Simulator Panel

Responsive design breaks in unexpected places — a layout that looks perfect at 1440px can collapse completely at 375px, and testing each breakpoint manually in a single browser window is slow and error-prone. Lodos Simulator Panel shows your website or web app simultaneously across multiple device sizes: phones, tablets, and desktops rendered side by side in a single view. Spot layout issues, font scaling problems, and touch-target violations at a glance before they reach production.

Each simulated device comes with a full built-in DevTools suite: browser console for JavaScript errors, network panel for request inspection, and storage inspector for cookies and localStorage. Performance profiling identifies slow render paths and resource bottlenecks per device. The accessibility panel flags contrast failures and touch targets that are too small for reliable interaction on mobile — catching the issues that automated CI checks often miss.

For development teams and agencies reviewing client builds, Simulator Panel eliminates the need for physical device labs or external browser testing services. Capture screenshots across all configured devices simultaneously for client approval or QA documentation. Custom device configurations let you add specific resolution profiles for non-standard hardware your users actually run. Because Simulator Panel integrates with the rest of Lodos, a bug spotted during testing becomes a task card in Task Management with one click.
