Why Cursor wins this benchmark
Cursor won because it is the most complete assistant, not the best at any single criterion: strong inline completions, a capable multi-file agent, model choice across labs, and a documented privacy mode, all in one editor. GitHub Copilot finished one point behind with the best autocomplete, the lowest price, and the broadest editor support, which makes it the better pick if you will not leave VS Code, Visual Studio, or a JetBrains IDE. Claude Code leads on agent work and codebase understanding; if you mostly hand whole tasks to an agent rather than type code with suggestions, choose it, and note that it does not do inline autocomplete.
- ▸The only tool we scored that is strong at both halves of the job: fast inline completions while you type and multi-file agent edits you review as diffs
- ▸Model choice across several frontier providers inside one editor, so you can switch when a new model lands
- ▸Privacy mode is a documented guarantee: when it is on, code data is not used for training by Cursor or its model providers
How each criterion was scored
The overall ranking above is an equal-weighted sum of 6 criteria. Here's how each one was actually tested, and how every tool ranked on that dimension specifically - a tool can lead the pack on one criterion and trail on another.
Agent & Multi-File Work
This is the job that separates assistants from autocomplete. Claude Code leads: it is built to take a bug fix, a test suite, or a migration and work through it from the terminal, IDE, web, or GitHub. Cursor, Windsurf (Devin Desktop), and OpenAI Codex are close, with agents in the editor, the cloud, and the CLI. Cline is a capable open-source agent that asks approval at every step. Antigravity's agents are newer, Copilot's agent mode is solid but less polished in the reviews we read, and JetBrains AI's agent features trail the dedicated tools.

|---|---|---|---|---|---|---|---|
| 10/10 | 9/10 | 9/10 | 8/10 | 8/10 | 7/10 | 7/10 | 6/10 |
Autocomplete & Everyday Editing
GitHub Copilot leads because inline completion is what it was built around, and it works in VS Code, Visual Studio, JetBrains, Vim, and Neovim. Cursor and Windsurf (Devin Desktop, which offers unlimited Tab completions even on its free plan) are right behind. JetBrains AI is good where it is available. Antigravity offers unlimited Tab completions on its free plan. Claude Code, OpenAI Codex, and Cline are agents rather than autocomplete engines and score lowest here.

|---|---|---|---|---|---|---|---|
| 10/10 | 9/10 | 9/10 | 8/10 | 7/10 | 5/10 | 5/10 | 5/10 |
Codebase Understanding
Claude Code and Cursor lead: both are repeatedly singled out in the reviews we read for investigating a repository before editing it, and Claude Code is aimed at large or unfamiliar codebases. JetBrains AI benefits from the IDE's own index and refactoring tools, which gives it an advantage inside JetBrains projects. Codex and Windsurf (Devin Desktop) are solid. Copilot, Cline, and Antigravity are adequate but depend more on the open files and the model you pick.
| #1Claude Code | #2Cursor | #3JetBrains AI | #4Windsurf (Devin Desktop) | #5OpenAI Codex | #6GitHub Copilot | #7Cline | #8Google Antigravity |
|---|---|---|---|---|---|---|---|
| 10/10 | 9/10 | 9/10 | 8/10 | 8/10 | 7/10 | 7/10 | 7/10 |
Model Choice & Flexibility
Cline leads: it works with any provider's API key, including local and open-weight models. Cursor, Windsurf (Devin Desktop), and GitHub Copilot offer frontier models from several labs; Devin Desktop can also run Codex and Claude Agent through the Agent Client Protocol. JetBrains AI and Antigravity offer several models and, in JetBrains' case, your own key. Claude Code only uses Anthropic's models and Codex only OpenAI's, which is why they score lowest.

|---|---|---|---|---|---|---|---|
| 10/10 | 9/10 | 9/10 | 8/10 | 7/10 | 7/10 | 5/10 | 5/10 |
Privacy & Team Controls
GitHub Copilot leads because Business and Enterprise add policy management, IP indemnity, and organization controls, and Cline's client-side design lets you pick the provider that sees your code. Cursor guarantees no training in Privacy Mode and adds SSO, audit logs, and access controls on Teams and Enterprise. Claude Code, Codex, and JetBrains AI have solid business tiers. One catch: GitHub says interactions on Copilot Free, Pro, and Pro+ may be used to improve its models unless you opt out, and Claude's consumer plans are opt-out for training too. Antigravity's controls are clearest on Google Cloud business plans.

|---|---|---|---|---|---|---|---|
| 9/10 | 9/10 | 8/10 | 8/10 | 8/10 | 8/10 | 7/10 | 5/10 |
Free Tier & Value
GitHub Copilot leads: a free plan with agent mode, then $10/month for Pro. Cline is free software where you pay only for model usage, Windsurf (Devin Desktop) and Antigravity have free plans with unlimited Tab completions, and Codex is included in ChatGPT plans from a free tier. Cursor's and Claude Code's paid plans are $20/month and metered, with heavier tiers at $100 to $200. JetBrains AI scores lowest because its free tier is only 3 credits a month and AI is bought on top of an IDE licence.

