Browser Cookie Viewer: See, Search, and Understand Your Cookies
View all cookies stored in your browser with details like domain, expiration, SameSite policy, and secure flags. A lighter alternative to digging through DevTools.
Introduction
Cookies power most of the web: session logins, shopping carts, analytics tracking, consent preferences. But unless you regularly open Chrome DevTools and navigate to the Application tab, you probably have no idea what cookies are sitting in your browser right now. Our Cookie Viewer shows you every cookie in a clean, searchable table with columns for name, value, domain, path, expiration, and security flags. It is especially handy for developers debugging authentication flows or testing GDPR consent banners.
Step-by-Step Guide
Open the tool
Navigate to the Cookie Viewer page. It immediately reads the cookies accessible to the current site and displays them in a sortable table. No extra permissions needed.
Browse and search
Scroll through the table to see all cookies, or use the search bar to filter by name, domain, or value. This is much faster than scrolling through the raw list in DevTools.
Inspect individual cookies
Click any row to see the full cookie details: the raw value (useful for decoding session tokens), the exact expiration timestamp, and the security attributes like HttpOnly, Secure, and SameSite policy.
Pro Tips & Best Practices
When debugging login issues, check if the session cookie has the "Secure" flag set. If it does, the cookie will not be sent over HTTP connections, only HTTPS.
Look at the "SameSite" attribute on your authentication cookies. If it is set to "Strict," your login will break when users arrive from external links. "Lax" is usually the better option.
Sort by expiration date to find cookies that are set to expire far in the future. These are often tracking cookies that persist across sessions.
Common Mistakes to Avoid
Frequently Asked Questions
Why are some cookies not showing up?
Cookies marked as HttpOnly cannot be accessed by JavaScript, so browser-based tools cannot see them. These are typically session cookies set by the server for security purposes.
Can I delete cookies through this tool?
The viewer is read-only by design. To delete cookies, use your browser settings or DevTools. This prevents accidental deletion of important session data.
What is the SameSite attribute?
SameSite controls whether a cookie is sent with cross-site requests. "Strict" means the cookie is only sent on same-site requests. "Lax" allows it on top-level navigations. "None" sends it everywhere but requires the Secure flag.
