BrontoSource offers an automated source‑to‑source refactoring platform that rewrites C and C++ code to modern equivalents, such as replacing standard containers with high‑performance alternatives or converting C loops to idiomatic Rust. The rule‑based engine runs in the background at enterprise scale, integrating with tools like Compiler Explorer to preview changes and fit into CI pipelines, helping engineering teams reduce manual effort, technical debt, and migration risk.

Problem
Maintaining large C and C++ codebases requires frequent refactoring for version upgrades, performance tuning, and bug fixes, which is labor-intensive and prone to human error. Teams often lack automated tools that can safely apply modern language idioms and library replacements across millions of lines of code.
Solution
BrontoSource provides an automated source‑to‑source refactoring platform that rewrites C and C++ code to modern equivalents without manual intervention. The tool parses the original code, applies rule‑based transformations—such as replacing standard containers with high‑performance alternatives or converting C loops to idiomatic Rust—and emits clean, compilable output. Refactoring runs in the background, allowing developers to continue other work while the system updates the codebase. Results can be previewed and integrated via the Compiler Explorer interface, enabling seamless adoption in existing CI pipelines. The platform is designed to scale to enterprise‑size repositories, ensuring consistent code quality and reducing technical debt.
Target Audience
Primary customers are engineering teams managing large C/C++ codebases—such as enterprise software vendors, embedded systems developers, and organizations undertaking language migration projects—who need reliable, automated refactoring at scale.
Features
- Rule‑based transformation engine that upgrades legacy C++ constructs to modern libraries (e.g., std::unordered_map to absl::flat_hash_map) and converts C code to Rust equivalents
- Automatic handling of API changes, type adjustments, and idiomatic language patterns while preserving program semantics
- Scalable processing capable of refactoring hundreds of millions of lines of code across monorepos
- Integration with Compiler Explorer for instant online testing and visualization of before‑and‑after code
- Configurable transformation pipelines that can be customized for specific project standards or migration goals
- Continuous background execution that minimizes disruption to developer workflows
