from their website [1]:
Navicat Premium is a database development tool that allows you to simultaneously connect to MySQL, MariaDB, SQL Server, Oracle, PostgreSQL, and SQLite databases from a single application. Compatible with cloud databases like Amazon RDS, Amazon Aurora, Amazon Redshift, SQL Azure, Oracle Cloud and Google Cloud. You can quickly and easily build, manage and maintain your databases.
Of course, I just use DataGrip now, but if you want Navicat see if Premium Essentials is still around as it may work for you.
For my own work use I really have no choice but DataGrip, it's the only database utility that supports DB2 for i, Microsoft SQL Server and PostgreSQL - all of which we use heavily at work. But also being a heavy user of other JetBrains products (IntelliJ, ReSharper, PyCharm) having a familiar interface is a huge positive over Navicat since all of my keyboard shortcuts work the same and I only have two different (VS vs IntelliJ-based IDE) ways I have to remember how to do code snippets instead of three.
You might find Vertabelo [1] useful and possible replacement of LucidChart & Visio for db modeling.
*with more paid advance features, but hey, if you need those, it's worth it.
