diagrams.net (formerly draw.io) is free online diagram software. You can use it as a flowchart maker, network diagram software, to create UML online, as an ER diagram tool, to design database schema, to build BPMN online, as a circuit diagram maker, and more. draw.io can import .vsdx, Gliffy™, and Lucidchart™ files.
I have used Lucidcharts in the past and found that to be very useful. But with Draw.io, you can have a desktop application and can import various templates to draw.
