kenny-ngo/wasmjit

wasmjit is a legacy experimental project (over 7 years old) with negligible adoption (51 stars) and zero current velocity. While the concept of running Wasm in kernel space is technically sophisticated—aiming to eliminate context-switching overhead between user and kernel space—this specific implementation has been effectively superseded by two forces: the massive industry consolidation around eBPF for safe kernel-mode execution, and newer Wasm-to-kernel efforts like 'kwasm'. The project's age and lack of updates mean it likely does not support modern Wasm proposals or recent Linux kernel versions. From a competitive standpoint, eBPF is the 'platform' that has already won this niche, making the defensibility of a standalone, unmaintained kernel Wasm runtime nearly zero. It remains a historical reference implementation for how one might approach kernel-space JITing, but lacks any commercial or ecosystem moat.
