Browser Cookie Jar Test Center 🍪

Test 1: Find Per-Domain Cookie Count Limit

This test iteratively sets cookies one-by-one and verifies the entire set after each addition. This precisely identifies the maximum number of cookies allowed for this domain.

Test 2: Find Individual Cookie Size Limit

This test finds the maximum size of a single cookie (name + value) by creating a cookie, checking if it was set, and incrementally increasing its size until it fails.

Test 3: Find Total Cookie Jar Size Limit

This test finds the total storage limit by running multiple tests with different cookie sizes (from 4KB down to 1KB) and reporting the maximum size found. This provides a more accurate result than a single test.

Test 4: Find Max Cookie Number for a Given Size

This test determines how many cookies of a specific size your browser can store. It correctly calculates the cookie's total size (name + value) to fill the jar.

Cookie Attribute Setter

Create a custom cookie to observe how different attributes work. The table below will update in real-time.

Note: `SameSite=None` and `Partitioned` both require the `Secure` attribute. `HttpOnly` cannot be set via JavaScript.

This table shows all non-HttpOnly cookies currently stored for this domain.
