OpenCodex

A 4.7MB portable, bring-your-own-model desktop workbench for AI coding. Open a folder — the main area is a real terminal — split it and run multiple Claude Code / Codex CLIs in parallel. No bundled keys, no server; point it at any OpenAI/Anthropic-compatible endpoint. Tauri 2 + React, reuses the system WebView (no 200MB Electron).
