Kasm Technologies Releases KasmVNC v0.9.3 Open Source VNC Server Software


KasmVNC v0.9.3 has been released by Kasm Technologies. KasmVNC is an open source web-native rendering technology that streams desktop, application, and web containers to the browser. The v0.9.3 release includes improvements to performance, security, and usability. KasmVNC provides streaming support for Workspaces container images. While the term VNC appears in the name, it is not intended to be RFB compliant and has different goals than other VNC projects:

  • Web-based – Intended to provide a remote desktop that is accessible via the internet. It includes a web server and a websocket server. Simply run it and navigate to the URL of your desktop on the port you specify.
  • Cybersecurity – According to the RFB specification (VNC), the password field is limited to 8 characters. KasmVNC uses HTTPS with HTTP Basic Auth by default and disables the legacy VNC authentication method for added security.
  • Simplicity – Because it is web-native and agentless, it is simple to deploy and configure.

Additional features that are new to this release include:

  • GPU Support in collaboration with VirtualGL.
  • Arm Support in collaboration with Arm.
  • Webp/JPEG image compression for better bandwidth & CPU usage.
  • Full screen video detection for improved playback performance.
  • Seamless Binary clipboard support for text, images, and formatted text (Chromium browsers).
  • Data Loss Prevention features – Key stroke logging, Clipboard logging, Max clipboard transfer size, Min time between clipboard operations required, Keyboard input rate limit.
  • Deb packages for Debian, Ubuntu, and Kali Linux & RPM packages for CentOS, Oracle, OpenSUSE, Fedora.
  • Relative cursor and cursor lock support (game pointer mode).
  • IME support for languages with extended characters.
  • Enhanced mobile support.

The open source VNC Server code KasmVNC is available directly on GITHUB. This code is supplemented by the open-source Kasm Workspaces images, which are available directly through Kasm’s Docker Verified Publisher images on DockerHub in Technical Collaboration with Docker.

“We are proud of our open source release of KasmVNC, especially the performance, usability, DLP and clipboard/character input enhancements,” said Matt McClaskey, Kasm Technologies CTO, “I am even more excited for our next release, which will cement KasmVNC as the modern, open source leader in remote desktop server solutions.”
