Discord RAM Limiter

Discord RAM Limiter is a small Windows desktop app that monitors Discord memory usage and can trim Discord's working set while it runs in the background.

The app uses the native Windows SetProcessWorkingSetSize(process.Handle, -1, -1) call on detected Discord processes when the limiter is enabled.

Antivirus Note

This app is a small unsigned Windows executable. Some antivirus scanners may flag unsigned apps heuristically, especially when they inspect running processes. The release build is not packed or obfuscated, and the source code is available in this repository.

You do not need to disable your antivirus to use this app. If you are unsure, do not run the release build; build the app from source and compare it with the release checksum.

Requirements

To run the release build:

• Windows 10 or newer.
• .NET Desktop Runtime, if using the framework-dependent release.

To build from source:

• Windows 10 or newer.
• .NET 10 SDK with Windows Desktop support.

Build From Source

Clone or download the repository, then run:

dotnet restore .\DiscordRamLimiter.sln
dotnet build .\DiscordRamLimiter.sln

Run From Source

dotnet run --project .\DiscordRamLimiter\DiscordRamLimiter.csproj

Create A Local Release Build

This creates a small framework-dependent release folder:

dotnet publish .\DiscordRamLimiter\DiscordRamLimiter.csproj -c Release --self-contained false -p:DebugType=None -p:DebugSymbols=false -o .\publish\DiscordRamLimiter-github-release

The output contains:

DiscordRamLimiter.exe
DiscordRamLimiter.dll
DiscordRamLimiter.deps.json
DiscordRamLimiter.runtimeconfig.json