Individual tool reviews
Full breakdown for each tool tested - strengths, weaknesses, the one thing that trips people up, and current pricing.
Cursor
WinnerAn AI code editor (built on the VS Code foundation) with inline completions, multi-file agent edits, a CLI, cloud agents, and Bugbot code review, with a choice of frontier models.
Strengths
- +The only tool we scored that is strong at both halves of the job: fast inline completions while you type and multi-file agent edits you review as diffs
- +Model choice across several frontier providers inside one editor, so you can switch when a new model lands
- +Privacy mode is a documented guarantee: when it is on, code data is not used for training by Cursor or its model providers
Weaknesses
- -Premium model usage is metered, so the $20 headline price is the entry fee and heavy agent users end up on Pro+ or Ultra
- -You have to switch editors; if your team is committed to JetBrains or Visual Studio, it means leaving that IDE
- -The free Hobby plan is a trial of Agent mode, not a working allowance
Heads up: Privacy mode is something you turn on (or a team admin enforces), not the default. If your code is sensitive, enable it before the first prompt.
Hobby is free with limited Agent requests. Pro is $20/month and adds extended Agent limits, frontier models, MCPs, skills and hooks, and cloud agents; Pro+ and Ultra are higher-usage tiers for daily agent users. Teams is $40 per user per month and adds SSO, shared rules and plugins, and team-wide privacy mode. Every plan includes a set amount of model usage; after that, on-demand usage is billed in arrears (checked 3 October 2026).

GitHub Copilot
GitHub's assistant for VS Code, Visual Studio, JetBrains IDEs, Vim and Neovim, the GitHub website, the terminal, and a desktop app, with inline completions, chat, agent mode, and pull request review.
Strengths
- +Works inside the editor you already have: VS Code, Visual Studio, JetBrains IDEs, Vim, and Neovim, plus the terminal and GitHub itself
- +The lowest-priced paid plan in the category ($10/month) and a free plan that includes agent mode
- +Native tie-in to GitHub issues, pull requests, and code review, which no standalone editor matches
Weaknesses
- -Credit-based billing means model choice changes how far a plan goes; heavy agent users should watch the meter
- -Multi-file agent work is less polished than Cursor's or Claude Code's, according to the reviews we read
- -Interaction data from Free, Pro, and Pro+ users can be used to train models unless you opt out
Heads up: GitHub states that interactions on Copilot Free, Pro, and Pro+ (inputs, outputs, code snippets, and context) may be used to improve its models unless you opt out in settings. Business and Enterprise seats are separate.
Free is $0 with limited chat and agent usage and supports the CLI and agent mode. Pro is $10/month, Pro+ is $39/month, and Max is $100/month. Usage is paid for in GitHub AI Credits (1 credit = $0.01): Pro's $10 base is topped up with a variable flex allotment, and you can set a dollar budget for extra usage. Copilot Business is $19 per user per month (checked 3 October 2026).

Windsurf (Devin Desktop)
The AI IDE formerly called Windsurf, renamed Devin Desktop on 2 June 2026. It pairs a VS Code-compatible editor with an agent command center and runs Devin Local, Devin Cloud, and third-party agents such as Codex and Claude Agent.
Strengths
- +A free plan with unlimited Tab completions and inline edits, which is unusual in this category
- +Runs several agents side by side in one Kanban-style view, including Codex and Claude Agent through the open Agent Client Protocol
- +Backwards-compatible with VS Code extensions, keybindings, and Windsurf settings
Weaknesses
- -The product was renamed and re-priced in 2026, so most guides and reviews describe a version that no longer exists
- -The agent-manager approach is more to learn than a plain editor with chat
- -Premium usage is quota-based, and the free SWE-2 promotion ends on 16 October 2026
Heads up: Windsurf is now Devin Desktop and windsurf.com serves Devin's pricing. If an article quotes $15 or 500 credits for Windsurf Pro, it is describing the old plan.
Free is $0 with a light agent quota plus unlimited Tab completions and inline edits. Pro is $20/month with increased quotas and access to frontier models from OpenAI, Anthropic, and Google plus open-source models, and Max is $200/month. Teams is $80/month plus $40 per full seat. Extra usage is bought at API prices, and Cognition's own SWE-2 model is free in Devin Desktop and the CLI through 16 October 2026 (checked 3 October 2026). Older roundups still list Windsurf Pro at $15 with 500 credits; that is out of date.

