There is another home automation software, which is not as popular as Home Assistant, openHAB (https://www.openhab.org/). openHAB, just like HA, has many integrations, you can have a look on the website. The Github is https://github.com/openhab.
In the company I was working for we were trying to create a building automation software and we were between HA and openHAB. We finally chose openHAB because it is written in Java and we could find easier help from Java developers in-house rather than Python where HA is written.
OpenHAB seems to be the choice if you're doing something commercial and want German Engineering And Stability.
But one thing it isn't is user friendly.
I'm not an IoT novice (I did that for a living for half a deacade) neither a programming novice (Java for a living since -99). Still I couldn't wrap my head around the OpenHAB way of doing things.
And I didn't even want anything complicated, just wanted my Hue lights to turn on when I pressed a button.
