9 AI Coding Tools tools (8 free)
9 AI Coding Tools resources, picked out of 10 liked tweets, from creators like @nutlope, @rauchg, @PratikKadam_. 8 of them are free, freemium or open source.
Inspo is a curated archive of over 800 production websites and 2,300+ screen captures that functions as a reference layer for AI coding agents. Through a simple Model Context Protocol (MCP) server, agents like Claude Code, Codex, and OpenCode can search real-world designs, canonical components, color schemes, and per-site DESIGN.md files mid-generation. It can also be browsed manually via the web interface to discover UI inspiration.
agent-skills is Vercel's official collection of packaged rules and instructions designed for AI coding agents like Claude Code and Cursor. It equips agents with decades of production engineering knowledge, including prioritized React and Next.js performance optimizations, web design guidelines, and one-click Vercel deployment scripts. Agents automatically call these structured markdown guidelines and scripts when performing code reviews, refactoring, or auditing UI.
A reference list of 20 AI-assisted software builders and coding assistants compiled by Pratik Kadam in late 2024. It covers a broad cross-section of tools ranging from full IDE forks and coding agents to prompt-to-app web builders. It serves as a starting directory to compare different approaches to generative software development.
This Claude Code skill extracts exact timing, easing, and stagger parameters from video references like X clips, Dribbble shots, or screen recordings. It uses ffmpeg and yt-dlp to dissect frames instead of guessing transitions, then writes the corresponding Framer Motion implementation. It supports both timeline-driven and interaction-driven animations.
Hallmark is an open-source design skill and rule set for AI coding assistants like Claude Code, Cursor, and Codex. It prevents models from defaulting to generic AI templates by applying macrostructures, 21 distinct themes, and 57 anti-slop test gates to ensure each generated site looks unique and intentional.
A practical guide explaining Model Context Protocol (MCP) support in Cursor and how to connect AI to external environments. It outlines real-world workflows like querying production databases, managing GitHub repositories, and debugging console errors directly in the editor.
One is a macOS desktop app and iOS companion that consolidates multiple AI coding agents into a single toolbar and unified inbox. It collects questions and completion statuses from tools like Claude Code, Codex, and OpenCode, allowing you to answer or delegate tasks using voice or keyboard shortcuts without context switching. It also supports managing agents running on remote Linux servers.
OpenSpec adds a Git-tracked Markdown specification layer to codebases so coding agents understand intent, requirements, and constraints before generating code. It structures changes into proposals, designs, and spec deltas, merging updates back into living documentation once features ship. This helps teams align AI agents across sessions and shift focus from heavy code diff reviews to plan reviews.
An open-source marketplace that bundles dozens of specialized AI agents, orchestrators, skills, and dev tools across multiple coding environments. It formats and deploys these modular agent setups across platforms like Claude Code, Cursor, Codex, OpenCode, and GitHub Copilot with isolated context windows.
