Rosalind is a genomics engine written in Rust that runs whole-genome read alignment and variant calling pipelines on a laptop. Supports BWT/FM-index alignment, coordinate-sorted BAM output, germline and somatic variant calling to VCF, with byte-for-bit reproducible outputs. Extensible via Rust trait plugins and Python (PyO3) bindings, ideal for bioinformaticians needing reproducible pipelines.
