This is the closest I'm finding! CI, web-based ticket submission for anyone with a site-wide login, static hosting, good price... web-based patching would be nice, good to see it in development.
Some honest feedback: 10 minutes of searching and reading left my ADHD brain confused about pricing and quotas. It doesn't have any numbers for what I'm getting for $4/8/12/mo. And it took me 3 reads of that page to notice that the tiers are not actually the standard tiers, but pay-what-you-can. I first jumped to the prominent table then hunted for the fine print for the quotas, didn't even the read "there is no difference between the subscriptions besides price." Then read it but my mind thought "OK, all features are available to all tiers, but at what quotas?" A normal VC backed company might hide this because they're trying to pull one over on you...
Also, "Sourcehut’s public alpha... What we consider an alpha passes for a production-ready system to some." That's a choice, I get it, but it makes me feel like I'd be jumping from one unreliable platform to another. Maybe link to your uptime? (And the real github uptime side by side :P)
Because another honest thought: unlike GitLab, which pretty much has the same shaped features and affordances that you can one-click import and things mostly work, this would be a pretty breaking change to that would be difficult to revert. I do see full data autonomy is on the roadmap too though.
