Welcome to Active DataComm's list of free downloadable software and online tools; from office suites to planetarium software, this list contains just some of our favorite free applications and tools. Many of the tools here are free and open-source, some are proprietary freeware, and others are proprietary commercial products, with free versions available for personal use.

Though we maintain this list, the links will take you directly to the third-party pages where each tool is available. As with any file you download from any website, it is important to scan any files you download from these sites with modern, current anti-virus software. Also, using any of these tools is at your own risk, of course, but we have indicated the applications that we believe should only be used by advanced users.
