Sky — an Elm-inspired language that compiles to Go. Hindley-Milner types, server-driven UI (Sky.Live), single binary output. - anzellai/sky
Summary

Sky v0.15 compiles functional ML-style code with Hindley-Milner inference to single Go binaries, auto-generating FFI bindings for any Go package. Features server-driven UI (Sky.Live), auto-TCO eliminating stack growth, and a console with Prometheus metrics. A 76k-symbol Stripe benchmark tree-shakes to 18% of original lines, while type-directed lowering closes long-standing parametric record alias bugs.

Key Takeaways
  • Evaluate Sky v0.15 as an alternative for building AI-friendly, fullstack services with strong type safety and Go's deployment simplicity.
Why it matters

For a solution architect, Sky offers a statically-typed, pure-functional approach to building backend services that leverage Go's ecosystem without manual glue, plus built-in server-driven UI and observability, reducing architectural complexity.
