Commercial software, built by Leafscale.
Precision, performance, and a bias toward owning your own workflow. Two products today — a private forge, and a systems language.
Private forge
Isurus
A private, dedicated forge for Git, Mercurial, and Fossil, delivered as a fully dedicated, Leafscale-managed tenant — your code never shared, never mined.
- Git, Mercurial, and Fossil, all first-class
- Issues, PRs, CI/CD, releases, SSO, and analytics in one forge
- Your own isolated tenant with data-residency control
active object Counter
value: int
exclusive proc incr()
self.value = self.value + 1
end incr
shared fn get() -> int
return self.value
end get
end Counter
Systems language
Reef
A systems language pairing Oberon’s Active Objects with the expressiveness of Ruby and Crystal, compiled to native code — from userland to bare metal. Open source under Apache-2.0.
- Active Objects: data-race freedom for object state, at compile time
- Compiles through C and GCC/Clang — no VM, no runtime dependency
- A working compiler, runtime, and 138-module standard library
