The best AI coding tools in September 2026: Cursor, Claude Code, GitHub Copilot, Codex, Devin Desktop, Gemini CLI, Lovable and more, with checked prices.
AI coding tools split into three kinds in 2026, and most comparisons blur them together. AI editors put models inside the place you write code, with autocomplete, inline edits and an agent in a side panel. Coding agents take a whole task, from a bug report to a feature, and work through it in your terminal or in the cloud while you do something else. App builders skip the editor entirely and turn a description into a running app. Each kind has a different best tool, and the price models differ too: plans now come with credits, token allowances or usage multiples rather than simple unlimited use.
How we built this list: every pricing page was checked on September 29, 2026, and each tool was assessed from its documentation, plans and our individual reviews. AIVario's own code is maintained with Claude Code, as described in our Claude review; the other tools here are researched rather than tested side by side.

Cursor is a fork of VS Code rebuilt around AI, and it remains the editor its rivals measure themselves against. The agent plans and edits across a project, cloud agents run tasks in the background, Composer is Cursor's own fast coding model, and MCP servers, skills and hooks connect it to other tools. Because it is a VS Code fork, extensions, themes and keybindings carry over. Cursor now belongs to SpaceX, which completed a $60 billion purchase of its maker, Anysphere, in August 2026 and placed it alongside Grok in its SpaceXAI division.
Hobby is free with limited agent requests. Pro costs $20 a month, or $16 billed yearly, Pro+ $60 for three times Pro's agent limits and Ultra $200 for twenty times. Teams costs $40 per user ($32 yearly) and adds shared rules, Bugbot code reviews, analytics and SSO. The trade-off is lock-in to one editor: developers who live in IntelliJ or Xcode cannot bring Cursor with them. Our Cursor vs GitHub Copilot comparison covers the choice in detail.
GitHub Copilot is the value pick and the most portable. It installs into VS Code, Visual Studio, JetBrains IDEs, Xcode, Neovim, Eclipse and Zed, and adds agent mode in the IDE, a cloud agent that turns GitHub issues into pull requests, code review and a CLI.
The free plan includes 2,000 completions a month and limited chat and agent use with models such as Claude Haiku 4.5 and GPT-5 mini. Pro at $10 a month makes completions unlimited and includes $15 of GitHub AI Credits for chat, agents and reviews, plus access to Claude Code and OpenAI's Codex as third-party agents inside Copilot. Pro+ at $39 adds premium models including Claude Opus, and Max at $100 carries $200 of credits. Business costs $19 per user with pooled credits and IP indemnity.
The editor once called Windsurf now belongs to Cognition, maker of the Devin agent, and was renamed Devin Desktop on June 2, 2026. It is an agent-first VS Code fork, with unlimited Tab completions and inline edits even on the free plan, and Pro connects it to Devin Cloud for background agents.
Pro costs $20 a month with frontier models from OpenAI, Anthropic, Google and SpaceXAI, and Cognition's own SWE-2 model is free in Devin Desktop and its CLI through October 16, 2026. Max costs $200, and Teams $80 a month plus $40 per full seat. Quotas refresh daily and weekly, and extra usage is billed at API prices.
Kiro, from Amazon Web Services, pushes a spec-first workflow: it turns a request into requirements, a design and a task list before writing code, which suits teams that want reviewable plans. Its credits are simple to read. Free includes 50, Pro $20 a month for 1,000, Pro+ $40 for 2,000 and Pro Max $100 for 5,000, with add-on credits at 4 cents each and a $200 tier for 10,000.
Developers committed to IntelliJ, PyCharm or Rider get AI natively through JetBrains AI Assistant. AI Free includes 3 AI credits per 30 days, AI Pro costs €100 per user a year for 10 credits, and AI Ultimate €300 for 35, with AI Pro included in the All Products Pack. Zed, the fast Rust-built editor, has its own AI features and a Pro plan for people who want speed over an ecosystem.
Claude Code is Anthropic's coding agent for the terminal and IDEs, and the tool most associated with delegating real work to AI. Give it a task and it reads the repository, plans the change, edits across files, runs the tests and fixes its own failures, asking before risky operations.
It is included in Claude Pro at $20 a month, or $17 billed yearly, with more room on Max at $100 for five times Pro's usage or $200 for twenty times. Anthropic publishes limits only in relative terms, and heavy daily users often hit Pro's ceiling mid-task, which is what pushes them to Max. Through the API, Sonnet 5 costs $2 per million input tokens and $10 per million output, and Opus 5.5 $4 and $20. See Claude Code vs Cursor for how the two fit together.
OpenAI's Codex comes with every ChatGPT plan, runs locally in the terminal and IDE or in the cloud, and reviews pull requests on GitHub. It shares its allowance with ChatGPT Work, and OpenAI is unusually specific about limits: on Plus it estimates 15 to 150 local messages per five hours with GPT-6 Sol, and on the $100 Pro tier 70 to 700. Plus costs $20, Pro starts at $100, and Codex can also run on an API key at API prices, which suits automation in CI.
Google offers the strongest free option. Gemini CLI is an open-source terminal agent, and Gemini Code Assist is free for individual developers with high limits and a 1 million token context window. Gemini subscribers on Google AI Pro at $19.99 a month get higher limits across both, plus base limits in Antigravity, Google's agentic development platform. Companies pay $19 or $45 per user a month for Code Assist Standard or Enterprise on annual terms.
