draw.io

Description

draw.io (branded as Diagrams.net) is a full-featured diagramming solution that operates entirely in-browser without requiring logins or subscriptions. The tool offers an extensive library of shapes and templates for creating technical diagrams (network architectures, UML), business visuals (org charts, SWOT analysis), and creative wireframes. Files save directly to cloud storage (Google Drive, OneDrive) or locally, with optional team collaboration features. Despite its professional capabilities, the interface remains intuitive with drag-and-drop functionality, layer management, and export options to PNG/SVG/PDF. Unique among diagram tools, it maintains 100% free access to all features with no paywalls, making it ideal for students, engineers, and businesses needing reliable diagramming without vendor lock-in.
