Wow, you heard about Pijul years ago then.
I believe it is production-ready, in the sense that there hasn't been any real bug in months. I'll remove the "beta" label when more people use it.
One thing that isn't production-ready is nest.pijul.com, but mostly for lack of funding: that platform uses the CRDT nature of Pijul to replicate all the repositories in different datacenters, but the machines it runs on are somewhat undersized, and the PostgreSQL databases don't like that very much.
But you don't need that to use Pijul, a simple SSH server works fine.
