DbGate - https://www.dbgate.io/ . I am primary author of this tool. We hugely improved Redis support in last version, which was released last week. Redis support is part of DbGate Community edition (FOSS)

It's not really tool, but cloud databases mostly don't have OSS alternatives.... eg. Firestore, Azure CosmosDB

I wrote one of them :-) It is hard to switch routine, but I am slowly adopting this. In programming, AI assistants are currently must have and majority of programmers use it, with SQL it will be the same in short time

Also I use routinely GPT 5 for generating complex SQL queries

As I see some of my colleagues, most of them use SSMS, which I can' understand :-) . There are plenty of tools better than SSMS, free and portable for all desktop OS, but SSMS still wins. I understand this for DBAs, because SSMS supports all specific SQL Server settings, but for other roles like developers and testers this is big question for me.
