Overview

A look at altseat.com

Altseat is a menu bar application for macOS that manages multiple accounts across Claude Code, Codex CLI and Kimi Code. It displays each account's session and weekly usage limits in the menu bar and automatically starts commands on whichever account has remaining capacity. For Claude Code, when an account reaches 95% of its session or weekly limit, the agent writes a handoff message and the conversation continues seamlessly on the next available account in the same terminal. Each account maintains its own directory but shares settings and sessions through symlinks to each tool's default directory. The app supports up to 2 accounts free, and a lifetime license for one Mac unlocks up to 10 accounts per tool. It never handles passwords or tokens, works only between processes, and is signed and notarized by Apple.

FAQ

Will this get my account banned?
No. Altseat works only with accounts you added and are authorised to use. It never shares a login, never handles a token for anyone else, and never changes the login of a running process. Each account keeps its own limits. Separate accounts are set up using CLAUDE_CONFIG_DIR, CODEX_HOME, and KIMI_CODE_HOME, which are the vendors' own documented methods for running multiple accounts.
Can't two lines of shell do this?
Shell aliases can handle switching with CLAUDE_CONFIG_DIR, which Anthropic documents. Altseat adds menu bar usage visibility for every account, automatic launching that skips accounts at their limit, a Claude Code handoff that continues the conversation on the next account when near the limit, and shared settings and sessions across accounts. The free version supports 2 accounts so you can test it against aliases before paying.
Is it safe with my credentials?
Yes. Each tool signs in with its own login and Altseat never sees a password. By default it reads Claude usage from the status line Claude Code already outputs, not from the Keychain. Only if you enable the usage endpoint option does it read Claude's Keychain item to request detailed usage from Anthropic. Codex usage comes from Codex CLI's own local app-server. Altseat sends nothing elsewhere except the optional Anthropic request, license checks, and update checks.
What happens when an account reaches its limit?
In Claude Code, when the active account reaches 95% of its five-hour or weekly window and another account has room, the agent finishes its current step and writes a short handoff, the session ends, and Altseat starts claude on the next account with room in the same terminal, so the same conversation resumes. For Codex CLI and Kimi Code, the command starts on the next account with room at launch.
