swapdex 0.1.7

Switch between multiple Claude Code and Codex login accounts, locally and safely.
Documentation

CI license local only

One command to flip your Claude Code or Codex CLI from your work account to your personal one, and back. No re-login, no browser, no copying tokens around. 100% local. Never touches the network.

Why

If you run Claude Code or Codex under more than one account -- a work seat and a personal subscription, a client's org and your own -- switching means logging out and back in every time. swapdex snapshots each logged-in account once, then swaps between them in place: the running CLI picks up the new account on your next message.

It is a switcher, not a rotator. It manages accounts you already own for distinct purposes. It has no feature for cycling accounts to get around a rate limit -- see What it will not do.

Safety is the design center: swapdex captures the live login before it swaps, so a switch can never lose or clobber an account, and it only ever hands the official CLI its own credentials -- no wrapper, no proxy, no client spoofing.

Concepts

  • Profile -- a named, point-in-time snapshot of a live login (the credential files, captured with add). It is a copy, not a live link.
  • Account -- the redacted identity a profile resolves to (email, tier, expiry). Shown by ls and status; never a token.
  • Switch -- use writes a profile's snapshot back into place atomically, backing up the current login first. One account is active per tool at a time.

Install

# crates.io (Rust)
cargo install swapdex

# Homebrew (macOS / Linux)
brew install youdie006/tap/swapdex

# npm (downloads the prebuilt binary)
npm install -g @youdie006/swapdex

# or the one-liner (prebuilt binary -> ~/.local/bin)
curl -fsSL https://raw.githubusercontent.com/youdie006/swapdex/main/install.sh | sh

Linux / WSL first (macOS Keychain support is planned). Requires the Claude Code and/or Codex CLI already installed and logged in. Full command, exit-code, and environment reference: docs/COMMANDS.md.

Use

# Save the account you're currently logged in as
swapdex add work            # snapshots Claude + Codex, whichever is logged in
swapdex add personal --tool claude

# See what you have and who's active
swapdex ls
swapdex status

# Switch (takes effect on your next message -- no restart)
swapdex use personal
swapdex use work --tool codex
swapdex use work --dry-run          # show what would change, write nothing

# Sessions grouped by the account active when they ran (needs sessionwiki)
swapdex sessions

# Recent local token usage per tool (5h/7d) -- tells you when to switch
swapdex usage

# Made a bad switch? Put back the login that was live before it
swapdex restore

status shows the live account per tool, matched back to a saved profile:

claude-code: you@work.com [max] (profile 'work')
codex: you@personal.com (profile 'personal')

The active account is always read from the live login, so if you /login directly in the CLI, swapdex reports the truth rather than a stale guess.

usage reads your local session logs (no network) to gauge how heavily you've been using each tool lately, so you know when to switch to a fresher account:

Local usage - this machine, approximate (not the billed quota):
  claude-code  5h:   8.2M tok / 12 sess    7d:   61.4M tok / 88 sess
  codex        5h:   1.1M tok / 3 sess     7d:   9.7M tok / 24 sess

It sums tokens from ~/.claude and ~/.codex transcripts, which are not tagged by account, so this is a machine-wide activity gauge rather than a per-account balance -- deliberately a hint, not a quota-dodging auto-rotator.

How it works

Each CLI keeps its login in a small on-disk file:

  • Claude Code: ~/.claude/.credentials.json plus the oauthAccount block inside ~/.claude.json
  • Codex: ~/.codex/auth.json

add copies the current login into a private store at ~/.local/share/swapdex. use writes a saved snapshot back into place atomically, backing up the current login first. For Claude, only the oauthAccount block of ~/.claude.json is swapped -- your projects, MCP servers, and settings in that file are never touched.

Safety

  • Every credential file swapdex writes is 0600; the store directory is 0700.
  • Writes are atomic (temp file created 0600, then renamed) so an interrupted switch can never leave a half-written credential that bricks the CLI.
  • Symlinked credential paths and running as root are refused.
  • use writes a backup of the current login (fsynced, or the switch aborts) before overwriting anything, and swapdex restore brings it back in one command if the switch was a mistake. The store keeps the last 2 backups per tool, and use warns when the outgoing login is not saved as a profile -- so save accounts you care about with add.
  • No token, refresh token, or home path is ever printed.

The store holds plaintext refresh tokens. Protect ~/.local/share/swapdex like ~/.ssh, and do not sync it across machines (it is single-machine, single-user by design).

What it will not do

These are structural properties, not promises -- the code is built so they cannot happen:

  • No network, ever. The switching binary has no HTTP client in its dependency graph (CI asserts this on every commit). swapdex cannot phone home or exfiltrate a token.
  • No auto-rotation. There is no --auto, --next, or --when-rate-limited flag. use only ever switches to a name you type.
  • No token export. There is no command that prints a saved credential.
  • No wrapper, no client spoofing. swapdex swaps the credential file that the official claude / codex binary already reads, then gets out of the way. It never sits between the CLI and the API, never proxies requests, and never presents itself as the official client. Your traffic is the real CLI's traffic.

Anthropic and OpenAI both permit multiple accounts for genuinely different purposes but forbid using multiple accounts to get around a single workload's rate limit, and forbid routing subscription OAuth tokens through third-party tools or spoofing the official client. swapdex is built for the former and structurally cannot do the latter -- it only ever hands the real CLI its own credentials. See Anthropic Usage Policy and OpenAI Usage Policies.

MCP (read-only)

swapdex mcp runs a read-only MCP server exposing whoami and list_accounts so an agent can see which account is active. There is deliberately no switch tool -- an agent can never change your account.

claude mcp add swapdex -s user -- swapdex mcp

Works with

swapdex is the accounts layer of a small local AI-CLI stack:

  • sessionwiki -- index, search, and resume your AI coding sessions. swapdex sessions groups them by account.
  • prodex -- share one logged-in ChatGPT Pro session across agents. swapdex coexists with it without touching its auth.

Roadmap

Being considered, explicitly opt-in and advisory-only:

  • Per-directory hints (cross-tool). Bind a directory to a profile and have swapdex resolve <dir> suggest the right account ("this directory is bound to work -- run swapdex use work"). It would cover both Claude (CLAUDE_CONFIG_DIR) and Codex (CODEX_HOME) in one binding. It will never be a shell wrapper, never auto-switch, and never let anything but an explicit swapdex use change the active account -- that bright line is what keeps swapdex a switcher, not a rotator.
