Features

• Any source, one UI. Sign in with Xtream Codes credentials, paste an M3U / M3U8 URL or a direct stream link, or load a playlist file from your device. The app detects the mode automatically.
• Live TV with category filtering, channel search, channel-number entry, a virtualised list, and inline EPG (now / next / today).
• Catch-up TV and replay. Replay programmes from your provider's archive and pause or rewind behind live, with a full-programme seekbar.
• Custom playlists built in a full in-app editor: pull channels from any playlist, reorder and group them, rename, renumber, find and replace, check links, and export as .m3u.
• Add a stream from any website. Paste a page URL and the app sniffs the network for playable HLS / DASH streams, with quality labels and multi-select.
• Movies (VOD) and Series library with poster grids, detail dialogs, and season / episode navigation.
• Full schedule grid on the EPG page, with timezone-aware "all times local" rendering, custom EPG sources, and channel mapping.
• A player for everything. Three embedded engines (ArtPlayer, Video.js, Shaka) cover HLS, MPEG-TS, MPEG-DASH with ClearKey, and HEVC (with one-click install of the Windows HEVC extension). Picture-in-picture included.
• Embedded subtitles from MP4 files everywhere and MKV files on desktop, plus audio track switching and automatic audio repair: AC-3 / E-AC-3 / MP2 / DTS transcoded on the fly through a bundled FFmpeg (Windows / Linux).
• External players. Hand any stream to MPV or VLC on desktop (with window reuse), or to any installed video app on Android.
• Multiple playlists, switchable from the sidebar without re-entering credentials, each with its own favorites, watchlist, progress, and health panel.
• TV-first navigation. Spatial focus (D-pad / arrow keys) is wired across the whole app via spatial-navigation-polyfill. Hit targets, focus rings, and reflow tested for 10-foot UI, plus a TV safe-area setting for overscan.
• 16 languages including RTL (Arabic, Urdu), translated before first paint so there's no flash of English.
• Light and dark themes with seven accent colors, both first-class. Honours prefers-color-scheme, prefers-reduced-motion, and prefers-contrast.
• Adjustable font scale (Default / Medium / Large / X-Large) plus a responsive root size that scales the whole UI on 4K and 8K displays.
• Self-updating desktop builds (Windows NSIS and Linux AppImage) via the Tauri updater, signed with minisign and served from GitHub Releases, with stable and beta channels and a "What's new" dialog after each update.
• Backup and restore. Export playlists, preferences, and settings as one file and import them on another device.
• Offline-friendly persistence. Credentials and preferences live in the OS app-data dir on Tauri builds, with a localStorage / cookie fallback on the web build.
• No tracking, no ads, no telemetry. The app collects nothing about you or your viewing habits.

via winget

The Microsoft Store listing is federated through winget, so you can install without opening the Store:

winget install --id 9NN162Z0WXSR --source msstore

macOS: "Extreme InfiniTV.app" cannot be opened

The macOS build is not yet notarized by Apple, so Gatekeeper blocks it on first launch with a message like "Apple could not verify Extreme InfiniTV.app is free of malware". After dragging the app from the .dmg into /Applications, remove the quarantine flag from a Terminal:

xattr -dr com.apple.quarantine "/Applications/Extreme InfiniTV.app"

Then open the app normally. You only need to do this once per install.

Develop

Requirements: pnpm (the package manager is pinned in package.json), Node 20+, the Rust toolchain (only for tauri commands), Java 21 and Android Studio for tauri:android. mise.toml pins the toolchain versions if you use mise.

pnpm install
pnpm dev                  # Astro + Svelte at http://localhost:4321
pnpm tauri dev            # Native desktop shell (auto-spawns pnpm dev)
pnpm tauri:android        # Android dev shell

On Windows and Linux, pnpm tauri dev / pnpm tauri build first download and checksum-verify a trimmed FFmpeg sidecar into src-tauri/binaries/ (run pnpm fetch-ffmpeg to do it manually). The first Tauri build therefore needs network access.

To test the dev server on another device on the LAN (phone, TV), set XTREAM_HMR_HOST to your machine's LAN IP so Vite advertises the right HMR host:

XTREAM_HMR_HOST=192.168.1.50 pnpm dev

Tests run with Vitest (pnpm test); ~28 suites in tests/ cover the parsers, serializers, catch-up math, codec hints, custom playlists, backup, and the playback proxies. Lint with ESLint flat config (pnpm lint / pnpm lint:fix); no Prettier. TypeScript is in strict mode (tsconfig.json extends astro/tsconfigs/strict); the @/* alias maps to src/*.
