I use, almost exclusively, the open-source version of ColdFusion (called Lucee).

It’s fantastic. And users don’t care what your stack is, a long as it woks.

Yes, Pud, I'm aware of Lucee. I still have CF running in one legacy app but it's been sunset and not being updated. 100% on customers not caring. They don't. Ever. The stack wars are purely for our own benefit. We trump our own trumpet or however that saying goes...

Now,

I have to diverge here, and say that I'm a fan since F-Company days (which was ColdFusion wasn't it?), and a customer of DistroKid (well, my own kid took over the subscription and I need to get another one now).

Is that the ColdFusion he's talking about? https://www.adobe.com/products/coldfusion-family.html

Seems to be alive.

It's not "dead", but rarely used for new projects if at all. A lot of legacy exists still (one of my businesses still runs it, from that period in time). Originally by Allaire, then sold to Macromedia which was later bought by Adobe.
