duy90utc528/repo-publication-audit (★74 · Python) A small, dependency-free preflight checker for repositories about to become public. It catches common accidental disclosures and reports whether a project has the basic community files expected of an open-source repository. It is intentionally conservative: findings are prompts for review, not proof
vuphongle/oss-pr-reviewer (★73 · TypeScript) AI-powered CLI for reviewing GitHub pull requests, detecting potential bugs, security risks, regressions, and missing tests, with structured Markdown reports for open-source maintainers.
phungkaizen/maintainer-autopilot (★66 · JavaScript) Tiếng Việt AI can write the code. Who makes sure it is safe to merge? Maintainer Autopilot is a local-first CLI for turning maintenance tasks into resumable, auditable AI coding pipelines with a single-writer lock, explicit repair lineage, read-only review, deterministic verification gates, and optional GitHub PR/CI promotion.
thiientv/godmode (★62 · Python) English | 简体中文 Your coding agent already knows how to code. Godmode teaches it how to engineer. Godmode is a composable catalog of engineering workflows and expert
overflowy/zhist (★21 · Go) A shell history tool for zsh, written in Go. It records every command with its working directory and exit status. It replaces the zsh history file as the persistent store.
xiangyanghua-22/codex-hooks-doctor (★21 · TypeScript)

MaincodeHQ/from-tin-to-tokens (★16) Building an LLM Inference Stack from Scratch in Rust. A free textbook on inference-stack engineering. It covers the whole stack, from the driver interface where you write ioctl structures by hand to an HTTP endpoint serving thousands of concurrent users: attention kernels, a paged KV cache, a scheduler, multi-GPU collectives, a quantisation pipelin...
matrixarkai/matrixcache (★7 · Rust)
matrixcache is a standalone, Rust-native multi-tier cache library extracted from TemporalStore and reusable by any Rust service. It manages a hot in-memory (DRAM) tier, a persistent-memory-like resident tier, and an SSD tier, with admission control, cross-tier eviction, read-through refill, pinned handles,
matrixarkai/matrixraft (★7 · Rust) MatrixRaft is the TemporalStore-owned Rust Raft readiness and parity contract library. It is intentionally small: the crate owns the stable public contract for Raft semantic requirements, readiness evidence, and parity reports, while TemporalStore owns the storage runtime, data-node integration, and metaserver
rust-lang/rust (★115,486 · Rust) src=" width="50%"> [Website][Rust] | [Getting started] | [Learn] | [Documentation] | [Contributing] This is the main source code repository for [Rust]. It contains the compiler,
vite — v8.2.1
A build tool and dev server for modern web projects. Starts instantly (no bundling in dev), uses native ES modules in the browser, and bundles with Rollup for production. The replacement for webpack in most new projects.
esbuild — v0.28.2
A JavaScript and TypeScript bundler written in Go. Extremely fast — 10-100x faster than webpack or Rollup. Used as the engine inside Vite and many other tools. Good for simple bundling; less configurable than webpack.
turbo — v2.10.9
A build system for JavaScript/TypeScript monorepos. Caches task results so you only re-run what changed. Built by Vercel. Speeds up CI and local builds in large codebases with multiple packages.
biome — v0.3.3
A single tool that replaces both ESLint and Prettier. Formats and lints JavaScript, TypeScript, JSON, and CSS. Written in Rust, so it runs much faster than the JS-based tools it replaces.
bun — v1.3.14
A JavaScript runtime, package manager, bundler, and test runner in one. Faster than Node.js at most things. Drop-in compatible with most Node.js code. Written in Zig.
vitest — v4.1.10
A unit testing framework built specifically for Vite projects. Uses the same config as your Vite build, runs tests in the browser environment, and is significantly faster than Jest.
oxc — v1.0.1
A JavaScript/TypeScript toolchain written in Rust — parser, linter, formatter, transpiler, bundler. The project behind the oxlint linter. Faster than most existing tools by a large margin.
rspack — v0.1.1
A webpack-compatible bundler written in Rust. Drop-in replacement for webpack with the same config format, but much faster. Built by ByteDance (TikTok's parent).
wrangler — v4.122.0
The CLI for deploying and managing Cloudflare Workers — serverless functions that run at the edge in Cloudflare's global network. Also manages KV storage, Durable Objects, Pages, and R2.
drizzle-orm — v0.45.2
A TypeScript ORM that lets you write SQL-like queries in TypeScript with full type safety. Lightweight, no code generation step, and closer to raw SQL than ORMs like Prisma.
