It's fast, friendly, and doesn't have any bullshit that modern web is filled with: no ads, trackers, or analytics.
Paste the link, get the video, move on. It's that simple. Just how it should be.

cobalt API

cobalt has an open API that you can use in your projects for free.
It's easy and straightforward to use, check out the docs and see for yourself.
Feel free to use the main API instance (co.wuk.sh) in your projects.

Host an instance yourself

Requirements

• Node.js 18 or above
• git

Setup script installs all needed npm dependencies, but you have to install Node.js and git yourself.

1. Clone the repo: git clone https://github.com/wukko/cobalt
2. Run setup script and follow instructions: npm run setup
3. Run cobalt via npm start
4. Done.

You need to host API and web app separately since v.6.0. Setup script will help you with that!

Ubuntu 22.04+ workaround

nscd needs to be installed and running so that the ffmpeg-static binary can resolve DNS (#101):

sudo apt install nscd
sudo service nscd start

Docker

It's also possible to run cobalt via Docker. I highly recommend using Docker compose.
Check out the example compose file and alter it for your needs.

cobalt is my passion project, so update schedule depends solely on my free time, motivation, and mood.
