What are the alternatives to Graphite these days? Github's stacked PR support is still immature, AFAIK. I would love to see Linear move into this space and start offering both git hosting and stacked PR management.

My team uses git-spice [1], which is client-side only and works just as well as Graphite.

Aviator [2] is also good, and they have a hosted UI with merge queue support as well.
