The best AI coding assistants in 2026

The short answer: for most developers our pick in 2026 is still GitHub Copilot as the default: GitHub lists a free plan and a Pro plan at $10 a month, and Copilot runs in VS Code, Visual Studio, JetBrains IDEs, Xcode, Eclipse, Neovim, Zed and the terminal. For hard, multi-file work you hand off whole, pick a coding agent: Claude Code, included in the Claude Pro plan that Anthropic lists at $20 a month, or OpenAI Codex, included in the ChatGPT Plus plan that OpenAI lists at $20 a month. For an agent inside the editor, Cursor is the pick, but its plans changed in October 2026 (see below). On a tight budget, free ways in include Copilot Free, Cursor Free, ChatGPT Free (OpenAI says Codex is included), Junie Lite, Google Antigravity's free Individuals plan and Cline (free; you pay your model provider), and Cursor lists its Plus plan at $8 a month for Cursor's own Composer and Grok models only. To filter every plan by price and features yourself, use our AI coding assistant comparison tool.

The category now has two halves. In-editor assistants (autocomplete, inline chat, a sidebar agent) help while you type in VS Code or JetBrains. Coding agents (Claude Code, OpenAI's Codex, JetBrains' Junie, Google's Antigravity CLI) take a whole task: they read the repo, edit across files, run commands and tests, and hand back a diff or a pull request. Most of the tools below now do both, so the useful question is what you are buying it for.

Which AI coding assistant should you pick?#

• Best default for most developers: GitHub Copilot
• Best for hard, autonomous coding work: Claude Code
• Best agent if you already pay for ChatGPT: OpenAI Codex
• Best AI code editor with a built-in agent: Cursor
• Best for JetBrains users: JetBrains AI (Junie)
• Best open-source, bring-your-own-model agent: Cline
• Best for Google Cloud teams: Gemini Code Assist
• For AWS shops: Amazon Q Developer, though AWS now points Q Developer IDE plugin users to Kiro (see "Also worth a look")

Every price below is the vendor's own listed price in US dollars, read on each vendor's page on October 23, 2026. Plans and model names change often, so check the vendor's page before you buy.

GitHub Copilot: Best default for most developers#

GitHub Copilot is GitHub's coding assistant. GitHub says it runs in VS Code, Visual Studio, JetBrains IDEs, Xcode, Vim, Neovim, Zed and Eclipse, in the terminal through Copilot CLI, in a desktop app, on the web and on mobile. It is multi-model: GitHub's plans page lists models from Anthropic (including Claude Opus 5.5 and Fable 5.1), OpenAI (including GPT-6.1 Sol), Google (Gemini 4 Argon), xAI (Grok 4.7) and others.

The big change this year was billing. On April 27, 2026, GitHub announced that every Copilot plan would move to usage-based billing on June 1, 2026. Each plan now includes a monthly allowance of GitHub AI Credits, and GitHub says credits draw down at one US cent each. GitHub also says code completions and next edit suggestions do not use credits and are unlimited on every paid plan.

GitHub lists Pro at $10 a month with 1,500 AI credits, and Pro+ at $39 with 7,000 credits and access to premium models. Max, which GitHub lists at $100 a month, includes 20,000 credits and priority access to premium models. The free plan includes 2,000 completions a month, limited chat and agent use, and automatic model selection only. For organizations, GitHub lists Business at $19 per granted seat a month (1,900 credits a user) and Enterprise at $39 (3,900 credits a user).

Who it's for: Any developer who wants one tool that works everywhere without configuration debt, and a free way to try agentic coding: GitHub includes agent mode on its free plan. It rewards you most if you already live on GitHub.

When to pick something else: If large, autonomous refactors are your daily work, a dedicated agent (Claude Code, Codex, or Cursor's agent) is built for that job.

---

Claude Code: Best for hard, autonomous coding work#

Claude Code is Anthropic's agentic coding tool. Anthropic's documentation says it reads your codebase, edits files, runs commands and works with your development tools, and that it runs in the terminal, in VS Code and JetBrains extensions, in a desktop app and in the browser. You point it at a repo and give it a task; it plans, edits across files, runs commands and tests, and iterates. On Pro, Max, Team, Enterprise and Anthropic API accounts its default model is Claude Opus 5.5, according to Anthropic's model-configuration docs, and in Claude Code that model has a native 1-million-token context window.

