Diagram and whiteboard resources
A short, hand-picked list of outside sites we find useful alongside SketchFlow: references for the diagram types our templates use, communities where people share boards and templates, and directories for finding free tools. We are not affiliated with any of them. For the sites that list AltFTool itself, see the AltFTool backlinks directory.
