EPHEMERAL SHADOW TESTING

Safe Updates Sandbox

Updates tested on a copy first.

Never let updates run raw in production. Autvy clones your site to a shadow sandbox, verifies layout and checkout, and only then cutovers.

Incident Spectrum

What this engine neutralizes

Major WooCommerce or WordPress core database schema migrations
Plugin updates that introduce CSS layout breakage on mobile viewports
Third-party payment gateway updates that break JavaScript checkout button handlers
Unvetted automated host auto-updates pushing untested plugin releases

Under The Hood

Hard-linked Copy-on-Write (CoW) shadow directory provisioned locally on host.

03

SANDBOX UPDATE

04

VERIFY VISUALS
