FERRITE

Native macOS .NET decompiler

What is it?

Ferrite is a fully native macOS app for inspecting and decompiling .NET assemblies (.dll / .exe). Unlike most .NET tools that run on Mono or Wine, this one is built from scratch with a Rust backend and a SwiftUI frontend — so it feels at home on macOS.

Features

C# decompilation — async/await, generics, lambdas, LINQ, pattern matching
IL disassembly — full ECMA-335 opcode view with syntax highlighting and clickable type references
Assembly browser — sidebar tree: assembly → namespace → type → member
Fuzzy search — Cmd+K across all loaded types and members
Multi-assembly projects — group assemblies into projects that persist between sessions
Drag and drop — drop .dll / .exe directly onto the window
Code export — export the current view in .cs or .h
Fast — memory-mapped I/O and lazy loading keep RAM usage low

Tech stack

The core parsing pipeline is written in Rust (ECMA-335 metadata, PE headers, CLR streams), bridged to Swift via UniFFI. No Electron, no JVM, no Mono — just a native binary.
