Shopify checkout modes are used in order to help increase success on specific site. PrismAIO currently supports 3 checkout modes:
Fast mode is best utilized on sites that drop products without bot protection or for restocks. In order to get the most out of fast mode, it is best to run with variants for the product or with a direct link. Fast mode is the fastest mode for shopify.
Safe mode is best utilized on sites that drop products with bot protection. Safe mode is designed to pass Shopify bot protection while acting like a "human". Often, safe mode is recommended for sites that drop a password page prior to the drop i.e. DSMNY, DSML, etc. Safe mode does not preload an existing checkout.
Safe Preload mode is best utilized on sites that drop products with bot protection. Safe Preload is designed to preload an existing checkout in order to try and pass queue at drop time. This is the best option to run on sites like Kith and Undefeated.
