Claude Code, Cursor and Codex are AI coding agents that read your project, edit files and run commands. They differ in where you work. Claude Code is Anthropic's agent that started in the terminal, Cursor is a code editor built around agents with a choice of models, and Codex is OpenAI's agent inside ChatGPT. Pick by how you work.

Claude Code
What it is. Claude Code is Anthropic's agentic coding tool.
How you work with it. You describe what you want in plain language. It plans, writes code across files and asks permission before changing files or running commands. The same engine runs in the terminal, in VS Code and JetBrains extensions, in the Claude desktop app, in a browser at claude.ai/code and in the Claude apps for iOS and Android.
Strengths as documented. It is scriptable: you can pipe text into it and run it in CI with GitHub Actions or GitLab CI/CD. It supports MCP servers for outside tools, plus skills, hooks and subagents. You can run several agents in parallel, schedule recurring cloud tasks, and move a session between phone, browser and terminal. A managed GitHub Code Review service is listed for Team and Enterprise plans, and a local /code-review command works on any plan.
Things to know. It uses Claude models only. The model docs list Opus as the default on paid plans. The free Claude plan does not include it. As of November 10, 2026, the Claude pricing page lists Pro at $20 a month billed monthly, Max at $100 and Ultra at $200, all with Claude Code. You can also pay by API usage through an Anthropic Console account.
Cursor
What it is. Cursor describes itself as an AI editor and coding agent. The agent, your files and the diffs sit in one window.
How you work with it. You open your project, ask the agent to plan, build or fix something, then review the changes in place. Cursor Tab adds autocomplete as you type. A Cursor CLI covers the terminal, scripts and CI.
Strengths as documented. Model choice is the big one. Cursor's docs list models from Anthropic, OpenAI, Google and Meta next to Cursor's own Composer and Grok models. Cloud Agents run in isolated virtual machines, so they keep working when your laptop is closed. Bugbot reviews pull requests and comments on bugs and security issues. Rules, skills, subagents, hooks and MCP servers are supported.
Things to know. Plans changed this year. As of November 10, 2026, the Cursor pricing page lists a limited Free plan, Plus at $8 a month (Grok models only), Premium at $30, Super at $100 and Ultra at $200. Cloud Agents, Bugbot and third-party models start at Premium, and the page says third-party model usage is billed separately at API list price.
OpenAI Codex
What it is. Codex is OpenAI's coding agent. OpenAI now presents it as part of ChatGPT.
How you work with it. One ChatGPT account connects every surface: the ChatGPT desktop, web and mobile apps, the Codex CLI in your terminal, and an IDE extension for VS Code and compatible editors. Keep quick work local, or hand a longer task to Codex Cloud, where each task gets its own workspace.
Strengths as documented. If you already pay for ChatGPT, you may already have it. The docs cover parallel work through git worktrees and cloud environments, plus subagents, skills, MCP servers and scheduled tasks. Code review works locally with /review and on GitHub pull requests, either automatically or by commenting "@codex review".
Things to know. It uses OpenAI models. As of November 10, 2026, the Codex pricing page lists Plus at $20 a month with Codex on the web, in the CLI, in the IDE extension and on iOS, and Pro from $100 a month. Free and Go ($8) show lighter access in the desktop app, subject to rollout. An API key works in the CLI and IDE extension at API rates, without cloud features.
Claude Code vs Cursor
Claude Code is an agent you can run almost anywhere, with one model family. Cursor is an editor first, with many model families. To steer each edit inside an editor and try different models, use Cursor. To hand a task to an agent in a terminal, an app or a script and review the result, use Claude Code. They also work together: Anthropic's docs include a Claude Code extension install for Cursor, and Cursor lists Claude models in its model picker.
Codex vs Claude Code
These two are the closest match. Both have a CLI, IDE extensions, a desktop app, cloud tasks, mobile access, code review, MCP support and subagents. The practical differences are the models and the subscription you already hold. Codex comes with a ChatGPT plan and Claude Code comes with a paid Claude plan.
Cursor vs Codex
Cursor gives you a full editor and a choice of models from several companies, including OpenAI's. Codex gives you OpenAI's agent across the ChatGPT apps, a CLI and the cloud. Choose Cursor if you want to live in the editor. Choose Codex if you want coding next to the rest of your ChatGPT work. They are not exclusive: OpenAI's docs list Cursor among the editors the Codex extension supports.
Which should you start with?
- Pick Claude Code if you are comfortable giving instructions in a terminal or a chat window, want to automate chores with scripts or CI, or already pay for Claude.
- Pick Cursor if you want to see your files, the agent and the diff side by side, like autocomplete while you type, or want to switch between models from different companies.
- Pick Codex if you already use ChatGPT every day, want to start tasks from the ChatGPT app or your phone, or want cloud tasks tied to your GitHub repos.
- Run the same small task in each. Many builders end up using two of these. Take one real task (a bug, a small feature, a test file) and try it in each tool. An hour of that tells you more than any comparison page.
To see how other Charlotte builders work with these tools, come to a meetup. Dates are on our events page, or join the mailing list.
Other AI coding agents worth knowing
- GitHub Copilot: GitHub's coding agent, which can take work from an issue or pull request and run tasks in parallel.
- Jules: Google's autonomous coding agent for tasks like bug fixes, version bumps and tests.
- Devin Desktop: the new name for Windsurf, from Cognition. A hub for running agents on your machine or in the cloud.
- Amp: a coding agent that runs in cloud sandboxes and on your own machine through a CLI.
- OpenCode: an MIT-licensed open source coding agent that works with many model providers, including local models.
What builders at our meetups have said they use
Not a poll. Only what our recaps report from two pitches.
- At the October 21 meetup, Bart Baldwin said Stubbly began with the Replit agent, with Grok helping on planning.
- At the November 4 meetup, the Gridramp team said they build features with coding agents in Cursor, and use Claude to question each feature idea before they build it.

FAQ
Is Claude Code better than Cursor?
Neither is better for everyone. Claude Code is an agent you run from a terminal, app or browser using Claude models, and Cursor is an editor with agents and a choice of models. Try both on the same small task.
Can a non-developer use these tools?
Yes, with patience. Claude Code runs in a browser with no local setup and its docs include a guide for people who have never opened a terminal. Codex runs inside the ChatGPT apps. You still need to read what the agent did and test the result.
Do I need to pay for all three?
No. Start with one. If you already pay for ChatGPT Plus or Claude Pro, the pricing pages show Codex or Claude Code is included as of November 10, 2026. Cursor has a limited free plan you can use to look around.
Can I use Claude models inside Cursor?
Yes. Cursor's docs list Anthropic's Claude models. Cursor's pricing page says third-party models are available from the Premium plan up and are billed separately at API list price, and that the Plus plan is limited to Grok models.
What is the difference between Codex and ChatGPT?
Codex is OpenAI's coding agent, and OpenAI now offers it inside ChatGPT. One ChatGPT account signs you in to the apps, the CLI, the IDE extension and Codex Cloud.
