Cache Warmer Extension for Magento 2

The Magento Full Page Cache Crawler / Warmer guarantees that your Full Page Cache solution remains continuously “warmed up,” enabling your store pages to be delivered at optimal speed. This extension is designed with efficient coding to minimize bandwidth, CPU usage, and crawling duration. Additionally, the Cache Warmer provides the option to exclude products that are unlikely to be viewed by your customers, such as hidden products and child products of configurable items.

    php bin/magento maintenance:enable
    php bin/magento setup:upgrade
    php bin/magento setup:di:compile

    php bin/magento maintenance:disable

Exclude URL Types - Select the types of URLs that should be excluded from the crawling process.

Custom URLs - Specify any additional URLs to be included in the crawling process.
