Model Context Protocol SDK for building structured, production-grade AI systems.

Ultra-lightweight, zero-bloatware Instant Replay & Game Clipping tool for Windows built with Rust & Tauri v2. Captures rolling GPU buffers (NVENC, AMF, QSV) via DXGI Desktop Duplication with sub-50ms MP4 flush, WASAPI audio loopback, and zero background telemetry.

petslike but with better optimization, and lower latency

CEBS (C++ Ergonomic Build System) — A zero-config, blazingly fast, multi-threaded C++23 build system treating modules as first-class citizens. pretty fast too

High-performance, zero-copy L2–L4 network signal extractor built with Rust & eBPF(CO-RE). Captures packets via XDP ingress, transforms data into 64byte frames, and delivers to userspace via lock-free per-CPU ring buffers with sub-microsecond jitter. Designed for 100 Mpps line-rate critical protocols. Post-init heapless, multi-threaded architecture.

Stream-first HTTP client for Go. Efficient, zero-buffer streaming for large HTTP payloads.

Simple Header Arbitrary Data Exchange protocol

A highly optimized, safe C/C++ LIFO stack allocator. Features an inverted bi-directional buffer layout, dynamic metadata scaling, XOR-hardened markers, and zero-dependency bare-metal support.

Dynamic Array implementation focused on low overhead in C.

Ultra-low overhead PEP 669 instruction-level tracer and telemetry engine for Python 3.12+. Built with Rust for hardware cycle accuracy (TSC) and dynamic de-instrumentation.

Stop guessing, measure. JitProfiler is an engine-native LuaJIT sampling profiler for STALKER Anomaly: one capture covers the whole modpack and names the mod behind each hot script. CPU, memory, GC, instrumentation, and callbacks profiling; SpeedScope flamegraphs; engine-C entry points mapped for Optick. Low-overhead, save-safe.
