Finally I don't have to go to other sites to check web pages responsiveness. Thank you so much developer.
good
useless tool
Not working in local host
waste of time
Useless not working on localhost
Srs, achei legal, porém faltou duas opções fundamental para nós desenvolvedor! 1. A informação da resolução de cada dispositivo ao lado no nome dele ou se passar o mouse em cima deveria aparecer. 2. Campo de adicionar a resolução manual caso não tenha disponível. Por isso não irei usa lo, pq não vai me servir de confirmação com os testes com o inspecionar do navegador.
