diagrams.net is a free, open-source diagram editor with Lucidchart's core capabilities: flowcharts, UML, wireframes, and network diagrams from a huge shape library, saving to Google Drive, OneDrive, or locally. It runs in the browser or as a desktop app, with collaboration via shared files and no account required.
Excalidraw's real-time collaboration and hand-drawn style make it the fastest free diagramming tool for brainstorming, architecture sketches, and whiteboard-style charts. Shareable links open live rooms without accounts, and its library of community shapes extends it far beyond basic flowcharts.
Mermaid turns simple text into flowcharts, sequence diagrams, Gantt charts, and more — rendered in GitHub, Notion, and thousands of docs tools. For developers and technical writers, it replaces Lucidchart's diagramming with versionable, reviewable code, which is often better for documentation workflows.
Google Drawings creates flowcharts, org charts, and wireframes with standard shapes, connectors, and real-time collaboration, saving directly to Drive and embedding in Docs and Slides. It lacks Lucidchart's depth but covers everyday diagramming with zero cost and zero learning curve.
LibreOffice Draw is a full-featured desktop vector and diagram editor with flowcharts, org charts, and technical drawings, exporting to PDF, SVG, and more. For offline work and documents that must stay on-premises, it is a complete free Lucidchart alternative.
