This library detects user's browser (e.g. Chrome), device (e.g. Mobile), operation system (e.g. MacOS) and browser engine (e.g. Blink).

Have you ever sent by mistake emails from developer machine to production users? Unfortunately we did. We don't want this mistake to happen again so we wrote a package which takes care of it for us. Each time we send a message, script checks if recipients' email is on the white list. If so, then e-mail will be send to the user. If not then it will be send to our account. This allows us to safely test the high functionalities, such as the newsletter, on the production database.
Do you have a problem with selecting colors in your application? You definitely should check Coolors. It's a simple tool for generating random palettes of colors.
