Cobalt Reviews — Discover what people think of this product.

Cobalt is an open-source media downloader that lets you quickly grab public videos and audio from popular social networks without ads, tracking scripts, or clutter. Paste a link from sites like YouTube, TikTok, Instagram, Twitter, Reddit, Vimeo, SoundCloud, or VK and immediately receive a clean file you can store or share.

Built as a modern Svelte, TypeScript, and JavaScript monorepo, Cobalt includes an API, web interface, and reusable packages that developers can self-host or extend. It behaves like a privacy-respecting proxy, never caching content, and only accessing media that is already publicly available through regular browser tools.

Key highlights:

• Minimal friction: paste a URL and download the media file with no pop-ups or dark patterns.
• Privacy-focused: no trackers, no paywalls, and no user profiling.
• Self-hostable: run your own instance using Docker and environment variables for full control.
• Ethics-first: designed strictly for public content, with clear guidance on responsible usage.

Whether you want a distraction-free way to archive favorite clips or need a reliable backend for media retrieval, Cobalt delivers a streamlined, community-driven experience backed by extensive documentation and active contributors.
