Best AI Coding Tools in 2026: Cursor, Claude Code, Codex, GitHub Copilot, Devin and Cline Compared

For working in an editor, Cursor is the best pick; for big tasks in the terminal, Claude Code and Codex; and the cheapest start is GitHub Copilot with its free plan. I compare 8 tools using their pricing pages as of October 2026.

Piotr Olszewski · updated October 12, 2026

In 2026, choosing an AI coding tool comes down to two questions: do you want suggestions in your editor, or an agent that completes whole tasks on its own? For working in an editor, Cursor is the best. For agents that work across the whole repository, Claude Code and Codex, which come with a Claude or ChatGPT subscription. GitHub Copilot is the safest choice for companies already on GitHub, and Cline gives you full cost control thanks to your own API keys.

I checked pricing pages in October 2026. Prices are in US dollars, as listed by the vendors.

Quick picks

  • Best overall in the editor: Cursor - an editor with an agent, autocomplete and cloud agents.
  • Best terminal agent: Claude Code - included in every paid Claude plan, from $17 a month billed annually.
  • Best free: GitHub Copilot Free (2,000 completions and 50 chat requests a month) and Cline with your own API key.
  • Cheapest paid: GitHub Copilot Pro at $10 a month and ChatGPT Go at $8 a month with basic Codex access in the app.
  • Best for spec-driven work: Kiro - requirements and a plan before any code.

Cursor

Cursor logo
CursorAI coding agent and IDE that turns ideas into code, running tasks in parallel for developers and engineering teams.

Cursor is a VS Code-based editor with a built-in AI agent. You select code or describe a task, and the agent reads the project, changes several files at once, runs commands and shows you diffs to approve. It also has fast autocomplete, cloud agents and Bugbot for code review.

Who it's for: developers who want AI in their everyday editor workflow.

Price: per the pricing page, Hobby is free (limited agent requests, no card), the individual plan costs $20 a month, and Teams $40 per user per month. Higher individual tiers and annual billing are listed, but I haven't confirmed their amounts.

Downsides:

  • with heavy use of the strongest models, plan limits run out fast;
  • you have to move from your current editor (though VS Code settings import);
  • it's easy to accept large changes without reviewing them properly.

Claude Code

Claude logo
ClaudeAI assistant by Anthropic for chat, writing, coding and research, used by individuals and teams.

Claude Code is Anthropic's agent that runs in the terminal, in your IDE and in the browser. It takes a task, reads the repository, plans, edits files, and runs tests and commands. It shines on bigger jobs: refactoring, new features in a large project, fixing bugs from logs.

Who it's for: developers who work in the terminal, and teams automating repetitive work.

Price: per the pricing page, Claude Code is included in every paid Claude plan: Pro at $20 a month or $17 billed annually, Max from $100 a month (5x and 20x tiers), Team from $20 per seat billed annually. Limits are shared with chat, so coding and conversations draw from the same pool. You can also pay via the API.

Downsides:

  • on Pro, limits run out quickly during long sessions;
  • working in the terminal takes getting used to if you only know IDEs;
  • an agent with broad permissions can make lots of changes at once - work on branches.

Codex

OpenAI Codex logo
OpenAI CodexAI coding agent from OpenAI that handles engineering tasks like bug fixes, refactors, features and code reviews for developers and teams.

OpenAI's Codex is a coding agent available in ChatGPT, in the terminal (CLI), as an IDE extension and on iOS. It can work on a task in the cloud while you do something else, review code and integrate with Slack.

Who it's for: people already paying for ChatGPT, and teams that want to delegate tasks to the cloud.

Price: per OpenAI's pricing page, the Free plan lets you try Codex on short tasks, Go ($8 a month) gives limited access in the desktop app, Plus ($20 a month) gives full access on the web, CLI, IDE and iOS, and Pro from $100 a month gives higher limits. Business costs $20 per user per month billed annually ($25 monthly). You can also pay for Codex at API rates.

Downsides:

  • the most interesting cloud features start on Plus;
  • limits depend on the plan, and it's not always easy to predict when they'll run out;
  • like any agent, it needs its changes reviewed before merging.

GitHub Copilot

GitHub Copilot logo
GitHub CopilotAI coding assistant inside GitHub that helps developers write, review, and ship code faster.

GitHub Copilot is the most popular coding assistant: IDE suggestions, chat, agent mode, pull request reviews and an agent that works on GitHub issues. It runs in VS Code, JetBrains, Visual Studio, the terminal and the GitHub mobile app.

Who it's for: companies on GitHub, and developers who don't want to switch editors.

