When interface changes need review, visual regression testing tools help teams compare captures and assess visual differences. Compare visual diff modes and cross-browser capture, then check browser count against the coverage your testing setup requires. CI/CD integrations and approval workflow show how each option fits into building and review processes; project limits, free plan availability, and paid-from pricing add practical constraints. Happo, Screenster, and SmartUI are among the tools included, alongside Argos. Consider how the listed capture, comparison, and review features fit your team's workflow.
