title: Platform support
description: What OpenCodex can do on macOS, Windows and Linux, and why a few capabilities stay platform-specific.
---

OpenCodex runs on macOS, Windows and Linux. Most of it behaves identically on all
three; a few capabilities depend on something the operating system provides, and
this page says which, and why.

## Everywhere

| Capability | Notes |
| --- | --- |
| Proxy, routing, provider adapters | The core runtime is platform-neutral. |
| Background service | Three native backends: launchd on macOS, Task Scheduler **or** WinSW on Windows, a systemd user unit on Linux. |

P2 Badge Qualify Linux background-service support

On Linux without a systemd user instance, and in every Docker environment, diagnoseService() explicitly reports the background service as unsupported (src/service.ts:4185-4187), but this row lists it under “Everywhere” without that prerequisite. Add the systemd/non-Docker qualification and the supported process-supervisor alternative; otherwise users on Alpine, non-systemd distributions, or containers are told a capability exists that ocx service refuses.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the backend count.

The row names four concrete implementations: launchd, Task Scheduler, WinSW, and systemd. “Three native backends” understates the Windows choices. Distinguish three platforms from four backend implementations.

Proposed wording 
-| Background service | Three native backends: launchd on macOS, Task Scheduler **or** WinSW on Windows, a systemd user unit on Linux. |
+| Background service | Four native backends across three platforms: launchd on macOS, Task Scheduler **or** WinSW on Windows, and a systemd user unit on Linux. |

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
| Background service | Three native backends: launchd on macOS, Task Scheduler **or** WinSW on Windows, a systemd user unit on Linux. |
| Background service | Four native backends across three platforms: launchd on macOS, Task Scheduler **or** WinSW on Windows, and a systemd user unit on Linux. |

In `@docs-site/src/content/docs/reference/platform-support.md` at line 15, Update
the “Background service” support-table entry to distinguish three supported
platforms from four backend implementations, accurately counting launchd, Task
Scheduler, WinSW, and systemd.

### Provider keys in the OS credential store

Supported on all three platforms, **when an unlocked OS credential service is
available**: Keychain on macOS, Credential Manager on Windows, libsecret on
Linux. A locked keyring or a headless session has no unlocked service, so the
store is unavailable and OpenCodex says so rather than silently falling back.
See [Providers](/reference/configuration/providers/) for the storage rules.

## macOS only

### Claude Code auto-connect

Injecting `ANTHROPIC_BASE_URL` and the Claude Code levers into your session
happens through the launchd user domain, which has no single equivalent
elsewhere.

On Linux the three plausible mechanisms each reach a different set of processes:
`systemctl --user set-environment` reaches only systemd-spawned units,
`~/.profile` only login shells, and `~/.bashrc` only interactive non-login
shells. There is no one place that covers a user's whole session.

On Windows the equivalent is `HKCU\Environment`, which is genuinely persistent
rather than per-boot. That is the problem: it would move a bearer token from a
domain that empties at reboot into a registry hive that does not, which is a
change in how long the credential sits on disk and who can read it. That
decision needs a security review rather than a port.

Everything else Claude Code needs works on all platforms. You can set the same
variables yourself, or run `ocx claude`, which passes them to the child process
directly.

## Import versus paste

### Meta Muse Code

On macOS, OpenCodex imports the API key the Muse Code CLI already stored after
`muse login`, so you are not asked to provision a second one.

P1 Badge Include the Meta Muse unsupported-use warning

When a user discovers meta-muse through this new page, these lines present reuse of the Muse CLI credential as a normal import, while the canonical provider documentation at docs-site/src/content/docs/guides/providers.md:472-478 says Meta scopes it to its own CLI, OpenCodex use is unsupported, subscription coverage is not authorized, and calls should be treated as billable. Link to that canonical section and surface the warning here so readers do not enable the provider expecting their Muse subscription to cover it.

Elsewhere it asks you to paste the key instead. Meta ships no native Windows
CLI, and on Linux the CLI exists but where it keeps its credential has not been
verified, so OpenCodex declines to guess at a credential store. The same key is
visible in [Meta's developer console](https://dev.meta.ai), and a pasted key
faces the same format check and the same live validation against the Model API
as an imported one.

## Windows notes

The Windows service can run under Task Scheduler or as a native WinSW service,
and those are mutually exclusive. `ocx service repair` refuses to proceed when
it finds state for both, because guessing which one you meant is how a machine
ends up with two proxies fighting over a port.

Console output on a non-English Windows install arrives in the system code page
rather than UTF-8. OpenCodex decodes it accordingly, so an account name with
non-ASCII characters resolves correctly.

P2 Badge Limit the Windows decoding promise to supported code pages

For non-English Windows locales outside the implemented Korean, Japanese, Chinese, and Windows-1252 groups, this guarantee is false: decodeWindowsTextBytes() falls back to lossy UTF-8 for unsupported code pages (src/lib/windows-text.ts:122-131), and tests/windows-text-decoding.test.ts:28-33 explicitly verifies that a Russian CP1251 name remains corrupted. Qualify the statement to the supported locale families instead of promising that every non-ASCII account name resolves correctly.

## When something is unavailable

OpenCodex states the actual reason rather than disabling a control silently. If
a capability is unavailable on your platform, the error or the dashboard says
which mechanism is missing and what the supported alternative is. If you hit one
that does not, that is a bug worth reporting.
