Claude Code, Codex CLI, Cursor, Cline, Roo Code, Open Claw, Hermes — they're all the same thing underneath.
They're agent frameworks: wrappers around a language model that add four things:
| Component | What it does |
|---|---|
| Model | The LLM that plans and reasons |
| Tools | File access, code execution, API calls |
| Memory | Context that persists across steps |
| Loop | Keeps running until the task is complete |
A regular chatbot answers and stops. An agent framework answers, acts, checks the result, and acts again.
| Framework | Made by | Interface | Best for |
|---|---|---|---|
| Claude Code | Anthropic | Terminal / VS Code | Agentic dev workflows, operator setup |
| Codex CLI | OpenAI | Terminal | GPT-4o based terminal agent |
| Cursor | Anysphere | VS Code fork | In-editor AI with autocomplete + chat |
| Cline / Roo Code | Community | VS Code extension | Open-source, model-agnostic agent |
| Open Claw | Community | Terminal | Lightweight terminal agent |
| Hermes | Community | Terminal | Custom agent scripting |
| Windsurf | Codeium | VS Code fork | Flow-based agentic coding |
| Aider | Paul Gauthier | Terminal | Git-native pair programmer |
Use Claude Code if: You want the most capable model (Claude Sonnet/Opus), operator-level customization (CLAUDE.md, skills, hooks, memory), and a terminal-first workflow.
Use Cursor if: You want a full IDE replacement with AI deeply integrated into the editing experience.
Use Cline/Roo Code if: You want a free, open-source, model-agnostic agent inside VS Code.
Use Codex CLI if: You're building on OpenAI's ecosystem and want a lightweight terminal agent.
The framework you pick matters less than how you configure it.
Claude Code with a good CLAUDE.md, a set of custom skills, and hooks set up correctly will outperform any out-of-the-box framework. Configuration > choice.
