Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureA successful shop needs great products, rich functionality, and eye-catching design — a storefront powered by data. Metafields are a tool for storing custom data: specifications, downloadable files, related products, variant descriptions, Google/Facebook data, banners, etc. Our app is a tool for managing and displaying metafields on the storefront, migrating data between stores, creating backups, and more.
Shopify API 2026-04 caps JSON metafield writes at 128 KB (down from 2 MB). Apps using JSON before April 1 are grandfathered at 2 MB, but new integrations and manual writes are subject to the cap. Large metafields also impact storefront performance. MetaSizer scans products, variants, collections, and shop metafields in one click. You get exact byte size, percentage of the limit, and risk status for every entry.
