Blisk, is a Chromium-based browser that is built specially for web developers. It is designed specifically to allow developers to create and then test websites that look amazing and work seamlessly on all devices. The browser also comes with developer tools and some of its more interesting ones are the scroll sync, auto-refresh, and one-click screenshot features.
Last year, Mozilla released Firefox Developer Edition 38. Before then, it had no competitor until Blisk came into the scene.
If your OS is Linux or OSX, you’ll have to wait until June before a compatible version is released. For now, it’s only available for Windows.
