A free, open source macOS app plus a Claude Code plugin. The plugin runs inside every Claude Code session and publishes its state; the app shows all your sessions in one window, notifies you when one needs you, embeds their terminals, and lets agents delegate work to each other, queue prompts and publish reports.

Does it replace Claude Code?

No. Your sessions are the real Claude Code, with every command, plugin, hook, skill and MCP server. OpenAdmiral plugs into Claude Code's own extension system and adds a desktop bridge on top.

Does my code or data leave my Mac?

No. Your code, prompts and sessions stay on your Mac: the app and your sessions talk through plain JSON files under ~/.claude/openadmiral, and there is no account. The app only sends one anonymous ping a day (a random install ID, the app version and your macOS version) so we can count installs, and you can turn it off. See openadmiral.com/privacy.

Do agents keep running when the app is closed?

Yes. Sessions run in the background with or without the app open, and scheduled prompts can wake a closed session up when they're due.

Do agents keep working with the lid closed?

Yes, with Underway on: the Mac stays awake while your agents have work, then sleeps as usual. It stops by itself below a battery floor (20% by default), if the Mac gets too hot, or after a time limit (8 h by default), and if OpenAdmiral quits, the Mac goes back to sleeping normally within 90 seconds. Keeping a Mac awake with the lid closed needs a small system helper: macOS asks you to allow it once, in System Settings → Login Items, and you can remove it from there.

Can I keep using my own terminal?

Yes. Keep working in your own terminal, or right inside OpenAdmiral. Both see the same sessions.

What do I need to run it?

A Mac with macOS 13 Ventura or later (Apple Silicon or Intel) and Claude Code. OpenAdmiral is free and MIT licensed.

Can I install it with Homebrew?

Yes: brew install --cask openadmiral/tap/openadmiral. It installs the same signed and notarized app as the download, and the app keeps updating itself.

How do I get help, or report a security issue?

Write to support@openadmiral.com, or open an issue on GitHub. Found a vulnerability? Please email security@openadmiral.com instead of opening a public issue (see openadmiral.com/.well-known/security.txt).

Is OpenAdmiral made by Anthropic?

No. OpenAdmiral is an independent open source project, not affiliated with or endorsed by Anthropic. Claude and Claude Code are trademarks of Anthropic.

It's an early alpha: expect rough edges and frequent updates, which the app installs itself. Builds are signed and notarized by Apple.

Privacy

Last updated: October 2026

OpenAdmiral is 100% local: your code, prompts, sessions and artifacts never leave your Mac, and there is no account. The app and your Claude Code sessions talk through plain JSON files under ~/.claude/openadmiral.

The one thing the app sends

To know how many people use OpenAdmiral, the app sends one anonymous ping when it starts and then once every 24 hours while it runs. It goes to openadmiral.com/api/ping and contains exactly:

id: a random identifier created on first launch and stored on your Mac. It is not derived from your hardware, your name or your account.
version: the OpenAdmiral version, for example 0.2.0.
os: always "macos".
osVersion: your macOS version, for example 26.0.
arch: your processor architecture: aarch64 (Apple Silicon) or x86_64 (Intel).

What it never sends

No code, file names, paths, prompts, conversations, project or agent names, costs, usernames or email addresses. The server does not store IP addresses and sets no cookies.

What we keep

One row per install identifier: when it was first and last seen, and the latest version, macOS version and architecture it reported. We use it only to count installs and active installs, and to see which versions are in use. It is never sold or shared.

Turn it off

In the app's menu bar, open Help and untick “Share Anonymous Usage Stats”.
Or set the environment variable OPENADMIRAL_TELEMETRY=0, or DO_NOT_TRACK=1.

With it off, the app sends nothing at all. Checking for updates downloads a small file (openadmiral.com/updates/latest.json) and sends no identifier.
