Is the demo workspace link still available?

No. The demo workspace link is no longer available. Breakcold no longer has a demo environment, and the previous link has been deprecated.

Why is the link still mentioned in the documentation?

The documentation may still reference the old demo workspace link. The team plans to update the documentation to reflect that the demo environment is no longer available.

If you found the link in a help article, that reference does not mean the demo workspace is still available to access.
