Team-based review history versus usage-based screenshot billing
Vizzly is the better fit when you want visual regression testing for agents and teams: approved baselines, comments, review decisions, local checks, and predictable team pricing.
Not with Vizzly. Unlike DOM-based tools (Percy, Chromatic), Vizzly accepts screenshots from any source: web, native mobile, React Native, design tools.
Vizzly's local loop shows visual changes against approved baselines as you code. Other tools usually wait until CI before review history exists.
