Free Claude Code

OpenClaude is an open-source, terminal-first coding-agent CLI for cloud and local model providers. It connects to OpenAI-compatible APIs, Gemini, GitHub Models, Codex, Ollama, Atomic Chat, and other supported backends, providing prompts, streaming output, Bash and file tools, grep, glob, agents, tasks, MCP, slash commands, web search and fetch, and image inputs for compatible providers. The CLI supports guided provider setup with saved profiles, conversation continuation and forking, detached local background sessions, model-specific agent routing, repository maps based on PageRank-ranked code structure, and a headless bidirectional-streaming gRPC server for integrations, CI/CD pipelines, and custom interfaces. A bundled VS Code extension provides launch integration, in-editor chat, provider-aware controls, and theme support. OpenClaude runs on Node.js 22 or newer, is distributed through npm and an Arch Linux AUR package, and can use local inference or remote APIs. Its repository is licensed MIT for the project's modifications and states that it is an independent community project derived from and substantially modified from the Claude Code codebase, without Anthropic affiliation.

Klaat Code is an open-source, terminal-native AI coding agent from KlaatAI. It reads and edits project files, runs shell commands, performs type checks after edits, and asks for permission before risky operations. It supports planning, sub-agents, MCP, hooks, and skills, and indexes projects into a code knowledge graph containing symbols, callers, callees, and semantic-search data for targeted exploration. Its hosted Klaatu-o1 router classifies each request and dispatches it across six model-cost tiers—nano, fast, code, reason, heavy, and titan—rather than using one model for every task. The CLI is a thin client to this service; the repository states that routing decisions, model health tracking, pricing, and the code-graph index run server-side. It supports providers and models including Claude, GPT, Gemini, and DeepSeek, and can be installed with npm.

Codex Router is an independent community project that routes external AI models into the Codex app and CLI, adding providers such as Kimi, DeepSeek, Anthropic, xAI, and GitHub Copilot alongside native models. It provides guided provider authentication, keeps credentials on the local computer, and supports safe migration and rollback of recognized older setups. The project includes a command-line installer and setup flow, an Electron Control Center, a tray or menu-bar application, and a macOS desktop widget; one installation can also serve DeepSeek Harness and Gemini CLI. It supports macOS, Linux, and Windows, and is not affiliated with OpenAI or the other referenced model and platform providers.

Claude Code Templates is a CLI tool and web catalog for configuring and monitoring Anthropic's Claude Code. It provides installable agents, custom slash commands, settings, hooks, skills, MCP integrations, and project templates, which can be selected interactively or installed with commands such as `npx claude-code-templates@latest --agent ...`. The CLI also includes analytics for monitoring development sessions, a conversation monitor with optional Cloudflare Tunnel access, health checks for Claude Code installations, and a plugin dashboard for viewing marketplaces, installed plugins, and permissions. The project aggregates components from Anthropic and community sources, while retaining their stated licenses and attributions; the project itself is licensed under the MIT License.

Everything Claude Code is a Claude Code plugin and toolkit containing configurable agents, skills, slash commands, rules, hooks, contexts, MCP server configurations, scripts, and tests for AI-assisted software development. Its agents delegate tasks such as planning, code review, security review, testing, and build-error resolution. Skills define workflows including test-driven development, security review, continuous learning, and verification; hooks run on Claude Code tool or session events to load and save context, suggest compaction, and evaluate sessions; and rules provide persistent guidance for security, coding style, testing, Git workflow, delegation, and performance. Node.js scripts support Windows, macOS, and Linux and detect a project's preferred package manager from environment settings, project configuration, package.json, lock files, or global configuration. The repository can be installed as a Claude Code plugin or copied into Claude configuration directories manually. It includes a Node.js test suite and is distributed under the MIT license.
