Spinel is an open-source AOT compiler that converts Ruby source code to standalone native executables through whole-program type inference and optimized C code generation. The compiler is self-hosting—its backend is written in Ruby and compiles itself to native binary via a three-iteration bootstrap process. Benchmarks show a geometric mean of ~11.6x speedup over miniruby (Ruby 4.1.0dev) across 28 test cases, with individual optimizations yielding up to 86.7x improvement on computation-heavy workloads.
