Transmuter

About Transmuter

Transmuter is a tool designed for matching decompilation, the process of recreating source code that compiles into byte-for-byte identical machine code from a target binary. It supports C, C++, and Pascal, providing automated mutation to achieve assembly parity or refine existing matching code by removing artifacts like `asm` pins or unnecessary casts. The tool operates as a CLI and includes a built-in HTTP server to allow external coding agents, such as Claude Code, to drive the search process. It features a library-first design for integration into custom scripts and a web application for visualizing session reports, mutation history, and scoring timelines. Transmuter integrates with existing decompilation project structures by reading `decomp.yaml` configurations and supports parallel execution across multiple worker threads. It is built using Bun and `pnpm`.