Who it's for: Developers doing genuinely hard, multi-file, autonomous work (big refactors, debugging across a large codebase, new features end to end) who are willing to pay for it.

Access & cost: Claude Code is included in every paid Claude plan. Anthropic lists Pro at $20 a month, or $17 a month billed annually. Anthropic lists Max 5x at $100 a month and Max 20x at $200 a month. Team Standard seats, which Anthropic lists at $25 a month billed monthly, include it too. You can also pay per token through the Anthropic API: Anthropic lists Opus 5.5 at $4 per million input tokens and $20 per million output tokens. Anthropic says usage limits apply on every plan, which is why heavy daily users end up on Max.

When to pick something else: If you mostly want smart autocomplete and inline chat, this is more than you need: Copilot or Cursor fit better.

---

OpenAI Codex: Best agent if you already pay for ChatGPT#

Codex is OpenAI's coding agent. OpenAI's docs list it in the ChatGPT desktop app, on the web, in the CLI, in an IDE extension and on iOS, and the Codex CLI is open source under the Apache-2.0 license on GitHub. You delegate a task, it works through it and hands back the change, and cloud tasks run on OpenAI's machines while you do something else. For complex coding and agentic work OpenAI recommends GPT-6.1 Sol. GPT-5.5 retired from Codex for ChatGPT sign-ins on October 14, 2026.

Who it's for: People already paying for ChatGPT who want a capable agent without adding another vendor, and anyone who likes kicking off cloud tasks that run in the background.

Access & cost: Codex comes with ChatGPT plans. OpenAI lists Go at $8 a month, Plus at $20 a month, and Business at $25 per user a month billed monthly, or $20 billed annually for two or more users. OpenAI lists Pro at $100, $200 or $500 a month. You can also run the CLI, SDK or IDE extension with an API key and pay API rates, without the cloud features.

When to pick something else: If you also want strong inline autocomplete in your editor, pair Codex with Copilot or Cursor rather than leaning on it alone.

Cursor: Best AI code editor with a built-in agent#

Cursor is an AI code editor based on the VS Code codebase, which keeps the editor familiar if you come from VS Code. Cursor's docs say its Agent can complete complex coding tasks on its own, run terminal commands and edit code, and paid plans from Premium up add cloud agents. Cursor's docs say it supports frontier models from OpenAI, Anthropic, Google, SpaceXSI and more, alongside Cursor's own Composer 2.5.

Pricing changed in October 2026. Cursor is now sold as part of The X Subscription, which Cursor's docs describe as one subscription for Grok, Cursor and X. Paid plans include one weekly usage pool shared across Cursor and Grok, and it covers what Cursor calls its own models: Composer 2.5 and Grok 4.7, 4.6 and 4.5. Claude, GPT and Gemini are not in the pool: from Premium up you pay for them at API list price from prepaid credit, and on Plus they are not available. Cursor lists Plus at $8 a month (Cursor's own Composer and Grok models only), Premium at $30 a month and Teams from $30 per user a month. Cursor lists Super at $100 a month and Ultra at $200 a month, and the free plan is limited. Cursor's docs say the legacy Hobby, Start, Pro, Pro+, Ultra and Teams Standard and Premium plans continue for existing customers.

Who it's for: Engineers who want an in-editor agent doing real chunks of work on a familiar VS Code surface, and who are happy with Composer and Grok or willing to pay API rates for other models.

When to pick something else: If Claude or GPT is the model you actually want, price it first, because on the new plans those run at API rates on top of the subscription. The New Stack also reported that OpenAI announced in August 2026 plans to withdraw direct access to its models through Cursor; Cursor's docs still listed GPT models on October 23. Pick something else too if you are locked into JetBrains.

JetBrains AI (Junie): Best for JetBrains users#

JetBrains AI is the AI layer across the JetBrains IDEs (IntelliJ IDEA, PyCharm, GoLand, WebStorm and the rest), and Junie is JetBrains' coding agent. JetBrains says Junie works with any model you choose, with more than 10 supported through bring-your-own-key (Claude Opus 5.5, GPT-6.1 Sol, Gemini 3.1 Pro and Grok 4.7 among them), and that it runs in the terminal as a CLI, inside the IDEs, as a GitHub Action and in GitLab CI/CD. On top of that sits JetBrains Air, which JetBrains describes as one system for building software with agents: it works with Claude Agent, Codex, Junie, Copilot, OpenCode and any agent you connect over ACP.

