Cursor: the AI-first editor
Cursor is a full code editor with AI built into every part of it: autocomplete, chat about your codebase, and agents that edit several files at once. You stay in control of each change and can review diffs before accepting them. It is the leading choice when you write code most of the day and want AI help without leaving your editor.
Choose Cursor if you want a familiar IDE workflow and fine-grained control over each edit.
Claude Code: the terminal agent
Claude Code runs in your terminal and works through larger tasks step by step: reading the codebase, planning, editing files, running commands and tests, and fixing what fails. It suits developers who are comfortable delegating a whole task, such as a refactor or a new feature, and reviewing the result.
Choose Claude Code if you do serious multi-step work and like the command line.
OpenAI Codex: start it and walk away
Codex focuses on tasks that run in the cloud while you do something else. You hand off a task, and it works in its own environment and comes back with changes to review. It is included with ChatGPT's paid plans, which makes it good value if you already pay for ChatGPT.
Choose Codex if you want to run several tasks in parallel, or you already have ChatGPT Plus.
Using them together
These tools overlap less than they seem. A common setup is Cursor as the daily editor, with a terminal or cloud agent for bigger tasks. Since each starts around $20 a month, try one editor and one agent before you commit to more.
Other options worth knowing
- GitHub Copilot has the lowest entry price, at $10 a month, and deep GitHub ties.
- Devin Desktop, the former Windsurf, is built for managing several agents.
- Google Antigravity and Kiro suit browser testing and spec-first teams.
