What happens when you push to git.sr.ht, and why was it so slow?

Hosted git repositories

• Annotate your source with links, docs, references, etc
• Public, private, and "unlisted" repositories
• Fine grained access control, including access for users without accounts
• First-class Mercurial support also available

Sourcehut has been a breath of fresh air for me. I finally have a code hosting solution that lets me focus on being productive.

Powerful continuous integration

• Runs fully virtualised builds on various Linux distros and BSDs
• Submit ad-hoc jobs without pushing to your repository
• Post-build triggers for email, webhooks, etc
• Log in with SSH after build failures to investigate further

This CI experience is leagues ahead of all others. Resubmitting builds and SSH'ing in is saving me multiple hours.

Mailing lists & code review tools

• Patch review tools on the web
• Threaded, searchable mail archives
• Tools for working with third party mailing lists

What I like about Sourcehut is that it just connects tools together. I think this is an example of Drew [founder of Sourcehut] at his most brilliant.
