c99

Z-Jail is a lightweight Linux sandbox written in C99 with seven defense layers, no external dependencies, and a tiny binary size (~130 KiB), designed for secure code execution in CI, CTF, and lightweight evaluation.

CParseC is a single-header C99 library for parser combinators inspired by Haskell's Parsec, offering zero-copy parsing, no hidden allocations, and SIMD-optimized combinators. It aims to provide a flexible, performant alternative to handwritten parsers and lex/yacc tools.
