Lucidchart

Lucidchart is a web-based diagramming application developed by Lucid Software. Since its launch in 2010, it provides a platform for creating, editing, and sharing diagrams and visualizations. Users can produce flowcharts, organizational charts, ER and data models, network diagrams, UML diagrams, mind maps, and process maps using a browser-based editor with drag-and-drop functionality and a library of shapes and templates.

Its real-time collaboration features allow multiple users to edit and comment simultaneously, with revision history and role-based access controls. Lucidchart supports data linking to external sources, extensive templates, and import/export in common formats such as PNG, PDF, SVG, and Visio-compatible files. The service includes diagram automation tools, shape libraries, and presentation modes.

It is offered as a cloud service with browser access and companion mobile apps for iOS and Android. It integrates with Google Workspace, Microsoft 365, Slack, Jira and Confluence, Salesforce, and other enterprise tools, with APIs and automation via Zapier or webhooks.

Lucidchart operates on a freemium model, with a free tier and paid subscriptions for individuals, teams, and enterprises. Paid plans unlock advanced collaboration, admin controls, additional templates and shapes, data linking, and enhanced security features such as single sign-on and access management.

The product has become a widely used diagramming solution in business, education, and IT contexts, competing with legacy tools such as Microsoft Visio. It is generally praised for its ease of use, real-time collaboration, and broad integration options, though critics have noted pricing and occasional performance issues with very large diagrams.
