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.
Quick start
Desktop app (beta)
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.
Personal install (CLI)
npm install -g @bitkyc08/opencodex # Node 18+; the Bun runtime is bundled automatically
ocx start # proxy + dashboard on localhost:10100Use 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.
ChatGPT account pool
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.

Docker Compose
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. Initialize the data-plane token once through stdin and start the hub:
git clone https://github.com/lidge-jun/opencodex.git
cd opencodex
docker compose build
openssl rand -hex 32 | docker compose run --rm -T hub bun run docker/bootstrap-token.ts
docker compose up -d
curl --fail --silent http://127.0.0.1:10100/healthz
curl --fail --silent http://127.0.0.1:10100/readyzThe default host binding is 127.0.0.1:10100. Remote exposure requires explicit
OPENCODEX_BIND_ADDRESS=<LAN-or-Tailscale-IP> docker compose up -d; 0.0.0.0 opts into
all host interfaces. Restrict access with a firewall and an authenticated TLS/tailnet frontend.
The generated JSON stays untracked. The build context admits only .git/index and .git/HEAD — the
inventory git ls-files reads, about 1 MB rather than the full object store — and they are visible
only to the build-only manifest stage through a read-only mount, so no COPY includes .git. An existing host-generated manifest
is still accepted only after validation; otherwise the build generates one itself. The build rejects
stale manifests, missing or mismatched files, extra source files, and symlinks.
It checks every recorded SHA-256 against the build context and copied runtime files, including
package.json, bun.lock, and the specifically included scripts/model-metadata.source.json.
A remote Git context needs BuildKit to retain Git metadata. This Compose build fragment selects the remote snapshot and passes the required built-in argument:
services:
hub:
pull_policy: build
build:
context: https://github.com/lidge-jun/opencodex.git#main
dockerfile: Dockerfile
target: runtime
args:
BUILDKIT_CONTEXT_KEEP_GIT_DIR: "1"The token and mutable state stay in the ocx-state named volume; no credential is placed in the
image, Compose file, environment, or shell arguments. See the
Remote Hub deployment guide for provider
setup, authenticated acceptance checks, remote management, and rollback.

cd opencodex; bun install
bun run build:gui
bun run src/cli/index.ts startSource install runs the latest dev branch. Memory ownership
patches, runtime GC improvements, and unreleased fixes are available here before
they reach the npm package.
For agents
npm install -g @bitkyc08/opencodex
ocx start # or `ocx service`
ocx init # interactive setup: writes ~/.opencodex/config.json and wires Codexocx init never starts the proxy; start it first (or after — either order works, but headless
commands like ocx provider add and ocx combo set talk to the live proxy and exit nonzero
when it is unreachable). ocx status / ocx doctor / ocx health report the running state.
Agents installing or running opencodex: read
AGENTS_INSTALL.md. An interactiveocx startmay ask once whether to star this repository — that is the user's decision, never an agent's. The CLI suppresses the prompt for agent-driven runs and the API refuses them with403 agent_consent_required.
Supported platforms
| OS | Status | Service manager | Desktop app (beta) |
|---|---|---|---|
| macOS (arm64 / x64) | Fully supported | launchd | Universal .dmg |
| Linux (x64 / arm64) | Fully supported | systemd (user unit) | x86_64 .AppImage / .deb |

