Top ENGINEERING GitHub Repositories & Tools (2026)

An iPhone battery, charging and thermal instrument built on private iOS APIs — real charger watts, what actually reaches the cell, all 30 temperature sensors, and the USB-PD handshake.

Skill that audits and rewrites content to remove AI writing patterns. Use it with your favorite agents including Claude Code, OpenClaw, Codex, and Hermes.

Apache Airflow - A platform to programmatically author, schedule, and monitor workflows

AirPods liberated from Apple's ecosystem.

Official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.

Forward deployed engineering skills for AI coding agents.

Bounded, evidence-driven SKILL.md evolution under frozen evaluation and safety contracts.

Unbounded context. Memory that manages itself. One session, for life. The hippocampus for coding agents, part of CortexKit.

Free and Open Source Reverse Engineering Platform powered by rizin

DEX → Java decompiler in Rust — fast, progressive analysis, bilingual CLI

Your agent invents things because it has no memory, and can't touch your database because it has no arms. rsc is the meta-harness that gives it both, plus the trade to know the job and the reflexes to not break your repo. For Claude Code, Codex and 15 more.

A sandbox for the third-party APIs you depend on. Built from the provider's spec, it fails on purpose, and it replays the exact failure production hit.

The open-source AI workbench for scientific research

An orchestration platform for the development, production, and observation of data assets.

Plugin for JADX to integrate MCP server

OpenChoreo is an internal developer platform for Kubernetes

LeanCTX — Context Intelligence for AI systems.

Drop-in Apache Spark replacement written in Rust, unifying batch processing, stream processing, and compute-intensive AI workloads.

An AI Gateway, registry, and proxy that sits in front of any MCP, A2A, or REST/gRPC APIs, exposing a unified endpoint with centralized discovery, guardrails and management. Optimizes Agent & Tool calling, and supports plugins.

vCluster creates tenant clusters: fully isolated environments delivered as managed Kubernetes, or as the foundation for Slurm, Ray, Run:ai and inference clusters. Each gets its own API server, CRDs and RBAC, and runs on an existing cluster or standalone on bare metal. CNCF Certified Kubernetes.
