Launching ChatGPT with per-app proxy settings: Local Route Launcher now supports Windows
Description and use
Windows users can now launch ChatGPT through a per‑app proxy using Local Route Launcher, preserving system proxy settings.
Problem
Users need to run the ChatGPT desktop app through an HTTP proxy without altering system-wide proxy or DNS settings.
Outcome
Windows users can now run ChatGPT through a per‑app proxy using Local Route Launcher, preserving system proxy settings and providing diagnostics.
Workflow
- 1. Keep an authorized HTTP proxy running and note its host and port.
- 2. Fully quit any running ChatGPT instance.
- 3. Open Local Route Launcher (Windows installer includes .NET runtime).
- 4. Launcher searches for a compatible ChatGPT installation; optionally select ChatGPT.exe manually.
- 5. Launch ChatGPT through the launcher; system tray controls allow launch, close, and status checks.
- 6. Verify proxy reachability and TCP connections via local diagnostics.
Evidence
Local Route Launcher is a small open‑source utility for launching a compatible ChatGPT desktop app with an existing HTTP proxy, without changing system proxy or DNS settings.
Version 1.2.0 adds a Windows x64 installer
Keep an HTTP proxy you are authorized to use running, save its host and port, then fully quit ChatGPT and reopen it through the launcher.
Targets Windows 10 22H2 / Windows 11 x64 and macOS 13+ on Apple Silicon. A detectable Electron-based ChatGPT installation is required.
Connection checks are snapshots, not proof that all traffic follows the proxy settings; voice, WebRTC and UDP may behave differently.
