A statically typed, ahead-of-time compiled programming language with first-class hot-reloading for live applications.
Mun is a statically typed, ahead-of-time compiled programming language designed for high-performance applications with built-in hot-reloading. It allows developers to modify code in a live application without restarting it, significantly speeding up iteration cycles. The language uses LLVM for compilation, ensuring native execution speed while providing strong type safety and IDE integration.
Developers working on applications that benefit from live coding and rapid iteration, such as game developers, simulation engineers, and tool creators who need to tweak logic without downtime.
Mun uniquely combines the performance and safety of AOT compilation with first-class hot-reloading, a feature typically found in interpreted languages. This allows for both fast development iteration and production-ready performance, making it ideal for projects where live updates are critical.

Mun compiles ahead of time to eliminate runtime errors, enabling powerful IDE tooling and immediate feedback, as stated in the README's feature list.
Hot-reloading is built into the language from the ground up, allowing live code changes without application restarts, which is core to its rapid iteration philosophy.
Uses LLVM for optimization, ensuring native execution speed, and hot-reloading overhead can be disabled in production builds for maximum performance.
Supports compiling to all target platforms from any supported compiler platform, facilitating easy multi-platform development.
Building from source requires Rust and LLVM 14, which adds significant setup complexity compared to languages with simpler installation processes.
As a new language, Mun lacks the extensive libraries, frameworks, and community support of established languages, making it harder for complex projects.
Pre-built binaries are unsigned and milestone releases are unsupported, indicating the language is still in development and not yet stable for critical use.
