Verified install command

Meta currently publishes the same command on its Muse Code product page and Aug 5 research announcement:

macOS or LinuxOfficial command
curl -fsSL https://dev.meta.ai/install.sh | bash

Before running a piped installer

A curl-to-shell command downloads a script and immediately passes it to your shell. That is convenient, but the source still deserves inspection—especially on a development machine with repository credentials.

  1. Open the current Meta Muse Code page through the source link at the end of this guide.
  2. Confirm the command still matches the one shown above.
  3. Confirm you are on macOS or Linux; those are the platforms named by Meta’s current installer wording.
  4. Use a shell and account context you understand. Do not elevate privileges unless the official flow explicitly explains why.
  5. Read the terminal output and authentication prompts before approving access.

Meta’s public overview routes users into its current developer access surface. The exact account prompts can evolve during beta, so this guide does not freeze a screenshot of an authentication flow that may change. Follow the current Meta prompts, check the selected pricing tier, and start in a repository where you can inspect every change.

What this guide does not publish

There is no Windows command here because a current Muse Code Windows command was not present on the official pages checked for this build. There are also no invented package-manager aliases, uninstall commands, credential-reset steps, or configuration paths.

That omission is deliberate. Search results for “Muse Code install” contain unrelated software with similar names. A plausible-looking command is not evidence that it installs Meta Muse Code.

If setup does not complete

  • Confirm the current beta access status before changing local configuration.
  • Re-copy the command from Meta rather than from a search snippet.
  • Confirm your network can reach dev.meta.ai.
  • Record the exact terminal error and move to the safe troubleshooting guide.
  • For an interrupted agent task after successful setup, read how the documented event log and resume model differs from installation recovery.
