Claudexor

Website

Claudexor is a local-first control plane for the AI coding agents you already pay for. It runs Codex CLI, Claude Code, Cursor CLI, OpenCode, Antigravity CLI, and raw API adapters behind one typed interface: a chat of turns where read-only questions resume the vendor's own native session, write turns land as inspectable patches or complete file manifests, races pit harnesses against each other with cross-family review, and every claim — cost, quota, web evidence, auth route — is a typed fact you can audit, never a vibe.

Compared to driving a bare Codex or Claude Code session, Claudexor adds the layer the vendors do not ship: best-of-N races with independent reviewers and arbitration; honest budget/quota accounting (unknown cost is never $0); deterministic gates and protected paths; and — since 2.1 — credential profiles: named Antigravity/Claude/Codex/Cursor subscription bindings side by side, each with Claudexor-scoped state and platform-declared credential custody. Live subscription-quota tracking — and the opt-in policy that rotates a spent account out of the way on typed vendor limits — covers the harnesses with a vendor quota source (Antigravity, Claude, and Codex). Cursor's internal dashboard supplies dated monetary resources, not an execution-quota verdict. Everything runs on your machine, files are the source of truth, and there is no telemetry.

Current status: v4.4.0. See "Stability at 2.0" below for what is a stable contract and what remains experimental; retired verbs and mode ids hard-error with the new spelling instead of silently aliasing.

Claudexor also runs as the exact-pinned delegated execution layer inside Ouroboros, a persistent self-developing agent. Ouroboros owns its tasks, memory, review, and final integration. Claudexor runs the connected coding harnesses and returns durable execution evidence. See Ouroboros in action.

Embedding callers can also make a single model request through a managed Codex subscription, using the same account as Agents. The caller supplies its own system prompt and tools and executes those tools itself. This is a typed engine operation, not a public OpenAI-compatible server or a second agent loop. Model catalogs and context limits are account-specific; subscription access does not guarantee zero incremental charges or enable provider-paid credits. See model operations for the transport, retention and unsupported-parameter contract.

Thanks to Praxis Relay and CLIProxyAPI for prior work exploring subscription-backed model transports. They informed this design; neither runs as an embedded relay or owns credentials in this integration.

If you use Claudexor — or you are an agent whose human does — a star is the one-click way to say it works.

Prerequisites

• Node.js >= 24.15 (the daemon, CLI, and every surface run on Node)
• pnpm (via corepack: corepack enable pnpm)
• Git for Git-backed worktrees, candidate envelopes, and source-control delivery. Explicit directory execution supports direct work and selected-input copies without Git; Doctor reports Git availability, and the app's Workspace Git check explains whether a Git-backed shape is admitted.
• At least one logged-in vendor CLI — codex, claude, cursor-agent (or Cursor’s agent), opencode, or agy (Antigravity, for a Gemini subscription) — OR a provider API key (adapters accept OPENAI_API_KEY, ANTHROPIC_API_KEY, ... as fallbacks; the raw-API route needs only a key). Log in through Claudexor, not the bare vendor CLI — see Install And Login
• macOS for the desktop app; the CLI/daemon also run on Linux

Install

CLI + daemon from npm (installs the claudexor and claudexord bins):

npm install -g claudexor
claudexor doctor

You can also build from source — see Quickstart below.

On a Mac, the app is the easiest way in — it ships as a signed and notarized DMG, so it installs like any ordinary Mac app, with no Gatekeeper warnings:

1. Download Claudexor-<version>.dmg from Releases.
2. Drag Claudexor.app into Applications.
3. Open it. The app starts its bundled Claudexor engine, then onboarding checks the external Git and harness route needed by the work you select.

The app bundles its own daemon runtime and starts it on launch; installing the Claudexor CLI is only needed for terminal use. Git and vendor harnesses remain separate capabilities checked before a run starts. (The v1.0.0 DMG was unsigned — if you kept it, either upgrade or approve it via System Settings → Privacy & Security → Open Anyway.)

Host integrations may install one vendor CLI into Claudexor's managed local toolchain with claudexor harness install <harness> --target local --yes --json; a host may bind that explicit unattended authorization to the user's Connect action. Npm recipes install exact selected versions under ~/.claudexor/node; Codex resolves latest once by default; --release-tested explicitly selects the separately tested baseline instead of that lookup (a runnable managed copy at or above it is kept; installing it still needs the npm registry), and an unavailable registry refuses instead of falling back. Cursor remains unpinned, so its JSON receipt records the downloaded installer's SHA-256 and byte length. Every successful executed receipt also records the absolute installed launcher and its verified version; a zero-exit installer without that postcondition is a typed failure. On Windows, Codex and Claude use the npm package's declared native or Node entrypoint. Doctor, login and runs share that selection, including ordinary user npm prefixes on PATH. The receipt identifies the vendor entrypoint; launch it through Claudexor so Node entrypoints retain their interpreter and arguments. Custom batch programs are not treated as standard npm wrappers. Omitting --target preserves the disclosed remote-host flow, its prefix and its exit-code contract; the install lease and the post-install proof are part of the unattended local contract and do not apply there.

Remote SSH

The macOS app can run a thread on a Linux or macOS SSH host while keeping the UI local. In Settings → Connections, pick a concrete alias from ~/.ssh/config or create one in-app — the form appends a plain Host block to ~/.ssh/config (after a timestamped backup), never a key or password. Connect it, then choose a saved folder or Browse on <host>… from the project picker. The thread is permanently bound to that host and folder; changing either creates a new draft.

Claudexor uses the system /usr/bin/ssh, so existing keys, ssh-agent, known_hosts, MFA and ProxyJump remain OpenSSH's responsibility. On first connection the app verifies and installs a signed, no-sudo runtime under ~/.claudexor/remote/, then reaches its loopback-only control API through an SSH local forward. Vendor CLIs and their credentials remain on the server and with the vendors. Claudexor can install a harness CLI on the host for you through a disclosed, exact-version flow — claudexor harness install, or Settings → Harnesses for a connected host: Claude, Codex, GitHub Copilot and OpenCode install one exact npm version that the host's runtime selects and shows before confirmation (a current runtime resolves Codex's npm latest once; the others use their release baseline), while the Cursor and Antigravity vendor scripts are downloaded in full and run in the visible terminal where you watch them; nothing
