I have forked and published sbt-revolver with experimental Scala Native support – running long-lived Scala Native processes in the background directly from your sbt build.
Things like HTTP servers and UI (e.g. gtk) apps seem to work.
Also ported sbt 2 support from upstream.

Recording of my talk from Scalar is up.
In the talk, I invite you to a gentle waltz with a 50-year-old sabre-tooth behemoth called C and why Scala should care about learning to communicate with it.

Thought I'd see how sharp the bleeding edge is and converted my Scala Native CLI tool build from scala-cli to sbt2. And it works!
Machine-wide caching works too, great for Github Actions

Anton Sviridov: Tree Sitting will continue until Scala highlighting improves [Scala Days 2025]
In this talk we take a problem – accurate Scala syntax highlighting – and build a microcosm of tools around it, relying on industry-proven Tree Sitter grammars and parsers.
