I got "Error Progress bar not found" visiting your https://pbar.io/Y8yg3BG link. However, there are no comments yet, so that might explain it. So this is a service you provide.

I must admit that idea behind this project is nice, but I'm not going to get dependent on someone else's infrastructure (and I think I'm not the only one thinking that way), can I host it myself or is the source not available? I don't see any links to sources or github, so decided to just ask here (and to also make the 1st comment here to see if your link would work now).
