FAQ

Can I use my existing BrowserStack/Sauce Labs setup?

Yes. Vizzly accepts screenshots from any source. Keep your current infrastructure.

How does local TDD compare to Percy?

Percy always goes to cloud and costs per screenshot, even locally. Vizzly's vizzly tdd runs entirely local and free.

Can I test mobile apps?

Yes. Vizzly accepts any screenshot with unified diffing. Percy's native SDK bypasses their browser rendering and uses basic ImageMagick diffing.
