clauth 0.1.0

A simple Claude Code account switcher. Select a profile, hit enter, done. Supports OAuth Claude Pro/Max accounts and API endpoint profiles.

? clauth
  ● work        Claude Pro / OAuth
    personal    Claude Pro / OAuth
    api-dev     https://api.notanthropic.com · API key set
  + New profile
  + New from current profile
    Quit

Claude Code stores session in two places: ~/.claude/.credentials.json and the env block inside ~/.claude/settings.json (base URL and API key). Switching accounts means editing both by hand, every time.

clauth keeps snapshots of both files for each profile; on change it swaps the .credentials.json and changes only the API variables in the env block of .settings.json - everything else stays intact.

Install

Supported platforms:

• Linux
• macOS
• Windows (Git Bash / MSYS2)

Via cargo (recommended):

cargo install clauth

Via install script (no Rust toolchain required):

curl -fsSL https://raw.githubusercontent.com/uwuclxdy/clauth/mommy/install.sh | bash

The script detects cargo and uses it when available. Pass --nocargo to force a binary download instead:

curl -fsSL https://raw.githubusercontent.com/uwuclxdy/clauth/mommy/install.sh | bash -s -- --nocargo

Build from source:

git clone https://github.com/uwuclxdy/clauth
cd clauth
cargo build --release
# binary at ./target/release/clauth

Updates

Binary installs (non-cargo) check for updates silently in the background each time clauth starts. The updated binary takes effect on the next run. No action needed.

Cargo updates clauth via cargo update.

Quickstart

Capture your current Claude Code session:

clauth
# Select "+ New from current profile"
# Enter a name, e.g. "work"

Create a second profile while logged in to a different account, then switch between them with:

clauth
# Select the profile → "Switch to this profile"

The active profile is marked with ● in the list.

Profile types

Claude Pro (OAuth) -- leave base URL blank. clauth captures the OAuth token from your running session and restores it on switch.

API endpoint -- set a base URL and (optionally) an API key. Works with the official Anthropic API or any compatible proxy.

You can edit a profile's URL and key at any time without losing its stored credentials. The "Edit" action in the submenu updates config.toml only.

Storage layout

~/.clauth/
  profiles.toml          # profile order + active marker
  profiles/
    work/
      config.toml        # base_url, api_key
      credentials.json   # OAuth token snapshot
    personal/
      ...
