Incremental C-to-Safe-C Migration Toolkit

C6/10May 20, 2026
WhatA source-to-source transformation tool that progressively rewrites unsafe C patterns (raw pointer arithmetic, unchecked casts, manual memory management) into bounded, well-defined equivalents while preserving ABI compatibility.
SignalThe discussion reveals a tension between developers who know C's UB model is broken and those who resist wholesale rewrites to Rust — there is clear appetite for a middle path that makes existing C codebases safer without abandoning the language or the enormous investment in existing code.
Why NowGovernment mandates (CISA memory-safety roadmap) are creating compliance pressure on C codebases that cannot practically be rewritten in Rust, and LLVM's source-transformation tooling has matured to make automated, semantics-preserving rewrites realistic.
MarketDefense contractors, embedded systems vendors, and infrastructure companies with millions of lines of legacy C — multi-billion dollar TAM. No direct competitor offers automated incremental migration; current options are full Rust rewrites or manual auditing.
MoatProprietary transformation rule engine trained on real-world C codebases, plus switching costs once an organization adopts the tool's bounded-C dialect across their build system.
