Is Muse Code down? User reports show no current problems with Muse Code
Muse Code is Meta's coding agent that runs in your terminal and edits real project files. When Muse Code down reports appear, this page tracks the live Muse Code status for you. It separates a service fault from an install, key, or sandbox problem on your machine.

Is Muse Code down right now?
When Muse Code is down, new sessions fail to start and running agents stop answering. Prompts return service errors instead of code changes. Fresh Muse Code down reports from many developers at once mark a platform fault.
A broken local setup fails in quieter ways. One machine refuses while a teammate’s session runs fine on the same network. Bad keys, stale installs, and sandbox faults stop the agent before the service gets a say.
Is Muse Code down for me or everyone?
Check the Muse Code status at the top of this page before you touch your setup. Green means Meta servers answer as normal, so the fault sits in your install, key, or shell. Red points to a Muse Code outage hitting many users at once. Then settle it directly: is Muse Code down for me alone, or do fresh reports match your exact error? Plenty of readers bookmark Mux outage for the same reason they bookmark this page.
What does Muse Code need before the first run?
The tool installs with one command, then asks you to sign in or paste a Meta API key. It also needs basic shell tools on the machine, such as curl and a temp folder it can write to. A missing tool stops the installer with a plain message naming it.
On Linux, shell commands run inside a bundled sandbox helper. If that helper fails on your host, every command errors out even though the agent itself loads.
How does Muse Code sign you in?
On a desktop, the agent opens your browser to approve the session. On a server with no browser, an API key in the environment does the job instead. A key set in the shell wins over any stored browser session. That order explains many wrong account surprises, where the tool runs as another user than the one you approved.
Can Muse Code run across several sessions at once?
Yes. Each terminal window holds its own session with its own task. Sessions work in parallel, so one long refactor does not block a quick fix elsewhere.
When does Muse Code stop in the middle of a task?
A session stalls when its link to the service breaks or the thread state goes bad. Long idle gaps, a VPN switch, or a model change mid thread can poison the next turn. Starting a fresh session clears that class of fault at once.
Common Muse Code Problems and Fixes
Run these checks when Muse Code will not start, sign in, or finish a task.
Open a fresh terminal
The install updates your shell path, and old windows never see it. A new terminal finds the muse command at once. If the command still fails, run the source line the installer printed at the end.
Quote your API key
Meta keys contain pipe characters that shells read as command separators. An unquoted export leaves the key empty and every call fails on auth.
Check which sign-in wins
An exported key overrides the browser session on every run. Print your environment to see whether a key variable is set. Remove it if you want the browser account, or keep it and drop the browser login.
Fix the sandbox helper
If every shell command fails as an environment error, the bundled sandbox helper is not running on your host. Install the missing system tools the error names, then restart the agent.
Start a clean session
A thread that fails on every retry with the same state error is poisoned. Close it and open a fresh session in the same folder. Your files stay as they are.

Frequently Asked Questions
Why does my terminal say muse command not found?
The shell path update only lands in new terminal windows. Open a fresh window and try again. If the error stays, rerun the installer and watch for a missing tool message near the end.
How do I fix an authentication error at startup?
Check the key first. An unquoted key with pipe characters exports as an empty value, so the service rejects every call. Set it inside double quotes, open a new session, and try again.
What does a model not found error mean?
The session asked for a model name the service does not host. Pick a model from the list the tool itself offers.
Is Muse Code down when my session freezes?
Not always. A frozen session with a green status above points at your thread or connection. Start a fresh session and repeat the last prompt. A red status means the service side is at fault.
Can Muse Code write anywhere on my machine?
Writes stay inside your workspace and a temp folder. System folders stay read only, and git data stays protected. A write error outside the workspace is the sandbox doing its job.
Does Muse Code work over SSH?
Yes, with an API key, since no browser can open on a plain server session. Export the key in the shell before you start.
