One operator. No agency in the loop.

Solvir is run by Chen Xuanzhao, a sole proprietor in Shenzhen. The tools come from hundreds of conversations with Shopify, Shoplazza and WordPress merchants who kept hitting the same problems.

Self-serve: Submit a URL or drop a file. No sales call, no onboarding.
No access to your ad accounts: Diagnostics run against your public storefront. We never ask for Meta or Google logins.
Files stay on your device: Performer Tag processes images in your browser. Nothing is uploaded or retained.
