A cross-platform, low-latency control room for gaming. Toggle packet-friendly network tweaks, clear background interference, and flip it all back when you're done.
- Runs natively on Windows, macOS & Linux — one app, OS-aware tweaks.
- Animated glass UI with an intro splash, navy theme, and toast feedback.
- Built-in updater — a bar appears when a newer release lands on GitHub; one click downloads, swaps the binary, and relaunches.
- Honest about platforms — every tweak with a real equivalent works everywhere; the handful that are genuinely Windows-only stay visible but greyed.
- Setup wizard checks privileges and the renderer before launch.
| Tweak | Windows | macOS | Linux | Notes |
|---|---|---|---|---|
| Fast DNS (Cloudflare) | ✅ | ✅ | ✅ | netsh / networksetup / resolvectl |
| Flush DNS | ✅ | ✅ | ✅ | resolver cache clear |
| Kill bandwidth hogs | ✅ | ✅ | ✅ | closes OneDrive, Dropbox, Spotify… |
| Process priority boost | ✅ | ✅ | ✅ | High priority / renice |
| Reset network stack | ✅ | ✅ | ✅ | heavier reset for stubborn issues |
| Nagle's algorithm | ✅ | ✅ | — | macOS uses delayed_ack sysctl |
| TCP auto-tuning | ✅ | — | ✅ | Linux uses tcp_moderate_rcvbuf |
| Wi-Fi power saving | ✅ | — | ✅ | Linux uses iw … power_save |
| Delivery Optimization | ✅ | ✅ | — | macOS maps to Content Caching |
| Wi-Fi auto-scan | ✅ | — | — | no safe equivalent elsewhere |
| Network throttling index | ✅ | — | — | Windows-only OS subsystem |
| Game Bar / DVR | ✅ | — | — | Windows-only OS subsystem |
| Location tracking | ✅ | — | — | Windows-only registry consent |
Greyed (—) tweaks target OS subsystems that don't exist on that platform. They're shown but disabled — nothing fake or no-op.
Download the build for your OS from the latest release:
| OS | File | First launch |
|---|---|---|
| Windows | DelagR.exe |
Double-click. Approve the UAC prompt for tweaks. |
| macOS | DelagR-macos |
chmod +x DelagR-macos, then right-click → Open (first time only, to clear Gatekeeper). DelagR asks for your password only when a tweak needs it. |
| Linux | DelagR-linux |
chmod +x DelagR-linux && ./DelagR-linux. Privileged tweaks use pkexec (needs a polkit agent). |
DelagR checks GitHub on launch. When a newer release exists, a bar slides in at the top:
┌───────────────────────────────────────────────────────────┐
│ ↑ DelagR v2.2.0 is available [ Update now ] [ Later ] │
└───────────────────────────────────────────────────────────┘
Update now downloads the right asset for your OS, replaces the running binary, and relaunches — no manual steps.
# Windows (PowerShell)
./build_windows.ps1 # -> dist/DelagR.exe
# macOS
./build_macos.sh # -> dist/DelagR-macos
# Linux
./build_linux.sh # -> dist/DelagR-linuxPushes to main build all three via GitHub Actions. Running the Build DelagR workflow with a release_version (e.g. v2.1.0) publishes a release with all three binaries attached.
A small setup wizard verifies privileges and the renderer, then the main window opens via pywebview — EdgeChromium on Windows, Cocoa WebKit on macOS, QtWebEngine on Linux. Tweaks run through native commands (netsh/reg/powercfg, networksetup/sysctl/AssetCacheManagerUtil, resolvectl/iw/nmcli), elevating per-action via UAC, the macOS auth dialog, or pkexec.
