CartLeap: Cart Handoff

CartLeap carries cart contents when shoppers move from links inside Instagram, Facebook, Messenger, TikTok, and similar apps to their main browser. It detects the handoff, restores the carried cart, asks before replacing a different cart already on the device, and welcomes shoppers back so they can continue toward checkout. Guest shoppers do not need an account. CartLeap does not maintain a separate server-side record for each cart.
