Provide a managed compatibility-testing service for extension releases using a maintained matrix of Chrome, Brave, Edge, Vivaldi, high-traffic websites, and common conflicting extension categories. Each test cycle delivers reproducible defect reports, performance comparisons, screenshots or recordings, and a compatibility certificate for releases that pass. Begin with manual testing on standardized browser profiles, then productize repeatable test scenarios and environment provisioning as demand becomes clear.

Extensions increasingly run across several Chromium-based browsers while browser and website updates can silently change their behavior. Recent signals span many unrelated extensions and repeatedly identify cross-browser failures, site-specific breakage, update regressions, and extension conflicts.
