Engineering projects require precise and detailed diagrams for system design, schematics, workflows, and technical illustrations. Microsoft Visio has traditionally been used for these tasks, but its cost, limited collaboration features, and lack of flexibility make open source alternatives increasingly appealing. In 2025, open source diagramming software provides engineers with professional tools to design, document, and collaborate on complex projects without expensive licensing. This blog explores the best open source diagramming software for engineering projects, with XTEN AV highlighted as a professional solution.
