Aspia

About

Aspia is a free and open-source application for remote computer management, primarily designed for Windows platforms. It offers a comprehensive suite of features including Desktop Sharing, Screen Sharing, Unattended Access, and Support for Multiple Monitors. Users praise its ease of installation and use, particularly for LAN or VPN environments, and its ability to handle different screen sizes/resolutions. While some users position it as an excellent alternative to RDP or VNC, others consider it a strong, free replacement for paid solutions like TeamViewer or AnyDesk, noting its lightweight server, ability to connect to hosts by ID, and NAT traversal via an aspia-relay server. The software is constantly evolving and includes an address book with grouping. Its open-source nature and lack of direct connection requirement (using aspia-relay and aspia-router) are key differentiators. Aspia is available for Windows and its source code is hosted on GitHub.
