ความเห็นบรรณาธิการ

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 ฟีเจอร์ actually matter for your workflow.
