About the MetaSizer
MetaSizer scans all metafield sizes across your Shopify store to help you spot oversized fields before writes fail. With Shopify's API 2026-04 limiting JSON metafield writes to 128 KB, this free read-only app gives you complete visibility into your metafield data.
Scan products, variants, collections, and shop metafields in one click. See exact byte size, percentage of the limit, and risk status for every entry. Schedule daily or weekly scans with email alerts when changes are detected. Export results as CSV or JSON to share with your team or agency.
The app is 100% read-only and requires just one permission—it never modifies your store data. Stay ahead of the 128 KB cap and avoid failed writes while monitoring metafield performance impact on your storefront.
