How to visualize the existing repository on the site only in php?

Question

PHP

There are several sites. All have GIT repositories, but in different folders (somewhere in the root, somewhere in the modules).
There is a desire to see a page with a tree of commits / branches on the site (as in github, bitucket).
GitLab is not suitable because there is no way to install Rubi.
HOWEVER, there is PHP.
Those. you just need a visualization page (on html + css + js based on php) of the GIT commit / branches tree with the ability to specify an arbitrary folder in which the repository lives , without the functionality of pullrequest, issue, wiki, etc. Only a tree.
