the cli.rs domain is expired!
PSA to all projects hosting their cli tools at a [subdomain].cli.rs url: last week the cli.rs registration expired (whois) and all pages have been offline since.
The domain registrant, @zackify (/u/coding9) has not responded to the github issue on the matter, and seems to have distanced from rust anyway for writing vibe coding blogs (https://zach.codes)
You may want to migrate to github pages or alternatives. Perhaps an official rust entity can pick up the domain and setup a more consistently-maintained service for rust utilities, like how docs.rs is.
