The picker is stock Claude Code. The brain behind it isn't.
Pick a provider and go — same workflow, different brain.
Opus answers, then hands the task to a GPT-5.6 Sol subagent.
Sol drives the session and calls a Kimi K3 subagent.
opencodex is a lightweight local proxy that translates Codex's Responses API into whatever your provider speaks — streaming, tool calls, reasoning tokens, images, in both directions. Use Claude, Gemini, Grok, GLM, DeepSeek, Kimi, Qwen, Ollama, or any other LLM with Codex, Claude Code, Claude Desktop, and Grok Build. It can also manage a ChatGPT account pool for Codex auth: add accounts, refresh their quotas in the dashboard, and let new sessions auto-route to the lowest-usage healthy account while existing threads stay pinned to the account that started them.
npm install -g @bitkyc08/opencodex # Node 18+; the Bun runtime is bundled automatically
ocx start # proxy + dashboard on localhost:10100
Use ocx service to run it in the background.
Open http://localhost:10100 and configure everything in the web dashboard — add providers
(40+ built-ins, or any OpenAI-compatible endpoint), pick models, manage accounts. ocx gui
re-opens the dashboard at any time.
The desktop app is the same proxy and dashboard in a native window, with a tray and bundled ocx.
It attaches to a proxy that is already running, or starts its bundled one, and the dashboard stays
on the proxy port (http://localhost:10100 unless you configured another). Pick the file for your
platform from the latest release:
| Platform | File | Notes |
|---|---|---|
| macOS 13+ (Apple Silicon and Intel) | OpenCodex-<version>-macos.dmg |
Universal build, signed with a Developer ID and notarized |
| Windows (x64) | OpenCodex-<version>-windows-x64.msi |
Not code-signed yet: SmartScreen asks once, choose More info → Run anyway |
| Linux (x86_64) | OpenCodex-<version>-linux-x86_64.AppImage or -linux-amd64.deb |
The tray needs an AppIndicator-capable desktop |
Every file has a .sha256 next to it on the release page. On macOS 14+ the app also ships a
WidgetKit extension that shows proxy status, today's usage and provider quotas; the snapshot model
it renders lives in app/ (MenuBarCore). To build the app yourself, run
bun install && bun run build:gui at the repository root, then in desktop/ run
bun install && bun run prepare-sidecar && bun run prepare-widget && bun run build:local on macOS,
or bun install && bun run prepare-sidecar && bun run build:local on Windows and Linux (the widget
step needs macOS). The Desktop App guide and the
macOS Menu Bar App guide cover first launch, and
AGENTS_INSTALL.md lists everything written to disk.
opencodex can also manage a ChatGPT account pool for Codex auth. Add multiple ChatGPT / Codex accounts, refresh their 5h / weekly / 30d quota in the dashboard. Under quota routing, new sessions can use the lowest-usage healthy account; round-robin and fill-first use their own policies. Existing Codex threads normally retain affinity to the account that started them, so long SSH, tmux, or mobile-connected sessions do not jump accounts mid-conversation — but quota re-evaluation, failover, account exclusion, affinity expiry, or 401/403 and 429 recovery can rebind them. Give the accounts a selection order when one of them — usually your Codex Desktop login — should only be reached for once the others are drained.

The repository ships a digest-pinned, non-root Compose build. The build generates and verifies the canonical compatibility manifest from the selected Git snapshot. A local clone needs Git and Docker Compose; a remote Git context needs Docker Compose. Neither path needs host Bun or a preparation step. Initial
