Powered by LG’s proprietary Linux-based OS, webOS (version 6.0+) delivers a minimalist, user-centric interface optimized for speed and simplicity. Its lightweight architecture minimizes RAM/CPU usage, enabling smooth multitasking on mid-to-high-end hardware. The card-style UI organizes apps (Netflix, Disney+, Apple TV+) and live TV inputs into a horizontal ribbon, navigable via the Magic Remote’s point-and-click or voice commands. Built-in AI (ThinQ AI) analyzes viewing habits to prioritize content recommendations and sync with smart home devices (lights, thermostats). Developers leverage webOS Open Source Edition to create apps using JavaScript/HTML5 frameworks, ensuring compatibility across LG’s ecosystem. The platform supports 4K/HDR streaming, Apple AirPlay 2, and HDMI 2.1 gaming features (ALLM, VRR), while the webOS Store offers curated apps like Spotify, YouTube, and Plex. Unique features include Multi-View for split-screen streaming and NFC-based Magic Tap for instant mobile-to-TV pairing. Hospitality-focused modes enable hotel-style content management. Regular firmware updates (5+ years support) enhance security and add functionalities like cloud gaming (Stadia, GeForce NOW).
