Cobalt is a free, open-source web tool for downloading media content from popular online platforms. Users simply paste a link from a supported service and cobalt extracts the media file for direct download. The platform supports a wide range of social media and video hosting services including YouTube, Twitter, Instagram, TikTok, Reddit, and many others. Key features include the ability to remux videos into different container formats without re-encoding, auto audio muting for specific platforms, and customizable download quality settings. All processing happens server-side with no user data stored between sessions, ensuring privacy. The interface is minimal and ad-free, designed for speed and simplicity. Cobalt offers customizable themes to match user preferences. The project is community-driven and fully open-source, with its code available on GitHub for transparency and contribution. Cobalt is ideal for content archivists, researchers, and anyone who needs to save online media for offline viewing or reference purposes.
