Are there analogues of "Trello" for my "requirements"?

Question

Task Management

I am looking for an analogue of Trello, because. I didn't like some of the features.
In general, I need a service where you can create a kanban board for free (I hope I put it right). That is, so that you can create columns, and each column has its own records.
0. Free service.
1. Column names can be set randomly
2. Actually, records between columns can be moved with the mouse cursor
3. You can get a link to the board and distribute it so that people can watch the project without registering on the site
4. Hide some columns from public access (not a mandatory requirement )
It doesn't seem like a big requirement, but basically he stumbled over the fact that you can't get a link to view the board for random people.
Of those that I liked, but did not fit the requirements:
* zenkit
* meistertask
