Your Claude accounts,
on an infinite loop.

Hit a usage limit? Mobius switches to your next account. When the limit resets, it switches you back. You just keep working.

macOS 14+ · free & open source · Claude Code CLI + Claude Desktop

Mobius popover with account cards and usage gauges

The loop

Exhaust. Fall back. Recover. Repeat.

The menu bar icon tells the whole story — blue when your primary is working, amber while a fallback covers for it, back to blue when the loop closes.

T+0s

Primary is working

You work on your main account while Mobius quietly reads your local session logs. Limit detection never touches the network.

T+5s

Limit hit → fallback

The moment your account hits its limit, Mobius switches you to the next one. No logout, no re-login, nothing to click.

on reset

Reset → back to primary

Mobius remembers the reset time. Once it passes, you're back on primary automatically — a 120-second cooldown keeps it from ping-ponging between accounts.

Server-side throttles ("not your usage limit") are filtered out — Mobius only switches when it's really your account's limit.

Built for daily driving

Small app. Strong opinions.

One-click switching

Click a card and you're on that account. If a switch fails, everything rolls back — there's no half-switched state.

Usage gauges

5-hour and weekly meters per account, with time-to-reset. Fetched only when you open the popover, cached 4 minutes.

No background polling

Limits are detected from local logs — zero network. The only server calls are the usage gauge (when you open the popover) and a once-a-day update check. Both can be switched off.

Claude Desktop tooEXP

Connect an account once, and Desktop follows every switch with a 2–5 second restart.

Spots dead logins

If an account's login expires, its card shows a "Sign in again" button — and auto-switch skips it until you do.

Speaks your language

English, 한국어, 日本語 — follows your system language, or pin one in Settings.

For terminal people

The app is optional. The loop isn't.

Everything works from the menu bar — but if you live in a terminal, the mobius CLI drives the same engine.

$ mobius list

Install

Ninety seconds to your first switch.

1

Download & drag

Download the DMG from Releases, open it, and drag Mobius into Applications.

2

Open it (once, the long way)

Mobius isn't notarized by Apple, so the first launch is blocked. Go to System Settings → Privacy & Security and click "Open Anyway". Only needed once.

3

Add your accounts

Click the ∞ icon in the menu bar → Add Account. Sign in to each Claude account once — Mobius handles everything after that.

Why the warning? Mobius is open source and self-signed rather than paying for Apple notarization. You can read every line it runs — or build it yourself with Scripts/make-app.sh.

Stop babysitting your limits.

Put your accounts on the loop and forget they're separate.
