Yes, there are easier dashboards to just install and use, but this is a pretty good article on how to configure for the use of Appsmith (which can be used for many other purposes).
Appsmith is an open source, low-code app builder that helps developers build internal apps like dashboards and admin panels easily and quickly. It’s a great choice for your dashboard, and reduces the time and complexity of traditional coding approaches.
