Which do you use?
Who Should Choose What?
→ Choose Lucidchart if:
Your team collaborates on diagrams in real time, or you need integrations with Confluence, Google Workspace, and auto-layout for complex architecture diagrams. The team features justify the cost.
→ Choose diagrams.net if:
You need free, unlimited diagramming with no account required. diagrams.net is perfect for developers and IT professionals who create technical diagrams and want zero cost with maximum privacy.
→ Consider neither if:
For wireframing and product design, Figma or Whimsical are better fits. For mind maps specifically, Miro or MindMeister offer richer features. For code-as-diagrams, Mermaid.js is the developer-friendly option.

Frequently Asked Questions
Editor's Take
I used Lucidchart for years at work because the team needed real-time collaboration. When I went freelance, I switched to diagrams.net and honestly haven't missed Lucidchart once. The interface is dated, sure, but for making flowcharts and ERDs by myself, it does everything I need at zero cost. Save the Lucidchart budget for tools where the paid features actually matter for your workflow.
