LT Browser enables testing website responsiveness across multiple device viewports. It supports simultaneous interaction with up to six devices, dedicated DevTools for each viewport, and network throttling to simulate conditions like 3G, 4G, or offline. Users generate performance reports, capture full-page screenshots, record videos, and log bugs with one click. Built on the latest Chromium, it offers hot reload, JavaScript error reports, and unlimited custom viewports. Integration with project management tools shares bugs directly.
