<h3>TightVNC: Lightweight, GPL Remote Desktop for Windows and Older Unix Systems</h3>
<p>TightVNC is an open-source VNC-compatible remote desktop application designed for efficient screen sharing and remote control. The current 2.x branch focuses on Windows (runs on Windows XP and later) with installers for 64-bit and 32-bit systems and GPL-licensed source code available for download. Older 1.3.x releases provide broader support for Unix-like systems and legacy Windows versions.</p>
<h3>Key Features and Performance</h3>
<ul>
  <li><em>Efficient compression:</em> Tight encoding reduces bandwidth usage, making TightVNC suitable for low-bandwidth and high-latency connections.</li>
  <li><em>Remote control:</em> Full keyboard and mouse control of remote desktops for troubleshooting, administration, and remote work.</li>
  <li><em>File transfer:</em> Built-in file transfer between client and server simplifies exchanging documents and configuration files during sessions.</li>
  <li><em>Java and native viewers:</em> Multiple viewer options including Java viewer for browser-based access and native Windows viewers for better performance.</li>
  <li><em>Source availability:</em> GPL v2 source code download enables auditing, customization, and integration in open-source environments.</li>
</ul>
<h3>Security and Licensing</h3>
<p>TightVNC is distributed under the GNU General Public License (GPL) v2, allowing free use, distribution, and modification under open-source terms. A commercial license is available for organizations that need to incorporate TightVNC code into proprietary products. Users should plan network-level protections (VPN, SSH tunneling, or platform firewalls) when exposing VNC services to untrusted networks.</p>
<h3>Download Options and Version Information</h3>
<ul>
  <li><em>Latest 2.x Windows installers:</em> Separate 64-bit and 32-bit MSI installers are provided for the 2.8.87 release.</li>
  <li><em>GPL source:</em> Full C++ source archive available for developers who need to build or modify the software.</li>
  <li><em>Legacy builds:</em> Older 1.3.10 releases remain available for compatibility with legacy Windows and Unix-like systems.</li>
</ul>
<h3>Advanced Tools and Ecosystem</h3>
<p>The TightVNC project ecosystem includes complementary tools such as MightyViewer, a multi-VNC viewer for Windows that offers address books, live previews, multi-monitor support, and tabbed management for monitoring many remote desktops simultaneously. MightyViewer is available as a separate free download and is useful for administrators and classrooms.</p>
<h3>Who Should Use TightVNC</h3>
<ol>
  <li>System administrators and IT support teams who need a lightweight, scriptable VNC server and viewer for remote troubleshooting on Windows machines.</li>
  <li>Developers and organizations that require open-source VNC code under GPL v2 or a commercial license for proprietary use.</li>
  <li>Users operating on constrained networks who benefit from TightVNC�s bandwidth-optimizing encodings.</li>
</ol>
