When I started working at Netatmo, one of the first need I had was to be able to know who is who and do what in the company. Surprisingly enough, I couldn’t find any simple tool to do that, as most solution are enormous paid intranets that were overkill. So I decided to make my own, using Python and Flask. It is not the best codebase ever, and I’ll admit it lacks in the support department, but it worked and was used for almost 10 years, so I am really proud of it :).
