Shopify shipping migration auditor

Will your Shopify app survive market-driven shipping?

Merchant-owned shipping is moving from DeliveryProfile to Markets. Legacy reads can become stale and writes can succeed without changing live settings. Find those paths before rollout.

What the scanner checks

A migration report developers can act on.

MarketReady uses transparent, versioned rules sourced from Shopify’s upgrade guide. It does not send code to an LLM or claim certainty where static analysis cannot know profile ownership.

01

Legacy API inventory

Find all eight affected DeliveryProfile fields and mutations with file names, line numbers, and matching code.

02

Silent failure patterns

Flag write paths that can report success while leaving a migrated merchant’s live configuration unchanged.

03

Scopes and branching

Check for read_markets, write_markets, read_product_listings, and ShopFeatures.marketDrivenShipping.

04

Upgrade path

Choose among app-owned profiles, Contextual Product Feeds, Markets reads, and Markets writes.

Privacy architecture

Your source code stays on your machine.

The ZIP is decompressed in browser memory. Only short matching lines are placed in a report stored in localStorage. There is no upload endpoint, repository token, database, or analytics payload containing source.
