    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.

    Free offline PDF toolkit for Windows - merge, split, watermark, lock

    PDFGeek does the everyday PDF jobs on your own machine, with none of the limits the web tools impose.

The online alternatives cap you and then ask for money: 25 files per merge, three tasks an hour, a subscription to unlock batch mode. PDFGeek has no caps to lift, because your documents never leave your computer in the first place. Available as a per-user installer that needs no admin rights, or as a single portable executable you can run from a USB stick. No bundled offers, no telemetry, no account. 100% free, no Pro tier, free to use at home and at work. Built on .NET 8 and Avalonia. Requires Windows 10 or later, 64-bit.
