OpenRig: Turn Claude Code and Codex into a Persistent Agent Team You Define in YAML
[Github][⭐ 6,161]OpenRig is an open-source "harness for your harnesses." In plain terms: it takes the AI coding assistants you already run in scattered terminal windows and turns them into a named, long-lived team that actually works together. You describe the team in YAML, run one rig up command, and Claude Code plus Codex agents boot up in their assigned seats. Two things stand out. First, mixing providers — Claude Code and Codex can sit in the same rig as colleagues, and OpenRig can even discover and adopt tmux sessions you already have running. Second, persistent identity: every seat keeps a stable address and role, so after a reboot you can snapshot and restore the whole team instead of rebuilding it by hand. With 5,000+ stars on GitHub, it's a serious option if you'd rather talk to a lead agent about the outcome you want than babysit a wall of terminals.

HyperFrames: Write HTML, Render Video — A Deterministic Video Engine Built for AI Agents
[Github][⭐ 59,216]HyperFrames is HeyGen's open-source framework that turns HTML into an MP4 video. It solves a very specific problem: letting AI coding agents make videos on their own — agents are already great at writing HTML and CSS, so now those files can be rendered into frame-accurate, repeatable clips. Two standout features: it ships 21 skills so tools like Claude Code, Cursor and Codex can act on a plain prompt such as "make me a 10-second product intro", and rendering is deterministic — the same input always produces the same frames, which is perfect for automation and CI. Getting started is easy: npx hyperframes init, then preview and render, with no build step at all.

cursor/plugins: Cursor's Official Plugin Marketplace That Gives Your AI Coding Agent Superpowers
[Github][⭐ 10,403]cursor/plugins is Cursor's official plugin marketplace — a single repo that collects ready-to-use add-ons for the AI code editor. The problem it solves: an AI agent is smart but isolated, locked out of your email, GitHub, Salesforce, or browser. These plugins wire it in. Highlights: 80+ official plugins spanning developer tools (Thermos branch audits, Orchestrate parallel cloud agents, PR Review Canvas) and third-party integrations covering Gmail, GitHub, Playwright, Slack-adjacent Teams, Salesforce, Coinbase, Robinhood and more. Each plugin is a self-contained folder with its own manifest, so you can browse, install, or copy just the piece you want. MIT licensed and refreshed continuously by Cursor.

Agent Reach: Give Your AI Agent Eyes to Read and Search the Whole Internet — One CLI, Zero API Fees
[Github][⭐ 94,178]Most AI agents can write code and edit docs, but ask them to fetch something from the web and they go blind — YouTube subtitles are locked, Twitter's API costs money, Reddit throws 403s, and XiaoHongShu demands a login. Agent Reach is a single CLI that fixes all of this at once. Copy one install sentence to your agent and minutes later it can read tweets, search Reddit, summarize YouTube videos, and browse Bilibili — with zero API fees. Its killer feature is a "primary + backup" backend list for every platform: when a site changes its defenses, the project just swaps the route and you feel nothing. It works with any command-line-capable agent like Claude Code, Cursor, or Windsurf, plus a built-in agent-reach doctor health check.

text-to-cad: Give Your AI Agent CAD Superpowers and Turn Plain Words into Real 3D Models
[Github][⭐ 18,481]text-to-cad is a plugin that hands your AI agent CAD superpowers. Just say what you want in plain English — "make me a phone stand" — and it spits out printable, machinable 3D model files (STEP, STL, 3MF, GLB). It kills the old headache of not knowing how to use professional CAD software: no years of modeling practice, just talk. The really cool part is that it doesn't stop at drawing. It runs design-for-manufacturing checks — wall thickness, overhangs, support volume, sheet-metal and CNC rules — generates dimensioned engineering drawings, and can push your file straight to 3D printing, sheet metal or CNC services. It works with Claude Code, Codex, Cursor, Gemini and Grok, and it's already sitting at 18,000+ stars.

openGym: A self-hosted gym and body-weight tracker where your data lives on your own server
[Github][⭐ 8,045]openGym is a self-hosted gym and body-weight tracker you actually own — no account on someone else's server, no subscription, no ads, no telemetry. One docker compose up and it runs on your own box. It ships with 1,324 exercises with animated demos, weekly routine planning, guided workouts with supersets, drop sets and a rest timer that flags personal records as you lift. Its standout trick is a muscle map that shows where your volume went, what is still recovering, and what has gone untrained. Sign in with passkeys, sync phone and laptop automatically, and import years of history from FitNotes, Strong or Hevy. Your passkey keys never reach the server.