Pricing: JetBrains lists Junie Lite, a free model in every JetBrains account, and bring-your-own-key use at your provider's rates with zero markup. With annual billing and individual pricing selected on its Junie page, JetBrains lists AI Pro at $8.33 per user a month (10 AI credits per 30 days) and AI Ultimate at $25.00 per user a month (35 AI credits per 30 days).

Who it's for: Teams already invested in JetBrains IDEs who want an agent that uses the IDE's own code intelligence, and now a CLI agent to match.

When to pick something else: You use VS Code or another non-JetBrains editor: the integration advantage disappears.

---

Cline: Best open-source, bring-your-own-model agent#

Cline is an open-source coding agent under the Apache-2.0 license. It runs as a VS Code extension, a CLI, a desktop app and an SDK, and Cline's pricing page lists a JetBrains extension on its Enterprise plan. Its VS Code Marketplace listing showed more than 5.7 million installs on October 23, 2026. It is a real agent, not just chat: in Plan mode it agrees a strategy with you, then in Act mode it edits files and runs commands, with your approval at each step unless you switch on auto-approve. It supports MCP servers for outside tools and data, and it works with any model: Claude, GPT, Gemini, local models through Ollama or LM Studio, or any OpenAI-compatible endpoint, with your own key.

Cost: Cline says the open-source extension is free for individual developers. You pay only for AI inference, through your own API keys or the Cline provider. Enterprise is priced on request.

Who it's for: Developers who want an open-source, auditable agent inside plain VS Code, running on their own model keys, and teams that want agent capability without committing to a forked editor or a single vendor.

When to pick something else: If you want a plug-and-play tool with support, a paid tool (Copilot, Cursor, Claude Code) gets you productive faster.

---

Gemini Code Assist: Best for Google Cloud teams#

Gemini Code Assist is Google's coding assistant for businesses, sold in Standard and Enterprise editions as part of Gemini for Google Cloud. It works in VS Code, JetBrains IDEs, Cloud Workstations and Cloud Shell Editor, has an agent mode (still in preview, with MCP support), and includes Gemini CLI, Google's open-source terminal agent. Google says Gemini 3 is available to Standard and Enterprise subscribers on the Preview release channel. Enterprise adds code customization, Gemini in Apigee and Application Integration, and higher daily agent limits.

The change for individuals: Google says that on June 18, 2026, Gemini CLI and the Gemini Code Assist IDE extensions were replaced by Antigravity CLI and Antigravity for unpaid users and Google One subscribers. So the free way into Google's coding tools is now Google Antigravity, an agent-first app, IDE and CLI whose Individuals plan Google lists as free, with Google AI Pro and Ultra raising the limits.

Pricing: Google lists Code Assist licences by the hour. At 730 hours a month (our arithmetic), Google's listed rates come to $22.80 per user a month for Standard on a monthly commitment, or $19 on a 12-month commitment, and $54 or $45 for Enterprise.

Who it's for: Teams building on Google Cloud who want an assistant inside their Google Cloud tools and billing.

When to pick something else: You are not on Google Cloud: there is no strong reason to choose it over Copilot.

---

Also worth a look#

• Google Antigravity: Google's agent-first IDE, app and CLI. Google lists the Individuals plan as free, with unlimited tab completions and command requests and basic weekly rate limits, and Gemini 4 Argon is available in it for Google AI Pro and Ultra subscribers. For individuals it is now Google's main coding tool (see Gemini Code Assist above).
• Devin Desktop (formerly Windsurf): Cognition says Devin Desktop is the new name for Windsurf, and windsurf.com now opens the Devin Desktop page. Treat it as part of Cognition's Devin line rather than a standalone Cursor alternative.
• Amazon Q Developer and Kiro: AWS lists Q Developer Free with 50 agentic requests a month and Q Developer Pro at $19 per user a month. But AWS's Q Developer page now carries an end-of-support notice for the IDE plugins and points users to Kiro for agentic coding, chat and MCP support, so an AWS shop starting today should look at Kiro first.
• Continue: the open-source VS Code and JetBrains extension. Its site now says Continue was acquired by Cursor, and its open-source code remains available on GitHub under Apache-2.0.