The CLI install requires Node 18+; the desktop app needs neither Node nor Bun. The Bun runtime is bundled on npm install — no separate
Bun install needed, no WSL needed on Windows. If npm blocked the bundled runtime's install scripts,
see the installation docs.
Highlights
-
Use any LLM with Codex, Claude Code, Claude Desktop, and Grok Build — 40+ providers out of the box, each keeping its own native UI.
-
Pool ChatGPT accounts — thread affinity, quota-aware auto-switching, cooldown and fail-closed auth handling.
Provider-policy note: Account pooling is for routing and operational resilience only; it does not guarantee protection from provider rate limits, enforcement, suspension, or other account actions. OpenCodex does not endorse using additional accounts to circumvent provider limits or sharing account credentials between people. You are responsible for complying with each provider's current terms. See the Codex Auth account-pool guidance and OpenAI's current Terms of Use.
-
Combos — one virtual model id with failover or weighted round-robin across providers. See the combo guide.
-
Sub-agents on any model — feature routed models in Codex's sub-agent picker, with v1/v2 surface control and fallback chains. See the sub-agent guide.
- Log in once, skip the API key — OAuth for xAI, Anthropic, and Kimi; or forward
codex login, paste a key, or use${ENV_VAR}references. - Web search & vision sidecars — non-OpenAI models get real web search and image understanding through a sidecar over your ChatGPT login.
- See what's happening — the dashboard shows providers, OAuth status, model selection, and a live request log with cache token counts.
- Clean exit, zero residue —
ocx stoprestores Codex to its original configuration. - Bounded memory ownership — every long-lived cache, ring buffer, and protocol-translation
store has a finite cap, byte budget, or active reconciliation. No unbounded
MaporSetsurvives a config reload.
Memory ownership details
OpenCodex tracks 36 categories of process-retained state. Each has a documented bound:
- 12 retained stores (request log, debug rings, image cache, model cache, vision descriptions, cursor blobs, responses continuation, etc.) are byte-accounted and evicted by the app-owned memory budget (default 256 MiB).
- 4 observed buffers (translator accumulators, image/OAuth/Grok tails) are monitored for in-flight byte pressure without eviction.
- 24 state-store registrations handle expiry sweeps (60 s interval) and config-generation reconciliation so stale provider/account keys are removed.
- Path and fingerprint memos (workspace metadata, hardened identities, installation salts, mode-hint capabilities) use insertion-order LRU caps (8–128 entries).
- Model-cache generation tombstones are deleted after reconciliation; a global generation increment prevents stale in-flight discoveries from repopulating removed providers.
- Lab event-id deduplication runs under a ledger lock from disk, with no process-level RAM index.
Run GET /api/system/memory (with the admin token) to inspect live retained bytes,
eviction counters, and watchdog samples.
Model routing
Target any configured provider and model with the provider/model syntax:
codex -m "anthropic/claude-opus-5" "Explain this stack trace"
codex -m "google/gemini-3-pro" "Write unit tests for auth.ts"
codex -m "ollama/llama3" "Refactor this function"Omit the provider/ prefix to use the default provider or auto-match by model name pattern.
Provider model ids containing / are exposed with inner slashes aliased to -; the raw
full-slash form keeps working too. Details: model routing docs.
Providers & adapters
OpenAI (ChatGPT login or API key), Anthropic, Google Gemini, xAI, Kimi, Azure OpenAI, Ollama
(local + Cloud), Cursor (experimental), and every OpenAI-compatible endpoint — plus DeepSeek,
Groq, OpenRouter, Together, Fireworks, Cerebras, Mistral, Hugging Face, NVIDIA NIM, MiniMax,
Qwen Cloud, Qoder Global and CN (official PAT + CLI), SiliconFlow, and more. Full list: ocx init or the
provider docs.
CLI
ocx init # interactive setup (writes config, wires Codex, offers the shim)
ocx start [--port 10100] [--socks5 [host:port] | --socks5-off] # SOCKS5 defaults to socks5://127.0.0.1:10808
ocx stop # stop + restore native Codex
ocx service [install|repair|restart|start|stop|status|uninstall|remove] # background service
ocx codex-shim install # start the proxy on demand whenever `codex` launches
ocx health [--json] # check immediate proxy liveness
ocx ready [--json] [--wait [--timeout <seconds>]] # check post-sync readiness
ocx status # is the proxy running?
ocx gui # open the web dashboard
ocx provider <...> # manage providers (list/add/edit/test/remove)
ocx account <...> # manage ChatGPT accounts & API-key pools
ocx combo <...> # manage failover / round-robin combos
ocx v2 <...> # multi-agent v1/v2 surface controls
ocx update [--tag preview] # update opencodexA start whose preferred port is busy stops and names the holder instead of moving to another port,
so it can never leave a second proxy running beside the first. Free the port, or name a different
one with --port. Full reference: CLI docs.
Health and readiness
GET /healthz reports immediate proxy liveness. The unauthenticated GET /readyz endpoint reports
post-sync readiness with the sanitized JSON identity {service, version, uptime, pid, port, status}.
It returns 200 when status is ready; pending and terminal failed return 503 with
Retry-After: 1.
ocx ready [--json] [--wait [--timeout <seconds>]] performs one probe by default. --wait polls
for up to 45 seconds by default, but exits immediately when it observes terminal failed;
--timeout <seconds> sets a 1–300 second limit, requires --wait, and accepts only positive integers. CLI --json output is
{ready, status, pid, port}, where status is ready, pending, failed, or unreachable.
| Exit | Result |
|---|---|
0 |
Ready |
1 |
Not ready: pending, failed, timeout, or unreachable |
64 |
Invalid arguments |
An older proxy without /readyz fails closed as unreachable with exit 1, while ocx health
remains compatible.
Autostart: service vs shim
Use the service (ocx service) for an always-on proxy that restarts on crash. Use the
shim (ocx codex-shim install) for lightweight, on-demand startup without a background
daemon. Remove them with ocx service uninstall / ocx codex-shim uninstall.
Uninstall
ocx uninstall # stop, remove service/shim, restore native Codex, clean up state
npm uninstall -g @bitkyc08/opencodexRemote access
By default opencodex binds to 127.0.0.1 and needs no extra authentication. Binding beyond
loopback ("hostname": "0.0.0.0") requires a bearer token — the proxy refuses to start
without OPENCODEX_API_AUTH_TOKEN, and every client request must carry it as
x-opencodex-api-key. Details: configuration reference.
Documentation
The public docs — install, providers, routing, combos, sub-agents, sidecars, integrations, and
the CLI/config/management-API references — are built from docs-site/ and
published to opencodex.me.
Maintainer source-of-truth notes live under structure/, contributor setup in
CONTRIBUTING.md, and security reporting in SECURITY.md.
Report undisclosed vulnerabilities privately through
GitHub private vulnerability reporting,
not a public issue.
That form is the only technical channel — there is no security email. Follow-ups stay in the
private report itself; a public issue may carry coordination only, never vulnerability details.
Acknowledging a report is not the same as triaging it, and no first-response target is promised.
Development
Source development requires the bun CLI on your PATH. This is separate from the published npm
package's bundled Bun runtime, which is used only by installed ocx commands.
