bamboostrip/Handwriting-simulator (★46 · Python)
把普通文本变成以假乱真的手写体图片：选择一款手写字体、一张信纸背景，程序会按真实的书写习惯排版并施加字距、行距、字号、笔画位移、笔画旋转等多种随机扰动，让每个字、每一页都独一无二。 提供 图形界面（GUI） 与 命令行（CLI） 两种使用方式，核心引擎基于 numpy + scipy 全向量化重写，预览渲染一页约 0.15 秒，实时交互流畅。
LunkiBR/ship-it (★14 · Python) A Claude Code skill that catches the boring-but-important details before you ship a screen or feature. Not a linter for your code — a linter for the product. Login, checkout, billing, empty states, 404s, admin panels: the parts of an app that follow well-known patterns, and that get half-finished anyway because nobody double-checked the borin...
bl4ckr0ss3/knife (★11 · Rust) A reverse engineer's binary Swiss-army knife, in Rust. Parse, triage, and disassemble PE, ELF, and Mach-O from one small binary. No runtime, no services, the target is never executed.
BenRamins/otto (★8 · HTML) Otto is a recipe-driven AI-development workflow assembled from three open-source projects — spec-kit, agent-skills, and Matt Pocock's skills — **without forking, copying,
matonhp5108/Opencodex (★5 · TypeScript) A standalone, Codex-style coding agent that runs entirely inside VS Code. Opencodex allows you to use free models from multiple providers to power your agent. Open a project, pick a provider and a free model, and describe what you want. Opencodex works exactly like an agent like OpenAI Codex.
asutekku/crewmates (★4 · TypeScript) Presence and coordination for several Claude Code sessions working in one project at the same time. Install · Usage · Views · Audiences · Naming · Operating · Internals · Design notes Several Claude Code sessions in one checkout are completely blind to each other. This gives them a roster, names, messages and a memory that outlives the session.
Amey-Thakur/GIT-GUIDE (★4) Every Git and GitHub answer in one place. Type what you want to do. Get the exact commands, what each one does, how dangerous it is, and how to undo it. Open Git Guide · Download the PDF · Ask a question
hetpatel-11/agent-hop (★4 · TypeScript) Search all your coding-agent chats, then resume any session in any agent.
bestdeejay-design/agent-skills (★4 · Python)
Autonomous skill instructions for AI agents: Sisyphus, opencode, and compatible. Each skill is a folder with

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 — v4.120.0
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.
