cobalt hosting in the EU

cobalt: save videos and music from sites like TikTok and SoundCloud through your own download API. On blitz.cloud you install it from the App Store in one click. It gets its own address with HTTPS, and it runs on servers in the EU. You can run it on the free plan, without a credit card.

A self-hosted alternative to y2mate, SaveFrom and yt-dlp

cobalt does the job of y2mate, SaveFrom or yt-dlp, but it is your own copy: your data sits in your app, not in somebody else's account, and nobody changes the price or the rules on you. Self-hosting usually means renting a server and keeping it patched. Here the App Store sets it up and keeps it running.

What it needs

Install it

1. Create a free account and open the App Store in the dashboard.
2. Search for cobalt, or for y2mate, and pick a name. It becomes the address, like cobalt.yourname.blitz.cloud.
3. Click Put it online. The last step lists everything that gets created and how much of your plan it uses.
4. Send a POST to the app's address from your private network with a JSON body like {"url":"..."} and the header Accept application/json.

Good to know

This is the download API without the cobalt website. YouTube and some other sites refuse downloads from servers like ours.

Questions

Can I host cobalt for free?

Yes. The free plan runs it without a card and without an end date. The app sleeps after 30 minutes without visitors, and the next visit wakes it.

Where is my cobalt data stored?

On blitz.cloud's servers in the EU, run by BlitzWorks, a company in Germany. Once signed in, you can download the data processing agreement as a PDF.

Can I use my own domain for cobalt?

Yes, on Pro, or on the free plan by making this one app a Pro app. HTTPS for the domain is set up for you.

Is cobalt backed up?

On Pro its files are copied every night and kept for 30 nights, and you can put them back from the app's page. On the free plan they are not copied, so keep an export of what matters.

How does cobalt get updates?

With automatic updates on, it gets new versions of its version line overnight. If a new version doesn't start, the one before it keeps running.
