Best AI coding agents compared (2026): Claude Code, Codex, Cursor and more
Six AI coding agents compared for people who build by prompting: where each runs, what it does well, what to watch and its current price from its own pricing page.
Key Takeaways
- Claude Code is our top pick for most people building whole apps. It runs in the terminal, VS Code, JetBrains, a desktop app and the web, and is included from Claude Pro at $20 a month.
- Codex is the natural choice if you already pay for ChatGPT. It’s included from ChatGPT Free upward, with a CLI, IDE extension, desktop app and Codex Cloud.
- Cursor suits people who want an editor in front of the agent. Its plans are now built around Grok models, with third-party models billed at API list price on paid tiers.
- GitHub Copilot fits teams already living in GitHub. Assign an issue to Copilot and it opens a pull request; Pro is $10 a month.
- Check how each plan meters usage. Five-hour windows, weekly pools, credits and API-rate billing all behave differently on a heavy week.

A coding agent is an AI that works on a codebase the way a developer does: it reads files, plans, edits many files, runs commands and tests, and reports back. In November 2026 the main options differ less in raw model quality than in where they run, how they fit your workflow, and how their plans meter usage. This comparison covers six agents that people building with AI actually choose between: Claude Code, Codex, Cursor, GitHub Copilot, Devin and Google Antigravity. Every description and price comes from the vendor’s own documentation or pricing page as of 11 November 2026. These are agents that write code; none of them is a hosting platform, so we close with a note on where the apps they build can run.
What makes a good coding agent for vibe coders
Developers and vibe coders want slightly different things from an agent. Developers prize editor integration and fine control. People building mainly by prompting need four things more: the agent should finish tasks without hand-holding, check its own work, explain what it changed, and be predictable on cost.
So we compared each agent on where it runs, how it verifies work, how it takes standing instructions, how it connects to outside tools (MCP support matters here), and how its plan meters usage. We didn’t run benchmarks; model rankings shift monthly and every agent here offers strong models.
1. Claude Code
Best for: delegating whole features, with the agent running tests and fixing failures before it reports back.
Anthropic describes Claude Code as “an agentic coding tool that reads your codebase, edits files, runs commands, and integrates with your development tools.”
What it does well
It runs nearly everywhere: a terminal CLI, extensions for VS Code (and Cursor) and JetBrains, a desktop app that shows diffs visually and runs sessions side by side, and the web at claude.ai/code for long tasks that keep going after you close the laptop. It reads a CLAUDE.md file each session (or an existing AGENTS.md), works directly with Git including commits and pull requests, connects to tools over MCP, and supports hooks, skills, subagents and scheduled tasks.
For non-engineers, built-in review helps: /code-review checks your branch’s changes for correctness bugs in a separate subagent.
What to watch
Subscription usage resets on five-hour and weekly windows. Heavy users often move from Pro to Max. The desktop app requires a paid subscription.
Price
Included with Claude Pro ($20 a month, or $17 a month billed annually), Max ($100 a month, 5x Pro usage), Ultra ($200 a month), Team and Enterprise. Not included on Free. It also runs on an Anthropic Console account billed per token.
Get started
On macOS, Linux or WSL: curl -fsSL https://claude.ai/install.sh | bash, then cd into your project and run claude. Windows and Homebrew options are in Anthropic’s docs.
2. Codex
Best for: anyone already paying for ChatGPT who wants a capable agent with no extra subscription.
OpenAI lists Codex surfaces as the Codex CLI, the Codex IDE extension, the ChatGPT desktop, mobile and web apps, and Codex Cloud.
What it does well
Availability: it’s included in ChatGPT Free, Go, Plus, Pro, Business, Edu and Enterprise. It reads AGENTS.md files, combining them from the repository root down to your working folder, which makes project instructions easy to share across tools. On Pro plans, OpenAI says there’s currently no five-hour limit.
What to watch
On Plus and standard Business, OpenAI publishes estimated local messages per five-hour window that vary widely by model, and notes they “are not fixed message limits.” Free and Go are described for quick and lightweight coding tasks.
Price
Free; Go $8 a month; Plus $20 a month; Pro from $100 a month (with $100, $200 and $500 options); Business $25 per user monthly or $20 billed annually; Enterprise and Edu by quote. It can also use an API key, billed at standard API rates.
Get started
OpenAI’s CLI page gives curl -fsSL https://chatgpt.com/codex/install.sh | sh for macOS and Linux. Run codex in a project folder and choose Sign in with ChatGPT.
3. Cursor
Best for: semi-technical builders who want to watch the code change in an editor and steer as they go.
Cursor is an AI code editor with an agent, chat, tab completion and, on higher tiers, cloud agents and automations. Its current pricing page describes plans built around Grok models, with a usage pool shared across Cursor and Grok.
What it does well
The editor experience: inline diffs, quick edits and a familiar VS Code-style interface. Project rules live in .cursor/rules as .mdc files, and Cursor reads AGENTS.md in the project root and subfolders. It supports MCP. Premium and above add cloud agents, automations, code hosting and AI code reviews.
What to watch
Model access depends on the plan. Plus covers Grok models only. On Premium, Super and Ultra, third-party models such as Claude and GPT are available at API list price, billed by usage, so if you prefer those models, budget for usage on top of the plan. Allowances refresh weekly.
Price
Free; Plus $8 a month; Premium $30 a month (about 4x Plus usage); Super $100 a month (about 15x); Ultra $200 a month (about 50x); Teams from $30 per user a month; Enterprise custom.
4. GitHub Copilot
Best for: people and teams whose work already lives in GitHub issues and pull requests.
Copilot includes chat and agent features in editors and a coding agent on GitHub. GitHub’s plans page describes the coding agent simply: “Assign work to Copilot and it creates a pull request.”
What it does well
Fitting into an existing GitHub workflow. You write an issue, assign it, and review a pull request, which builds in a review step by design. The work happens in the background while you do something else. On Pro+ and Max, Copilot can also delegate tasks to third-party agents, including Claude and Codex (in preview).
What to watch
Plans are measured in GitHub AI Credits, where one credit is $0.01, with a base allotment plus a flex allotment each month. The Free plan doesn’t include the coding agent. You still need somewhere to host the app.
Price
Free; Pro $10 per user a month ($15 of monthly credits in total); Pro+ $39 ($70 of credits); Max $100 ($200 of credits).
5. Devin (Devin Desktop, formerly Windsurf)
Best for: people who want to run and manage several agents from one place, locally and in the cloud.
Cognition’s FAQ says “Devin Desktop is the new name for Windsurf,” as of 2 June 2026: the same editor and features, with an Agent Command Center for managing multiple agents now front and centre. The Devin brand also covers Devin Cloud, Devin CLI and Devin Review.
What it does well
Multi-agent management in an IDE, plus cloud agents on paid plans. The Pro plan lists frontier models from several providers as well as open-source models, and free use of Cognition’s SWE-2 model.
What to watch
Extra usage beyond plan quotas is billed at API pricing. If your organization manages software by name, Cognition’s FAQ notes the rename changed the app’s name, which can affect allowlists.
Price
Free with a light agent quota; Pro $20 a month; Max $200 a month; Teams $80 a month plus $40 per full developer seat; Enterprise by quote.
6. Google Antigravity
Best for: Gemini users and people who want a capable agent on a free individual tier.
Google Antigravity is Google’s agent platform; its pricing page lists two products, the Antigravity App and the Antigravity CLI. If you used Gemini CLI on a personal account, this is where that access now lives.
What it does well
A $0 Individuals plan that includes access to a variety of agent models, unlimited tab completions and command requests, with basic weekly rate limits. Google AI Pro and Ultra subscribers get higher limits and a flexible AI credit pool.
What to watch
The pricing page describes limits qualitatively rather than in numbers, so test it on a real project before relying on it for daily work. Prices for Google AI Pro and Ultra are set on Google’s subscription pages rather than the Antigravity page.
Price
Individuals $0; Google AI Pro and Ultra via Google’s subscriptions; Business through Google Cloud from $30 per seat a month, or pay-as-you-go with no seat fee.