Price: per the pricing page, Free is $0 (2,000 completions and 50 chat requests a month). Pro costs $10 a month, Pro+ $39, Max $100. Each paid plan includes a monthly AI credit allowance ($15 on Pro, $70 on Pro+, $200 on Max; 1 credit = $0.01), and code completions are unlimited on paid plans. Business and Enterprise require contacting sales.

Downsides:

  • billing in AI credits is less transparent than the old request limits;
  • agent mode is less autonomous than tools like Claude Code or Cursor;
  • the Free plan has a low chat request limit.

Devin Desktop (formerly Windsurf)

Devin Desktop logo
Devin DesktopDesktop app to plan, run and review local and cloud coding agents from one editor-like workspace.

Windsurf has been renamed Devin Desktop. The vendor describes it as "a new name for Windsurf": the editor stays, but adds a hub for managing multiple agents (spaces, a Kanban view, agent coordination). Plans, settings and extensions carry over automatically with the update.

Who it's for: existing Windsurf users and people who want to run several agents at once.

Price: per the pricing page, Free is $0 (light agent limits, unlimited Tab completions and inline edits), Pro $20 a month, Max $200 a month, Teams $80 a month plus $40 per seat. The vendor says the SWE-2 Free model is free on Pro in Devin Desktop and the CLI until October 16, 2026.

Downsides:

  • the rename and product shift mean many docs and tutorials online still refer to Windsurf;
  • a big price jump between Pro and Max.

Devin

Devin is an autonomous agent from Cognition that you assign tasks to like a developer on your team: it gets access to the repository, works in the cloud and hands back a pull request. The same pricing covers Devin Desktop, so one plan gets you both the editor and the cloud agent.

Who it's for: teams that want to delegate well-defined, repetitive tasks.

Price: per the pricing page, the same as Devin Desktop: Free, Pro $20 a month, Max $200 a month, Teams $80 plus $40 per seat.

Downsides:

  • an autonomous agent needs a very precise task description;
  • the output still needs code review;
  • extra usage is billed at API rates.

Cline

Cline logo
ClineOpen-source AI coding agent for editors, terminal and SDK that plans and executes multi-file code changes with any model.

Cline is an open-source agent for VS Code and the terminal. You only pay for the models: plug in your own OpenAI, Anthropic, Google or other provider keys and you have full control over costs and model choice.

Who it's for: developers who want to choose the model and pay only for actual usage, and companies with their own API agreements.

Price: per the pricing page, Cline is free for individual developers. You pay for model inference based on usage, with no subscription. Enterprise is custom-priced.

Downsides:

  • API costs on large tasks can exceed a subscription;
  • you have to configure providers and keys yourself;
  • less polished than commercial editors.

Kiro

Kiro logo
KiroAI coding agent from AWS that turns prompts into specs, tests code correctness, and runs parallel agents for developers and teams.

Kiro from AWS focuses on spec-driven development: from a prompt it creates requirements and a plan, then the implementation, with an emphasis on tests and correctness in large projects.

Who it's for: teams that want more structure than "vibe coding", and AWS users.

Price: per the pricing page, Free gives you 50 credits, Pro costs $20 per user per month (1,000 credits), Pro+ $40 (2,000), Pro Max $100 (5,000), Power $200 (10,000). Extra credits cost $0.04 each.

Downsides:

  • the spec-first approach slows down small fixes;
  • 50 credits on the free plan is a short test.

How to choose

  • Editor or terminal? If you like IDEs - Cursor, Copilot, Devin Desktop. If you work in the terminal - Claude Code, Codex CLI.
  • Check what you already pay for. Have Claude Pro? Claude Code is included. Have ChatGPT Plus? Codex is included.
  • Compare limits, not just price. The $20 plans differ in how many hours of heavy agent work they can handle.
  • Company repository = business plan. Check that your code isn't used for training and that SSO is available.
  • Want cost control? Cline with your own API key, or pay via the API.
  • Test on a real task. Give two tools the same bug from your project and compare the results.

Common mistakes

  • Accepting changes without reading them. An agent can change 20 files at once. Review the diff and run the tests.
  • Working on the main branch. Put every agent task on its own branch and merge only after review.
  • Tasks that are too vague. "Fix the app" is a recipe for chaos. Specify the file, the expected outcome and how to verify it.
  • Secrets in the context. Don't paste API keys or passwords into the chat. Keep them in environment variables and exclude them from indexing.
  • Paying for three tools that do the same thing. One AI editor and one terminal agent is usually the maximum you need.
  • No tests. Without tests you don't know whether the agent fixed something or broke it.
