CJIT

CJIT is a lightweight, open-source “C Just-in-Time” compiler and interpreter developed by the Dyne.org foundation that lets developers treat C source code as a scripting language, compiling and executing it on the fly without the traditional edit-compile-link cycle. Designed for rapid prototyping, live coding, and embedded automation, the tool reads ordinary C files, JIT-compiles them through an embedded TCC (Tiny C Compiler) backend, and immediately runs the resulting native code inside the same process, preserving the language’s full performance while eliminating build delays. Typical use cases range from interactive system administration scripts and hardware-in-the-loop testing to educational demonstrations and dynamic extension of larger applications; because the runtime exposes a simple REPL, programmers can inspect variables, reload functions, and iterate algorithms in real time much as they would in Python or JavaScript, yet remain within the strict semantics and low-level control of ISO C. The program belongs to the Developer Tools / Compilers & Interpreters category, is distributed as a single, dependency-free executable for Windows, Linux, and macOS, and exposes a minimal C API so it can be embedded in games, plug-ins, or firmware loaders. Version 0.18.2, the third public release, improves 64-bit Windows compatibility, adds thread-local storage support, and ships with a handful of cross-platform examples that show how to embed CJIT as a scripting engine inside a host application. Earlier iterations (0.16 and 0.17) laid the groundwork for modular bytecode caching and safer memory sandboxing, progress that the Dyne.org foundation continues to refine in forthcoming builds. CJIT is available free of charge from get.nero.com, where downloads are served through trusted Windows package sources such as winget, always supply the newest build, and support unattended batch installation alongside other applications.
