Their freemium model fooled me, it is indeed open-source

Not open source.

Edit: sike, it is

I meant the first stabile release, my bad.

I didn’t know about it before you told me. It looks nice but I haven’t tried it yet so I don’t have an opinion on it.

Mainly no breaking changes. In the past I had to manually fix it on my server a few times.

Can’t wait for the stable release next year.