How to choose
Start from what you already pay for and where you like to work.
If you already subscribe to Claude or ChatGPT
Try the agent you already have first: Claude Code on Claude Pro, or Codex on any ChatGPT plan. Both are capable enough that the deciding factor is usually comfort with the interface.
If you want to see the code
Cursor or Devin Desktop put the agent inside an editor. Claude Code’s VS Code extension and desktop app are another route.
If your work is organized in GitHub
Copilot’s issue-to-pull-request flow matches that well, and Pro+ can delegate to Claude and Codex agents.
If cost is the main constraint
Codex on ChatGPT Free and Antigravity’s Individuals plan have no subscription cost. Expect tighter limits.
Common mistakes when picking an agent
These matter more than which agent wins a benchmark this month.
- Choosing by benchmark headlines instead of trying your own project for a few evenings.
- Ignoring how usage is metered, then stalling mid-week when the allowance runs out.
- Paying for several overlapping subscriptions. Most people need one main agent.
- Skipping instruction files. A short AGENTS.md or CLAUDE.md improves every agent.
- Forgetting that none of these host your app. Plan where it will run before you build.
- Giving an agent broad permissions on a machine that holds production credentials in plain files.
A note on where the app runs
Every agent above writes and changes code; none of them is a hosting platform. You still need a database, sign-in and hosting, either services you set up yourself or a platform the agent can drive over MCP. Floot is one such platform: Claude Code, Codex and Cursor can connect to it through its MCP server and create the app’s Postgres database, logins and hosting in the same session.

Frequently Asked Questions
What is the best AI coding agent in 2026?
For most people building whole apps by prompting, Claude Code is our top pick. Codex is the best value if you already pay for ChatGPT, Cursor suits people who want an editor, and Copilot fits GitHub-centred teams.
Claude Code vs Codex: which is better?
Both are capable agents with terminal, editor and cloud options. Claude Code is included from Claude Pro at $20 a month; Codex is included from ChatGPT Free. Pick the one tied to the subscription you already use, then try the other on the same task.
Is there a free AI coding agent?
Codex is included in ChatGPT Free, Google Antigravity has a $0 Individuals plan, and Cursor, Copilot and Devin have free tiers with limited agent use. Claude Code isn’t included in Claude’s Free plan.
What happened to Windsurf?
Cognition renamed it Devin Desktop on 2 June 2026. Its FAQ says it’s the same IDE and features, with the Agent Command Center now the main view.
Can I use more than one agent on the same project?
Yes. Keep shared instructions in AGENTS.md, which Codex and Cursor read and Claude Code can read, and work on separate Git branches so agents don’t overwrite each other.
Do coding agents deploy my app?
They can run deploy commands for a host you’ve set up, and some can drive hosting platforms through MCP. None of them provides hosting itself.
