What is cookietuner?

A command-line tool that reads cookies straight from your local macOS browser stores. It decrypts Chrome's encrypted cookie database via the macOS Keychain (Chrome 130+ format) and parses Safari's binary Cookies.binarycookies file directly, with no extensions involved.

When a store can't give you what you need, cookietuner capture opens a clean Chrome window instead, waits while you sign in yourself, and keeps the cookies that session set.

Features

• Chrome support — decrypts cookies using macOS Keychain, Chrome 130+ format.
• Safari support — parses the binary cookies format with SameSite detection.
• Throwaway sign-in capture — a fresh Chrome profile, deleted afterwards, for session and HttpOnly cookies that never reach disk.
• Sign in from the Passwords app — optionally loads Apple's iCloud Passwords extension, so nothing is typed.
• Multiple output formats — table, short, line, and JSON.
• Domain filtering — filter by exact domain (x.com matches .x.com, not api.x.com or dropbox.com).
• Profile selection — choose which browser profile to read from.
• Cookie metadata — expiration, Secure, HttpOnly, and SameSite flags.

Usage

List cookies

# Chrome cookies (browser flag is required)
cookietuner cookies -b chrome

# Safari cookies
cookietuner cookies -b safari

# Filter by domain
cookietuner cookies -b chrome -d google.com

# Pick a Chrome profile
cookietuner cookies -b chrome -p "Profile 1"

Output formats

Capture a fresh session

Opens Chrome on a temporary profile with none of your history or logins. You sign in by hand; cookietuner never types, fills or sees your credentials. The profile is deleted when the capture ends, including on timeout, Ctrl-C or error.

# Wait for specific cookies, then print them and close the browser
cookietuner capture --url https://example.com/login \
  -d example.com --until session_id --until csrf_token -o json

# Without --until, the capture ends when you close the window
cookietuner capture --url https://example.com/login -d example.com

# Sign in from the Passwords app instead of typing
cookietuner capture --url https://example.com/login \
  -d example.com --until session_id --passwords

# Route the session through a proxy
cookietuner capture --url https://example.com/login \
  -d example.com --proxy socks5://127.0.0.1:1080

Cookie values go to stdout on their own and progress goes to stderr, so the output pipes straight into a secret store:

cookietuner capture --url https://example.com/login \
  -d example.com --until session_id -o json | my-secret-store put example-session

This reaches cookies a store reader can't: session cookies, cookies kept only in memory, and HttpOnly cookies on a macOS version that denies access to Chrome's own store.

List browser profiles

# All profiles
cookietuner profiles

# Filter by browser
cookietuner profiles -b chrome

Requirements

• macOS (the tool reads macOS-specific cookie stores).
• Python 3.14+.
• Chrome and/or Safari.
