building git ; need suggestion

Hello list,

Greetings !!!

I'm building a git repo on a dedicated server; hence need some kind guidelines from you.

[1] the server will have different git repo with branches [2] there will be a web-based GUI which must be flexible to show just a specific branch of a repo based on user authentication [3] the web-based GUI should also have the flexibility to show a single repo based on the authentication [4] the web-based GUI should have an admin account to supervise and configure all repos along with their branches [3] there must be a control mechanism in the repo/web based GUI which have ACL on branches i.e. some specific users should see some specific/ or just a branch and able to commit there only.

based on the above scenario could anyone suggest the best available solution ? There are many like gitolike/github etc…. but don't know whig one has much finer granular control/ACL/web-based GUI…

Thanks in advanced for your kind response.
