This Magento 2 module allows you to provide a custom shipping method in backend only, frontend only or both. With the Scheduler feature you can manage the availability automatically.
I was surprised by this nice extension and installed it but after installing and configuring I found out that this extension isn't working.
It doesn't hide other shipping extensions and in my case it does hide itself in the frontend but also in the backend. Might be doing something wrong but I don't know what since it's all straight forward.
