draw.io vs Lucidchart

draw.io

• UML, ERD, network and flowchart diagrams at no cost
• Teams whose data rules require files to stay in their own storage
• Diagramming offline on Windows, macOS or Linux
• Documentation kept in Confluence, Google Drive or GitHub

Lucidchart

• Documenting processes as flowcharts and process maps
• Engineers drawing UML, ERD and cloud architecture diagrams
• Teams that embed diagrams in Confluence, Jira or Microsoft 365
• Org charts built from imported data

draw.io

• There is no hosted workspace or account: every diagram is a file kept in the storage you pick, so sharing depends on that storage.
• Real-time co-editing needs the file to be in Google Drive, OneDrive or Dropbox, or the diagram to be in draw.io for Confluence.
• No native mobile apps are listed; the docs suggest adding the web editor to a phone's home screen instead.
• Using draw.io inside Confluence or Jira needs the vendor's Atlassian Marketplace apps, which are licensed separately from the free editor.

Lucidchart

• The Free plan is limited to 3 editable documents and 75 shapes per document.
• The iOS app requires a Team or Enterprise subscription; Free and Individual accounts are pointed to the browser version instead.
• Revision history, the developer platform and the Microsoft 365, Confluence and Jira integrations start at Team; SAML is Enterprise only.
• The pricing page shows only annual-billing rates. Its FAQ says monthly billing is available but gives no monthly price.

draw.io

Shape libraries for technical diagrams

Libraries and templates cover process flows, org charts, floor plans, network infrastructure, UML, entity relationship models, circuit and rack diagrams, and infographics.

Storage you choose

Diagrams are saved to Google Drive, OneDrive, Dropbox, GitHub, GitLab, the browser or the local device. The online editor does not store diagram data on the vendor's servers.

Offline desktop app and self-hosting

A stand-alone desktop app for Windows, macOS and Linux works with no internet connection, and the editor can be deployed in a self-hosted Docker container.

Co-editing with shared cursors

People editing the same diagram see each other's changes in real time when the file is stored in Google Drive, OneDrive or Dropbox, or in draw.io for Confluence.

Diagrams generated from text

The editor builds diagrams from Mermaid code, CSV spreadsheet data or SQL code, and an AI tool can generate a diagram from a written description.

Import, export and embedding

Files from other diagramming tools can be dropped in and edited, and diagrams export to SVG, PNG or PDF or embed as interactive viewers in docs, wikis and web pages.

Lucidchart

Shape libraries for technical diagrams

Libraries cover flowcharts, process maps, org charts, UML, ER and network diagrams, plus AWS, Azure and GCP shapes. Premium libraries need a paid plan.

Lucid AI

Text prompts generate diagram content on the canvas, and AI can refine a prompt or summarize a document. Lucid AI is listed on every plan, including Free.

Data linking

Connect a diagram to Google Sheets, Excel or CSV data to build visuals from the source, then use conditional formatting to highlight patterns in it.

Diagram from markup

UML markup generates a sequence diagram from text, and ERD markup and diagram-as-code options let technical users edit the source instead of dragging shapes.

Collaboration and versioning

Several people can edit a diagram at once and leave comments. Revision history with versioning is added on the Team plan.

Visio import and export

Paid plans open and export Microsoft Visio files, and the Android app can import and view VDX, VSD, VSDM and VSDX formats.
