Fidan

Fidan is for people who are tired of choosing between Python-level ergonomics, Rust-level ceremony, and C++-level legacy drag. You get interpreter, JIT, Cranelift AOT, and LLVM AOT in one coherent toolchain, with real concurrency, direct native interop, tracing, replay, and AI-assisted explain, fix, and improve workflows that belong to the product instead of sitting beside it.
