How to choose an AI coding assistant
Start with how much you want to hand off. Inline assistants suggest code as you type; coding agents take a task, change files across your project and run commands. Try one real task from your own codebase on a free plan or for a single month before you sign up a whole team.
You want to hand off whole tasks
Claude Code plans a change, edits files across your project and runs commands, from the terminal, VS Code, JetBrains, its desktop app or the browser. It needs a paid Claude plan, from $17 a month billed yearly. OpenAI Codex does the same job for ChatGPT subscribers, with an open-source CLI. CLI and IDE use start with ChatGPT Plus, at $20 a month.
You want help as you type, in the editor you use
GitHub Copilot works in VS Code, JetBrains IDEs and other editors. Code completions are unlimited on every paid plan, and the free plan includes 2,000 a month. Paid plans also review your pull requests. Since June 1, 2026, chat and agent use draw on monthly AI Credits, so heavy agent users should watch their balance in their first month.
You'd like an editor built around AI
Cursor is a full code editor built around AI agents. It has new plans since October 13, 2026: Plus, at $8 a month, uses Grok models only. Models from other AI companies need Premium, at $30 a month, and are billed by usage at API rates on top. OpenAI has said its models will leave Cursor on November 12, 2026. Google Antigravity is a free agent-first editor with weekly rate limits, raised with a Google AI Pro plan. Devin Desktop, formerly Windsurf, runs Devin's local agent in the editor, with Devin usage included in paid plans from $20 a month.
You want open source and your own model keys
Cline is a free, open-source coding agent that runs as a VS Code extension or a CLI. You bring your own key from OpenAI, Anthropic or Google, or pay for AI usage at cost, so your bill follows how much you use it. The Codex CLI is open source as well, and works with your ChatGPT plan.
Your team wants a review on every pull request
CodeRabbit reviews each pull request and can also check code in your IDE or CLI before you open one. Its free plan summarizes pull requests, open-source projects get Team features for free, and paid plans start at $24 per developer a month billed yearly. It reviews pull requests whichever tool wrote the code.
Windsurf is now Devin Desktop
Windsurf was renamed Devin Desktop on June 2, 2026, and windsurf.com now leads to Devin's site. Existing users received it as an update with the same plan and price. Devin's Pro plan includes a Windsurf IDE quota alongside Devin usage. Our Windsurf review was written before the change.
AI coding assistants FAQ
What is the best AI coding assistant in 2026?
Claude Code is the best AI coding assistant in our October 2026 rankings, at 4.8 out of 5, for handing off multi-step tasks from the terminal or your editor. OpenAI Codex (4.7) is our pick if you already pay for ChatGPT, and GitHub Copilot (4.6) suits teams that want AI inside the editors they use. For reviews on every pull request, CodeRabbit (4.6) is our top pick.
Is there a free AI coding assistant?
Yes. GitHub Copilot has a free plan with 2,000 code completions and 50 chat requests a month. Google Antigravity is free with weekly rate limits. Cline is free and open source; you pay only for AI usage. ChatGPT's Free plan includes Codex for quick tasks, and Cursor and Devin Desktop have limited free plans. Claude Code is the exception: it needs a paid Claude plan.
What is the difference between an AI coding assistant and an AI coding agent?
An AI coding assistant such as GitHub Copilot mainly helps while you type, with suggestions and answers in a chat panel. An AI coding agent such as Claude Code or OpenAI Codex takes a task, reads the relevant code, changes several files and runs commands until the job is done. Most tools on this page now do both, so pick by how much you want to hand off.
Should I use Claude Code or GitHub Copilot?
Choose Claude Code if you want to hand off whole tasks, such as a feature or a set of failing tests, and review the result. Choose GitHub Copilot if you want suggestions as you type in your current editor and admin controls for a team on GitHub. You can also use both: Copilot for everyday edits, and an agent for the larger jobs.
What happened to Windsurf?
Windsurf was renamed Devin Desktop on June 2, 2026, and windsurf.com now leads to Devin's site. Existing users got the change as an update and kept the same plan and price. Devin's local agent now works inside the editor. There is a limited free plan, and paid use starts with Pro at $20 a month.
Why aren't Tabnine, Amazon Q Developer or Blackbox AI on this list?
Tabnine, Amazon Q Developer and Blackbox AI have each changed in ways that matter for new users. Tabnine now offers Enterprise plans only. AWS has closed new Amazon Q Developer sign-ups and recommends Kiro, with the IDE plugins supported until April 30, 2027. Blackbox AI now focuses on an enterprise AI platform and has discontinued its VS Code integration. We list tools an individual developer can sign up for today.
How should I check code written by an AI coding assistant?
Treat code from any AI coding assistant like code from a new teammate, and add a review tool such as CodeRabbit for a second pass on each pull request. Run your tests and read every change before you merge it. Keep production secrets out of the agent's reach. AI review supports a human review rather than replacing it.
