Also interested in other tools. I don't mind working on the command line but Lens (and OpenLens later on) has been my tool of choice for keeping an eye and managing on our K8s stuff.
We have been working on an alternative project for several months, and will open its source on April 22nd. I truly believe this project will keep open source forever, it will be a project backed by CNCF Foundation, hope you can give a try after we open its source.
