Bandwidth Governor
I ran Claude Code so hard and so regularly that my internet started having issues. So I built this. A free Windows app that rate-limits bandwidth per-app or globally using Windows QoS policies — so Claude can keep coding while your Zoom calls, streaming, and browsing stay smooth.
Claude Code Integration
Auto-detect your upload speed and cap Claude-related processes (node, git, ssh, scp) to a percentage you choose.
Per-App Limiting
Throttle specific executables — OneDrive, git, node.exe — without slowing down everything else.
One-Click Presets
Upload-only or balanced profiles. Strict, medium, or light. Pick one and go.
Live Bandwidth Monitor
Real-time upload/download Mbps display across all network adapters.
Built-in Speed Test
Test your connection speed using Cloudflare endpoints without leaving the app.
System Tray
Runs in background. Quick toggle on/off from tray. Starts with Windows if you want.
How it works
Bandwidth Governor creates Windows QoS (Quality of Service) policies via PowerShell. These are OS-level throttles — not proxy hacks or VPN tricks. They work immediately, persist across app restarts, and can target specific executables or apply globally.
Requires Windows 10/11 and Administrator privileges. No installation — just download the portable .exe and run it.
Licensed under BSL 1.1 — converts to Apache 2.0 after 4 years per release.
80 tests. 100% code coverage. Built with Electron.