What changed in AI coding assistants in 2026#

The updates that matter for a buyer this year, oldest first:

• April 27, 2026: GitHub announced that every Copilot plan would move to usage-based billing on June 1, 2026, with a monthly allowance of AI credits on each plan. Completions and next edit suggestions stayed outside the meter.
• June 18, 2026: Google replaced Gemini CLI and the Gemini Code Assist IDE extensions with Antigravity CLI and Antigravity for unpaid users and Google One subscribers. Gemini Code Assist itself is now a business product.
• October 2026: Cursor moved new customers to The X Subscription, which bundles Cursor with Grok and X, and started billing Claude, GPT and Gemini at API rates (Cursor's docs; The New Stack covered the announcement on October 13).
• October 14, 2026: GPT-5.5 retired from Codex for ChatGPT sign-ins, and OpenAI now recommends GPT-6.1 Sol for complex coding.
• Also true on October 23, 2026 (the vendors' pages give no date): Claude Code's default model on paid plans is Claude Opus 5.5 (Anthropic's docs), Windsurf is now Devin Desktop (Cognition), Continue was acquired by Cursor (Continue), JetBrains offers Air to run several agents in its tools, and AWS put an end-of-support notice on the Amazon Q Developer IDE plugins and pointed users to Kiro.

The common thread is the coding agent. Claude Code, OpenAI's Codex CLI, JetBrains' Junie CLI, Copilot CLI and Google's Antigravity CLI all live in your shell, not only your editor, and they change the unit of work: instead of accepting a suggestion line by line, you describe a task and the agent does it end to end, then shows you a diff or a pull request. If your idea of "AI coding" is still gray ghost-text in VS Code, that is the part to try.

How to choose an AI coding assistant#

1. Start with your editor, but do not stop there. An assistant you fight to install is one you stop using, so match the tool to where you already work: JetBrains AI in JetBrains, Copilot or Cursor in VS Code. But the coding agents (Claude Code, Codex, Junie CLI) work outside any one editor, so do not assume the right tool has to live inside your IDE.

2. Decide how autonomous you actually want it. Autocomplete and chat are table stakes now. The real 2026 difference is agentic capability: can it plan, edit, run tests and iterate without babysitting? If that is central to your work, look first at Claude Code and OpenAI Codex (coding agents) and Cursor (in-editor). If you mostly want smart autocomplete and inline chat, Copilot is enough: GitHub lists Pro at $10 a month, against the $20 that Anthropic and OpenAI list for Claude Pro and ChatGPT Plus.

3. Budget for usage, not just the sticker price. Copilot draws down AI credits, Cursor has a weekly pool plus API-rate billing for other models, JetBrains AI runs on credits, and Claude and ChatGPT plans have usage limits. The listed monthly price is the floor, not the ceiling: heavy agent use can multiply it. Pick a plan with headroom, or watch the first month closely.

4. Know where your code is going. Every cloud tool sends your code to a third-party server. For most teams that is fine. For regulated industries or genuinely sensitive code it is a compliance question, and an open-source, bring-your-own-key agent like Cline pointed at a local model is the answer that keeps code on your machine.

5. Do not pay for an ecosystem you are not in. Gemini Code Assist's Google Cloud depth means nothing on AWS, where AWS now points to Kiro. JetBrains AI's IDE integration means nothing in VS Code. Match the tool to the stack you actually run.

---

The bottom line#

For most developers in 2026, GitHub Copilot is still the right default: broad editor support, a free plan and a Pro plan at GitHub's listed $10, and a real agent mode make it a low-risk way into the whole category. But the ceiling has moved. For hard, autonomous work, Claude Code and OpenAI Codex are the tools to try, and if you want that agent inside your editor, Cursor is the one to try, after pricing the models you want on its new plans. Try a coding agent on a real task for a week before you decide Copilot is enough.

Our picks#

🏆 Top pick: GitHub Copilot (best default). Broad editor support, a free plan and a Pro plan at GitHub's listed $10 make it a low-cost, low-risk way for most developers to start, with a real agent mode when you're ready for it.