Cline and Aider are open-source agents that run with the model of your choice through your own API key. Cline works inside VS Code and asks for approval before each file change or command; Aider works in the terminal and commits its changes to git as it goes. Both are free, and your costs are whatever the model provider charges, which can be very low with cheaper models such as DeepSeek or high with frontier ones.
Devin itself is the most autonomous option: assign a task in plain language and it plans, codes, tests and opens a pull request from its own cloud environment. Cognition cut its entry price from $500 to $20 a month in 2025, and it now comes with the Devin Desktop plans. It works best on well-scoped tasks; ambiguous ones burn usage without a good result.
Lovable is the smoothest route from an idea to a working web app for people who do not code. Describe what you want and it builds the interface, database, logins and hosting, with its own backend or a Supabase connection, and you can sync the code to GitHub. The free plan is enough to try it, Pro costs €25 a month including VAT for 100 credits that roll over for a month, and Business €50. Students can get up to 50% off Pro.
Bolt.new runs a full development environment in the browser and keeps the code visible, which suits people who can read code and want to adjust it. The free plan allows 300,000 tokens a day and 1 million a month. Pro costs $25 a month with no daily limit, starting at 10 million tokens that roll over to the next month, and Teams costs $30 per member. Our Lovable vs Bolt comparison covers the choice between them.
v0 by Vercel generates polished React and Next.js interfaces and full apps, and deploys straight to Vercel. The free plan includes $5 of credits a month with a limit of 7 messages a day. Plus costs $30 per user a month with $30 of credits plus $2 of free credits each day you log in, and Business $100 per user. Credits are consumed by tokens, so long conversations about large projects cost more than short ones.
Replit combines a cloud IDE, its Agent and hosting in one place, so an app can be built, run and published without leaving the browser. Core costs $20 a month, or $18 billed yearly, and Pro $100 ($90 yearly) with ten parallel agents, scaling to plans of up to $2,000 a month for heavy use. It suits people who want everything, including the database and deployment, managed in one account.
More AI-written code means more code to review, and review tools have become part of the stack. CodeRabbit comments on pull requests like a reviewer, is free for public repositories and has paid plans for private code. Cursor's Bugbot, Copilot's code review and Codex's GitHub reviews do the same inside their own products, so a team paying for one of those may not need a separate reviewer.
Whatever the tool, the checks that matter do not change: run the tests, read the diff, and treat anything touching authentication, payments or data deletion as code a person must understand before it ships.
Several names from older lists have changed. The company behind Codeium renamed itself Windsurf in 2025, OpenAI's planned purchase of it fell through that July, and Windsurf ended up with Cognition, which renamed the editor Devin Desktop in June 2026; the Codeium brand is discontinued. Tabnine is now owned by Tricentis and sells by quote rather than a public price list. Continue.dev, once a popular open-source assistant, is no longer maintained. Guides that still recommend these tools under their old terms are out of date.
Nothing at all. GitHub Copilot Free for completions in your IDE, plus Gemini CLI or Gemini Code Assist for agent work, covers a surprising amount. Add Cline with an inexpensive model when you want more control.
About $20 a month. Pick one subscription by how you work: Cursor Pro if you want an AI editor, Claude Pro if you want to delegate tasks to Claude Code, or ChatGPT Plus if you also want ChatGPT's images and voice along with Codex. Copilot Pro at $10 is the cheaper alternative to Cursor for AI inside your existing IDE.
About $40 a month. An editor plus an agent: Cursor Pro or Copilot Pro alongside Claude Pro is a common pairing, with the editor for hands-on work and Claude Code for larger tasks. Non-developers building products are better served by Lovable Pro or Bolt.new Pro, paired with a general assistant for planning.
The expensive tiers, from $100 to $200 a month, are worth it only once you hit the limits of a $20 plan regularly. All of the paid tools above have a free plan or trial, so the cheapest mistake to avoid is paying for a year before a week of real use.
It depends on how you want to work. For an AI-first editor, Cursor. For AI inside the IDE you already use at the lowest price, GitHub Copilot at $10 a month. For handing whole tasks to an agent in the terminal, Claude Code, included in Claude Pro at $20. For building an app without writing code, Lovable or Bolt.new.
Several. GitHub Copilot Free gives 2,000 completions a month plus limited chat and agent use. Gemini Code Assist is free for individual developers with high limits, and Google's Gemini CLI is open source. Cline and Aider are free and open source, so you pay only for the model API you connect. Cursor, Devin Desktop and Kiro also have free tiers with light quotas.
They do different jobs, and many developers use both. Cursor is an editor where you write code with AI beside you, with autocomplete, inline edits and an agent. Claude Code is an agent you hand a task to in the terminal, which plans, edits files, runs tests and reports back. Cursor Pro and Claude Pro each cost $20 a month.
OpenAI agreed to buy Windsurf in 2025, but the deal fell apart in July of that year. Google then hired its chief executive and some staff, and Cognition, the company behind the Devin agent, bought the rest of the business. Cognition renamed the editor Devin Desktop on June 2, 2026, keeping its plans: free, Pro at $20 and Max at $200.
Lovable is the easiest start for people who do not code: describe an app and it builds the interface, database and login, with a free plan and Pro at €25 a month. Bolt.new suits people who want to see and edit the code, with Pro at $25 for 10 million tokens. v0 by Vercel is strongest for polished React interfaces.