Cline
An open-source coding agent for your editor and terminal that reads files, writes code, runs commands, and asks for your approval at each step, using your own API keys or Cline's provider.
Strengths
- +No lock-in: bring any provider's API key and switch models whenever a better or cheaper one ships
- +Every file edit and command needs your explicit approval, which makes the agent's work easy to audit
- +Open source, with a client-side architecture, a CLI, an SDK, and a desktop app for open-weight models
Weaknesses
- -Costs are usage-based, so a long agent session on a premium model can cost more than a flat $20 plan
- -It is an agent, not an autocomplete engine: its feature list does not include as-you-type Tab suggestions
- -The JetBrains extension is listed under the Enterprise plan on Cline's pricing page
Heads up: Cline is free, but the model is not. Set a spend limit with your provider before you hand it a large task.
The open-source extension is free for individual developers: no subscription or seat fee, you pay only for AI inference, either with your own API keys (OpenAI, Anthropic, Google, OpenRouter, AWS Bedrock, and others) or through Cline's provider at cost. Enterprise adds SSO, SCIM, audit logs, centralized billing, VPC deployment, and the JetBrains extension (checked 3 October 2026).
Visit Cline →
Claude Code
Anthropic's coding agent, run from the terminal, VS Code, JetBrains, the web, iOS, Android, GitHub, or Slack, that reads a codebase, edits files, runs tests, and works through multi-step tasks and migrations.
Strengths
- +The strongest fit for delegating a whole task: describe a bug fix, test suite, or multi-day migration and review the result
- +Reaches the same agent from the terminal, IDE extensions, web, mobile, GitHub, and Slack
- +Included in a $20 Claude subscription, so one plan covers coding and everything else Claude does
Weaknesses
- -No as-you-type autocomplete: it is built for larger tasks, not keystroke-level suggestions
- -Only Anthropic's models are available, so you cannot swap in a rival model
- -Usage limits are shared with chat and are not a fixed message count, so heavy days can hit the cap
Heads up: Claude Code and Claude chat draw from one usage pool. A long coding session can use up the allowance you wanted for everything else.
Not available on the free Claude plan. Claude Code is included in Pro ($17/month billed annually, or $20 billed monthly), Max (from $100/month for 5x or 20x Pro usage), and Team seats ($20 standard seat billed annually, $100 premium). Usage is shared with Claude chat and resets on a rolling 5-hour window with weekly limits on top; on paid plans you can turn on usage credits at API rates, or use API credits through a Console account (checked 3 October 2026).
Visit Claude Code →
JetBrains AI
AI chat, agents, and completions built into IntelliJ IDEA, PyCharm, WebStorm, and the other JetBrains IDEs, using the IDE's own code indexing and refactoring tools.
Strengths
- +Understands your project through the IDE's existing indexing, inspections, and refactoring tools, so suggestions fit how the project is structured
- +Lets you connect other agents and your own API key instead of only JetBrains' models
- +A credit meter you can read in dollars, with top-ups that do not expire for 12 months
Weaknesses
- -Only useful inside JetBrains IDEs; it does nothing for a VS Code team
- -The free tier is small (3 credits a month), and agent mode uses credits quickly
- -Agent features trail the dedicated AI editors in the reviews we read
Heads up: AI is bought separately from the IDE licence unless your plan bundles it. Check whether your All Products Pack already includes AI Pro before paying twice.
AI Free gives 3 AI Credits per 30 days, AI Pro is $10 for 10 credits, and AI Ultimate is $30 for 35 credits (individual pricing; organizations are priced separately). One credit equals $1 of usage, and you can top up credits that stay valid for 12 months. The All Products Pack includes the equivalent of AI Pro. As a rough guide, JetBrains says one credit buys about 10 AI Chat code-generation requests or about 40 in-editor generation requests (checked 3 October 2026).

OpenAI Codex
OpenAI's coding agent, available in the ChatGPT desktop app, the Codex CLI, an IDE extension, the web, and iOS, with cloud tasks, GitHub code review, and Slack and Linear integrations.
Strengths
- +Included in ChatGPT plans you may already pay for, from a free tier up to Pro
- +Runs the same agent locally (CLI, IDE, desktop) and as cloud tasks, and reviews GitHub pull requests
- +Worktrees, sandboxing and permission controls, subagents, and scheduled tasks are built in
Weaknesses
- -Only OpenAI models; you cannot swap in a model from another provider
- -No as-you-type autocomplete: it is an agent, not a Tab completer
- -Usage is variable and shared with ChatGPT, and OpenAI's own estimates span a 10x range
Heads up: Models change fast: OpenAI says GPT-5.5 retires from Codex on 14 October 2026, so guides that recommend it are already out of date.
Codex is included in ChatGPT Free (light use, desktop app), Go ($8/month), Plus ($20/month, with Codex on the web, CLI, IDE extension, and iOS), and Pro (from $100/month). Business is $20 per user per month billed annually ($25 monthly). Usage is shared with ChatGPT Work; OpenAI's own estimate for Plus is 15 to 160 local messages per 5 hours on GPT-6.1 Sol, depending on the task. You can also use an API key and pay API prices. GPT-5.5 retires from Codex on 14 October 2026 (checked 3 October 2026).

