Cursor Agent (Cursor AI)

Codex (OpenAI)

Gemini CLI (Google)

GitHub Copilot CLI (GitHub)

OpenCode (open‑source)

Qwen Coder (Alibaba Tongyi)

Aider (open‑source AI editor)

Detects agents present in PATH, runs locally without API keys, reuses existing CLI sessions.

Skill templates

75 composable templates produce output for nine scenarios: magazine editorials, keynote decks, résumés, posters, Xiaohongshu cards, tweet cards, web prototypes, data reports, Hyperframe videos. Each template includes an example.html file.

Underlying design system is nexu-io/open-design (≈40 k stars, 200+ contributors).

Roblox‑Hub‑2026: Resource hub for Roblox game developers

GitHub ⭐ 520, MIT License. Aggregates Lua tools, testing utilities, performance monitors, and reference material for Roblox development.

Tool categories

Game Analysis : hierarchy browser, object inspector, property viewer

Performance : FPS tracking, memory monitoring, ping detection

Input Testing : keyboard, mouse, virtual input testers

Positioning : coordinate recorder, teleport presets, waypoint system

Camera : free‑camera controller, zoom options, view tools

References : API cheat‑sheet, common patterns, best practices

Quick start

git clone https://github.com/trong776/Roblox-hub.git
cd Roblox-hub

Project layout: tools/ contains Lua utilities, docs/ provides API references, examples/ demonstrates usage.

tiny‑world‑builder: Lightweight browser‑based virtual‑world builder

GitHub ⭐ 462, open source. Single‑file HTML application (~16 k lines of vanilla JavaScript) that runs entirely in the browser using Three.js r128 without a backend.

Core features

Terrain editing : eight terrain types (grass, land, mud, water, lava, sand, snow); height adjusted with R / F keys.

Construction & decoration : 26 props (houses, trees, fences, stones, bridges); crops (corn, pumpkin, carrot, sunflower, wheat); animals (cows, sheep).

Smart layout : crops auto‑place on land, bridges auto‑place over water, fences auto‑connect, houses merge into L/T/+/U shapes.

Interaction controls

Place: click a cell

Erase: press E then click or select eraser tool

Orbit view: drag

Zoom: scroll wheel

Switch view: press P or I (isometric → smooth → perspective)

Deployment

# Development
npm run dev   # http://localhost:3000/tiny-world-builder
# Production build
npm run build   # deploy the dist/ folder to Vercel, Netlify, etc.

Technical highlights

world[x][z]

stores terrain, items, and layers per cell. cellMeshes['x,z'] holds Three.js 3D meshes for rendering. setCell(x, z, opts) is the single entry point for state changes; it updates the data structure and rebuilds meshes.

Supports AI‑generated mode, multiple local saves, and weather/time/cloud decorations.
