Stream Mate - Social Media Downloader & Streaming App
Stream Mate is a feature-rich, privacy-focused mobile application built with Flutter that enables users to download videos, photos, reels, and audio from major social media platforms including YouTube, Instagram, TikTok, Twitter/X, Facebook, and Threads. Beyond downloading, the app doubles as a full-featured media streaming platform with an in-app browser, movie discovery section, background audio playback, and an offline media library — all without requiring platform API keys by leveraging client-side extraction engines.
