One reason to stay away from commercial Plugins is that you might be f**ed when they raise prices:
Years ago, I chose the Before-After-Slider from Themefic (like here: https://www.franzgraf.de/blog/2024/discovering-the-bosensteiner-almpfad/ ).
Back then for 19$ / year.
Now we are at 39$ / year.
Yes, the plugin now can do more – more stuff that I simply do not need. Well … Don’t get me wrong: I’m totally fine to pay for some service – but doubling the price for stuff that I just don’t need.
