    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.

    Graph NotebookAmazon GameLift Unity

    Graph NotebookAmazon GameLift Unity

    Access GameLift resources and integrate GameLift into your Unity game

    The Amazon GameLift Plugin for Unity contains libraries and native UI that makes it easier to access GameLift resources and integrate GameLift into your Unity game. You can use the GameLift Unity Plugin to access GameLift APIs and deploy AWS CloudFormation templates for common gaming scenarios. Auth Only, this scenario creates a game backend service that performs only player authentication and no game server capability. It creates a Cognito user pool to store player authentication information, as well as an API gateway REST endpoint backed up AWS Lambda handlers to start a game and view game connection information. The Lambda handler always returns a 501 Error (Unimplemented). Single-Region Fleet, this scenario creates a game backend service with a single GameLift fleet. After player authenticates and starts a game (with a POST request to /start_game), a AWS Lambda handler searches for an existing viable game session with an open player slot on the fleet.

    Grasscutter

    Grasscutter

    A server software reimplementation for a certain anime game

    Grasscutter is an open-source Java server reimplementation for a certain anime-style online game, created for private server emulation and research. It uses Java 17, MongoDB, and Gradle, and it has an ecosystem that includes documentation, a launcher, plugins, and community tooling. The project allows users to run a compatible server environment for specific supported game client versions, but it is not actively maintained in the same way it once was. Current documentation warns that version matching matters and that support is limited, especially beyond the older supported release range. Grasscutter is most relevant to developers interested in reverse engineering, server emulation, game protocol research, and modding communities. Because it interacts with proprietary game clients and services, it should be used only in lawful, authorized, and non-commercial contexts.

    Gamer's Proxy

    Gamer's Proxy

    Proxy for games that emulates network conditions like ping and lag.

    Ever played a competitive game with a friend in which one of you hosted the server on their own machine? Ever thought that it's unfair that one person's ping is zero and the other one's is 80? This is an open-source program that can emulate constant ping, ping spikes and packet losses. Download, extract wherever you want, launch the executable and read the instructions that are conveniently placed in the main window of the program. This program allows gamers to fake their ping and packet loss. Only games which allow direct IP connections are supported - this program will not emulate the game server and will not advertise itself on any master server of any game. The idea is this: game client -> proxy -> game server Demonstration video: http://youtu.be/2VWNhmfD1Qk