Google Antigravity
Google's agent-first development platform, with the Antigravity IDE, CLI, SDK, and extensions, running Gemini models plus Anthropic and open-weight models on its free plan.
Strengths
- +A free plan that includes Claude and Gemini models, unlimited Tab completions, and command requests
- +One platform across IDE, CLI, SDK, and IDE extensions
- +Business and Cloud customers get spend caps and central admin controls
Weaknesses
- -Weekly rate limits on the free plan are basic, and Google does not publish the numbers on the pricing page
- -It is new and moving quickly, so there is little long-term track record or independent review data
- -Paid plan prices are not shown on the Antigravity page and the product line has been reshuffled (Gemini Code Assist's free individual tier is being replaced by it)
Heads up: Qodo reports that Google has told users of the free Gemini Code Assist IDE extensions and Gemini CLI to migrate to Antigravity. If you rely on those, plan the move.
The individual plan is $0 with access to Gemini 3.8, 3.7, and 3.6 Flash, Gemini 3.1 Pro, Claude Sonnet and Opus 4.6, and gpt-oss-120b, plus unlimited Tab completions and command requests under basic weekly rate limits. Google AI Pro and Google AI Ultra raise the rate limits and add a flexible credit pool; Google does not show their prices on the Antigravity page. Business access comes through Google Cloud (checked 3 October 2026).

GitHub Copilot is one point behind and costs less; Claude Code is best for handing off whole tasks.
Is GitHub Copilot or Cursor better?
Cursor scored 51/60 and Copilot 50/60. Pick Cursor if you want the strongest multi-file agent and are happy to switch to its editor. Pick Copilot if you want the best autocomplete, the lowest price ($10/month Pro), or to stay in VS Code, Visual Studio, or a JetBrains IDE. Both have a free plan.

GitHub Copilot Free is the best free option: it costs $0, supports the CLI and agent mode, and runs in your current editor, though usage is limited. Windsurf (Devin Desktop) and Google Antigravity also have free plans with unlimited Tab completions, and Cline is free software where you pay only for the model you connect.
What is the best AI coding assistant for VS Code?
GitHub Copilot, because it is built for VS Code, has the best inline completions, and starts at $0. If you are willing to move to a VS Code-compatible editor, Cursor and Windsurf (Devin Desktop) give you stronger agents. Cline and Claude Code also run inside VS Code as extensions.
What is the best AI coding agent?
Claude Code scored highest on agent work (10/10) and codebase understanding: you describe a task and it edits files, runs tests, and iterates. Cursor and OpenAI Codex are close behind. None of the three is cheap at heavy use, so watch the usage limits on your plan.
Is Windsurf still available?
Windsurf was renamed Devin Desktop on 2 June 2026 by Cognition. Existing Windsurf users received it as an update, and windsurf.com now shows Devin's pricing: Free, Pro at $20/month, and Max at $200/month. Guides that list Windsurf Pro at $15 with 500 credits are out of date.
Is Amazon Q Developer still worth using?
Not as a new choice. Qodo reports that AWS has posted an end-of-support notice for Amazon Q Developer's IDE plugins effective 30 April 2027 and points users to Kiro. We left it out of the ranking for that reason; verify the current status with AWS before you adopt it.
Does GitHub Copilot train on my code?
GitHub says interactions from Copilot Free, Pro, and Pro+ users, including inputs, outputs, code snippets, and context, may be used to improve its models unless you opt out. Business and Enterprise seats are handled separately. Cursor's Privacy Mode guarantees no training on code data, and Cline sends code only to the provider you choose.
How much does an AI coding assistant cost?
Most working plans cost $10-20 a month: GitHub Copilot Pro $10, JetBrains AI Pro $10, Cursor Pro $20, Windsurf (Devin Desktop) Pro $20, Claude Pro $20 monthly ($17 annual) with Claude Code included, and ChatGPT Plus $20 with Codex included. Heavy agent users move to $100-$200 tiers, and Cline is free software where you pay only for model usage. Prices checked 3 October 2026.
