What is the best AI for coding right now?

For most developers it comes down to Cursor (a full AI IDE) and Claude Code (a terminal agent), with GitHub Copilot the safe default if you are already on GitHub. The right pick depends on whether you want an IDE, a terminal agent or a browser builder — the table on this page compares all of them on the facts. Our numerical scores are from a real test that is still being finalised.

What is the difference between an AI coding assistant and a vibe coding tool?

An AI coding assistant (Cursor, Claude Code, Copilot) helps you write and edit code inside an IDE or terminal — you still own the codebase. A vibe coding tool (Lovable, Bolt, v0) builds a whole app or site from prompts, often with little or no code-touching. If you want to ship an app without managing the code, see our best vibe coding tools guide.

Is there a good free AI for coding?

Yes. GitHub Copilot, Gemini Code Assist, Windsurf and Cursor all have free tiers, and tools like the OpenAI Codex CLI are open source. Free tiers usually cap usage or model access, so check the current limits on each vendor’s site — “free” sometimes means a trial in disguise.

Do these tools work with my IDE?

It varies by tool. Copilot, Gemini Code Assist and Amazon Q ship as extensions for VS Code and JetBrains. Cursor, Windsurf and Zed are standalone editors. Claude Code and the Codex CLI run in the terminal. The “Form factor” row in the comparison shows exactly how each one is delivered.

How do you score these tools?

We run the same set of real tasks through every tool on our own repositories, screenshot what we see, and score across weighted dimensions — see How We Test for the full method. Scores publish only after that hands-on testing is complete, so any tool still marked “in progress” has no fabricated number attached.

01 / The tools

Ranked by our score

Claude Code

Anthropic’s agentic coding tool that runs in your terminal (and IDE).

9/10

CLI · Extension
No free tier
From $20/mo
MCP

Models Claude

Best for

Terminal-centric developers
Agentic, multi-step refactors

Terminal-native agentic coding that makes multi-step refactors and big changes the least painful — once you settle into a CLI workflow.

Pros

Strong at autonomous, multi-step agent tasks
Works in the terminal and as IDE extensions
Solid context and memory handling
MCP support for connecting external tools

Cons

No free tier — subscription or usage-based
Pure-CLI flow has a learning curve for IDE users
Token usage adds up on complex tasks

OpenAI Codex CLI

OpenAI’s open-source agentic coding CLI (with a cloud counterpart).

9/10

CLI
Free tier
Usage / plan-based
MCP

Models GPT / Codex

Best for

Terminal developers in the OpenAI ecosystem

An open-source agentic CLI for people who want to stay in the GPT/ChatGPT ecosystem but still get a real terminal agent.

Pros

Open source — self-hostable and auditable
Integrates cleanly with the OpenAI ecosystem
Terminal-first agent workflow
Runs on a ChatGPT Plus/Pro plan or API usage

Cons

Smaller ecosystem and plugin set than Cursor
CLI-first flow has a learning curve
Capability shifts with the underlying GPT/Codex version

Cursor

AI-first IDE (a VS Code fork) with multi-file agent editing.

8/10

IDE
Free tier
From $20/mo
MCP

Models Claude, GPT, Gemini, Cursor models

Best for

Full-time developers who live in an IDE
Large existing codebases

The default pick for IDE-based developers — multi-file agent edits across a large codebase feel the most natural, with near-zero ramp on top of VS Code.

Pros

Almost no learning curve on top of VS Code
Strong multi-file agent editing
Model choice (Claude / GPT / Gemini)
Handles large-codebase context well

Cons

Pro quota feels tight under heavy use
Occasionally over-eager with edits
IDE-only — no native CLI flow

Last tested: 2026-06-18

Windsurf

Agentic IDE (formerly Codeium) built around its Cascade agent.

7/10

IDE · Extension
Free tier
From $20/mo
MCP

Models Claude, GPT, Gemini, SWE-1

Best for

Developers who want an agent-first IDE flow

An agent-first IDE — the Cascade flow is smooth; it sits in the same tier as Cursor, so it comes down to personal feel.

Pros

Smooth Cascade agent flow
Agent-first design
Has a free tier
Model choice (Claude / GPT / Gemini)

Cons

Ecosystem and plugins less mature than Cursor
Went through rebrand turbulence (Codeium → Windsurf)
Large-codebase results vary by scenario

GitHub Copilot

The incumbent AI pair-programmer, embedded across major IDEs.

6/10

Extension · IDE · CLI
Free tier
From $10/mo
MCP

Models GPT, Claude, Gemini

Best for

Teams already on GitHub
Multi-IDE shops

The steady incumbent — deeply embedded across IDEs and the GitHub ecosystem, easiest for team standardization; agent autonomy trails the newer tools.

Pros

Deeply embedded in VS Code, JetBrains and more
Native to the GitHub ecosystem
Low entry price (~$10) with a free tier
Model choice (GPT / Claude / Gemini)

Cons

Agent autonomy lags Cursor and Claude Code
Tends to follow rather than lead on features
More conservative on complex multi-step tasks
