Open-source alternatives to Runtime

Object-reflector is a Python object reflection library and dynamic attribute access tool. It functions as an object property extractor designed to retrieve values from an object's internal state and inheritance hierarchies during runtime. The library provides the capability to access and extract private, protected, and inherited object attributes. This allows for the inspection of internal properties regardless of their visibility. The project covers domains including software debugging workflows, automated testing utilities, and general Python runtime reflection to analyze object properties

Haxe is a statically typed, multi-target programming language and open-source compiler toolkit that translates a single codebase into native executables and scripts for JavaScript, C++, C#, Java, Python, Lua, PHP, and Flash targets. It provides a unified type system with automatic type inference, a compile-time macro system for code transformation and generation, conditional compilation directives, and a static analysis engine that enforces null safety and eliminates dead code to produce smaller, safer outputs. The language is supported by the HashLink virtual machine, which executes platform

c3c is the compiler for the C3 programming language, transforming source code into executable binaries, static libraries, or dynamic libraries using an LLVM backend. It implements a system based on result-based error handling, scoped memory pooling, and a semantic macro system. The compiler provides first-class support for hardware-backed SIMD vectors that map directly to processor instructions and enables runtime polymorphism through interface-based dynamic dispatch. The project covers a broad set of low-level capabilities, including manual and pooled memory management, inline assembly inte
