licences, and we would rather work through them with you than pretend otherwise.
