Claude Open Source Tools
Claude refers to a family of large language models used for tasks such as writing, analysis, coding, and conversational assistance. Tools built around Claude help people connect these models to applications and data, automate repeatable work, and incorporate AI into software development. They can also make model interactions easier to manage, customize, or combine with other services.
Open source tools in this area include API clients, coding assistants, agent frameworks, workflow integrations, and utilities for managing prompts or context. When choosing one, consider its license, maintenance activity, model and service requirements, security practices, and compatibility with your existing tools. These options can be useful to developers, teams, and individuals who want to build AI-enabled workflows or tailor how they use Claude.

claude-video: Empowering Claude to Watch and Analyze Any Video Content
The claude-video repository provides a powerful tool, `/watch`, enabling Claude to process and understand video content. It automates the download, frame extraction, and transcription of any video, feeding this rich data to Claude. This allows Claude to answer questions and provide insights grounded in what it has actually seen and heard.
Autoresearch: Autonomous Iteration for LLM-Powered Code Improvement
Autoresearch is a powerful GitHub repository that transforms large language models like Claude Code, OpenCode, and OpenAI Codex into relentless improvement engines. Inspired by Karpathy's autoresearch, it enables autonomous, goal-directed iteration, following a "Modify, Verify, Keep/Discard, Repeat" loop to achieve compounding gains across various domains. This project offers a structured approach to automate development, security, and operational tasks with AI.
claude-code-codex-bridge: Sync Your Claude Code Setup with Codex
The `claude-code-codex-bridge` is a Python tool that automatically synchronizes your Claude Code setup, including plugins, skills, agents, and commands, with Codex. This one-way bridge ensures that any changes made in Claude Code are reflected in Codex, keeping both environments equally effective. It streamlines the management of AI coding tools by allowing you to configure once and deploy across both platforms.
AnythingMCP: AI-Empowered Gateway for Custom Claude, ChatGPT, Gemini Connectors
AnythingMCP is a self-hosted, open-source AI-empowered gateway that transforms existing APIs, databases, and MCP servers into custom connectors for leading AI models like Claude, ChatGPT, and Gemini. It enables no-code integration of REST, SOAP, GraphQL, and SQL sources into the Model Context Protocol, featuring robust authentication, access control, and audit logging. The platform also includes over 175 pre-built adapters for common services, simplifying complex integrations.
