- Use app.getPreferredSystemLanguages() for reliable OS language detection instead of relying solely on app.getLocale() which returns Chromium's internal locale (was returning zh-CN on pt-BR systems) - Support both Squirrel (%LOCALAPPDATA%) and WiX/MSI (Program Files) install directories when checking if app runs from expected location - Extract matchLocaleTag helper for cleaner language resolution logic - Add getAllExpectedInstallRoots to enumerate all valid install paths

✨ Why Gemini Nexus?
When using AI-powered IDEs and coding tools, have you ever run into these problems?
- 😫 Single account quota runs out quickly, requiring frequent manual switching
- 🔄 Managing multiple Google/Claude accounts is cumbersome
- 📊 Don't know how much quota or tokens you've consumed
- 🔌 Need a reliable local API proxy that speaks OpenAI/Anthropic protocols
- 🔍 Can't see what's actually being sent/received by the proxy
Gemini Nexus solves all of these. It's a professional Electron desktop application that acts as an intelligent gateway between your development tools and Google Gemini / Claude AI:
- ✅ Unlimited Account Pool — Add any number of Google Gemini & Claude accounts
- ✅ Smart Auto-Switching — Automatically rotates to the next available account when quota is low or rate-limited
- ✅ Real-time Usage Analytics — SaaS-grade dashboard with area charts, trend indicators, and model distribution
- ✅ Full Proxy Observability — Live traffic monitor, request replay, and model capabilities inspector
- ✅ OpenAI & Anthropic Compatible — Drop-in replacement proxy for Cursor, Windsurf, OpenCode, and any OpenAI-compatible tool
- ✅ Secure by Default — AES-256-GCM encryption with OS-native credential management
