This is a great list, though it's not that helpful for comparing them with each other. There is also https://www.starter.place/ which includes more information about what features are included in each one.

What's still missing is some kind of aggregated review service or something for these. From the outside it's still very difficult to tell the difference between "well-maintained, production-ready thing that has been used by hundreds of real businesses" and "some rando's app they threw on github / are trying to sell".

There is such a huge difference in quality/maturity for many of these and that is literally all you are paying for. Still a tricky market to navigate.
