OmniLink Downloader

Overview

OmniLink is a self-hosted, lightweight, and memory-efficient media downloader designed to strip away intrusive ads and trackers. It supports YouTube, TikTok, and Instagram video downloads through a clean Vuetify dashboard powered by a high-performance FastAPI streaming backend engine.

To bypass aggressive anti-scraping blocks sustainably without getting your IP banned, OmniLink employs an architecture that extracts and forwards ephemeral session strings directly via a companion browser extension—retaining total privacy with zero data storage.

Core Features

• Multi-Platform Support: Downloader pipelines built cleanly for YouTube, TikTok, and Instagram Reels.
• Async Threaded Pipe Streaming: Offloads blocking read/write streams to background OS worker threads (os.pipe), protecting your backend API from 500 crashes and out-of-memory errors under heavy traffic.
• Smart Dual-Environment Handling: Automatically targets native desktop Chrome browser profiles while building locally, then shifts cleanly to client extension authentication when pushed live.
• Privacy-Centric Architecture: No cookies or session identifiers are ever preserved, tracked, or cached on the server.
• Built-In Monetization: Native UI placeholder integration directly wired to your Buy Me a Coffee page to fund future scaling.
