Out of curiosity what web server are they running?
Apache I believe
You could setup HAProxy in front of two apache servers with the same information on each. Set it up to pull updates from something like GitLab (or a selfhosted GIT server) and have any changes published through that. Have them talk back to a MySQL cluster. If you want to go fully fault tolerant, setup a HAProxy cluster with Keepalived running. Of course none of this really matters if there is a single physical host.

The customer standardizes on windows but the software is cross-platform.
But super slow and cumbersome on Windows
Both MySQL and PHP famously are dogs on Windows. -

Nope. But maybe it should be in some form.
Definitely. But that's not a factor in the current discussion.

For MySQL HA, the "go to" solution is generally Galera.
It's similar licensing to MySQL so a good match there, and is specifically the primary MySQL application layer HA product out there. I've used this in some pretty demanding environments (over 35K concurrent users.)

Is this active:active load balancing or active:passive/standby?

You don’t recommend Percona right?

It looks like Galera is an integrated part of MariaDB since v10.1, a few years back. Maybe that would be another option.

MariaDB is what is installed anymore when you do a yum/dnf install mysql anyway. Unless you have the specific repository for MySQL.

Both MySQL and PHP famously are dogs on Windows.I don't think that's true anymore. I haven't run any benchmarks on the same hardware but I think speed was brought up to parity with MySQL 5.5 by Oracle. And PHP after Microsoft started to work with Zend so around PHP 5.4 or so. Linux will probably always have the upper hand since that is the huge majority of installations and it would be my preference as well.

One example (real-life example), i have two production web servers set up. One on Windows and one Linux. They both use Apache, MariaDB, etc... The Windows one is (no exaggeration here) at least 5x - 10x slower in all aspects.

Active - Active, but we are talking about FT here, not LB.

I've not used it much.

Nearly all of us only run MariaDB, it's where the more serious development has gone. MySQL is mostly just used as an alias for MariaDB.

@scottalanmiller Yeah both of my webservers use mariadb for example
