cobalt is a media downloader built around one idea: paste a link, get the file, and move on. It has no ads, trackers or paywalls, and it aims to stay simple and efficient rather than pushing accounts or extras.

What is in the project

• An API built with Express.js
• A web app built with SvelteKit
• Shared packages and documentation covering how to run and protect your own instance

Self-hosting

There is no public pre-hosted API, so the maintainers recommend deploying your own instance, ideally with Docker Compose. Their guides explain environment variables, API usage and how to protect a public instance.

Responsible use

cobalt describes itself as working like a proxy that never caches content, and says it only handles freely accessible public media. The end user is responsible for what they download and how they use it.
