    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Goofy

    Goofy

    Desktop client for Facebook Messenger

    Goofy is a macOS client for Facebook Messenger.

Feel free to create issues on this repo for feature requests of any kind. However, some features may not be possible due to the way this application is working. Also, I don't want this to be a feature-bloated monster, but a slick and small app....
