The best thing about the site is that it's free and doesn't require any signup or account creation on the platform. Also, it's extremely simple to use and includes a Docs tab to go through the specifics of ER diagram syntax. Review collected by and hosted on G2.com.
I can't think of a con for this site as it is designed to do a specific task unlike Lucidchart and it's good at its job. Review collected by and hosted on G2.com.
