WordPress migration plugin that treats serialized PHP and JSON as typed data structures during search-replace, with a diff preview showing exactly what will change before committing
WordPress has millions of sites and every agency runs migrations constantly, yet every existing tool has this same silent data corruption bug
Built for WordPress developers migrating JSON-heavy sites.
Every other migration tool operates on raw strings and silently corrupts JSON or serialized objects; type-aware diffing makes corruption visible and preventable before it happens

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
WordPress developers migrating JSON-heavy sites. No search-volume data provided, but the pain signal (corrupted JSON after migration) suggests active friction among a subset of WP users handling structured data.
Competition & the opening
Six named competitors dominate: WP-CLI, Interconnect/it Search Replace DB, WP Migrate DB Pro, All-in-One WP Migration, Migrate Guru, and Duplicator Pro. The gap is specific: existing tools convert empty JSON objects {} into arrays [], corrupting schema-dependent data—none explicitly advertise JSON-aware search/replace logic.
What's hard to build
Requires deep PHP serialization parsing and JSON schema understanding to detect and preserve object/array type distinctions during find/replace. Integration with WordPress core migration hooks and testing across plugin ecosystems adds significant infra burden.
Why now
WordPress migrations remain manual and error-prone; JSON data corruption in serialized PHP is a real edge case that general search-replace tools miss.
