Free flowcharting software alternatives
Unless you are one of those people who uses flowcharting software on a regular basis, it is hard to justify spending money on Visio, SmartDraw, or CorelDraw. So I set out to find some free flowcharting software alternatives.
You will need to register to begin drawing and must have a Flash plug-in installed in your browser.
draw.io is online diagram software / flowchart maker, built around Google Drive. It is a free tool to draw flowcharts, org charts, wireframes, UML, mind maps and more, then save them to your Google Drive. It uses the Google Drive Real Time collaboration functionality, so multiple users can work on the same diagram simultaneously.
ArgoUML is an open source UML modeling tool and includes support for all standard UML 1.4 diagrams. It runs on any Java platform and is available in ten languages.
Although these free solutions may not have all of the bells and whistles that the paid software offer, they will suffice the needs of most people.
