AI coding assistants have moved far beyond autocomplete. In 2026 the leading tools are agents: they read your codebase, plan a change across many files, run tests and open a pull request. They are also priced very differently, from free to $200 a month.
We compared the six assistants developers talk about most, using each vendor's official pricing page, product documentation and recent independent comparisons (sources at the end). Prices were checked in October 2026.

How we chose
- We looked only at tools that are actively developed and widely used in 2026.
- Each tool was compared on agent capability (multi-file edits, running commands, opening PRs), editor support, pricing and limits, and model choice.
- Facts come from official pricing and product pages; rankings are our editorial judgement based on that research and independent comparisons. Read our review process.
1. Claude Code: best coding agent
Claude Code
Best coding agentAnthropic's Claude Code is an agent that lives in your terminal and IDE. You describe a task, and it explores the repository, edits files, runs your tests and iterates until the job is done. Independent comparisons consistently rank it, alongside Codex, as one of the two most complete coding agents available.
- Very strong at planning and executing multi-file changes
- Works in the terminal, VS Code, JetBrains, desktop and web
- Hooks, skills and scheduled tasks for automation
- No free tier for Claude Code
- Heavy users will need the $100+ Max plan
Claude Code is included in Claude Pro ($20/month or $17/month billed yearly) and Max (from $100/month for 5× or 20× Pro usage). It is not available on the free Claude plan.
2. Cursor: best AI code editor
Cursor
Best AI editorCursor is an AI-first fork of VS Code and is widely regarded as the strongest AI-native editor. After its parent company Anysphere was acquired by SpaceX in August 2026, Cursor moved to new plans that share usage with Grok.
- Polished VS Code-based editor with deep AI integration
- Cloud agents, automations and Bugbot code review on Premium
- Excellent tab completion and multi-file edits
- Pricing changed significantly after the SpaceX/xAI acquisition
- Third-party models are billed separately at API prices
- The $8 Plus plan only includes Grok models
The new line-up is Free, Plus ($8/month, Grok models only), Premium ($30/month, 4× Plus usage, cloud agents and Bugbot), Super ($100/month) and Ultra ($200/month). On Premium and above, Claude, GPT and Gemini models are available but billed separately at API list prices, so check the pricing page before you commit.
3. GitHub Copilot: best value
GitHub Copilot
Best valueGitHub Copilot is the easiest assistant to adopt: it plugs into VS Code, JetBrains, Visual Studio and the terminal, and integrates tightly with GitHub issues, pull requests and code review.
- Cheapest serious paid plan at $10/month
- Works in almost every editor plus the CLI and GitHub.com
- Access to 30+ models from Anthropic, OpenAI, Google and others
- Cloud agent turns issues into pull requests
- Free plan caps inline suggestions at 2,000 per month
- Delegating to Claude or Codex agents needs Pro+ or Max
Copilot now uses AI credits (1 credit = $0.01). Pro ($10/month) includes $15 of credits, the cloud agent and pull-request code review. Pro+ ($39/month) adds delegation to third-party agents like Claude and Codex, and Max ($100/month) includes $200 of credits.
4. OpenAI Codex: best if you already pay for ChatGPT
OpenAI Codex
Best for ChatGPT usersCodex is OpenAI's coding agent. It is not sold separately for interactive use; instead it is bundled into ChatGPT plans and works across the web app, a CLI, IDE extensions and iOS.
- No extra subscription if you already have ChatGPT Plus
- Runs locally in the CLI/IDE or as cloud tasks
- One of the most capable agents in independent comparisons
- Cloud tasks are limited per 5-hour window on Plus
- Go plan does not unlock cloud task delegation
If you already pay $20/month for ChatGPT Plus, Codex is effectively free to try. The $100 Pro plan (launched April 2026) gives 5× Plus's Codex usage, and the $200 Pro plan gives 20×.
5. Google Antigravity: best free option
Google Antigravity
Best freeAntigravity is Google's agent-first development environment. Google's newest Gemini 4 Argon model arrived there first for Ultra subscribers in October 2026.
- Genuinely usable free tier with unlimited tab completions
- Agent-first desktop app and CLI
- Higher limits come with Google AI Pro (which also includes 5 TB storage)
- Free tier drops non-Gemini models on November 2, 2026
- Quota is based on agent work, so limits can be hard to predict
6. Devin Desktop (formerly Windsurf): best for running many agents
Devin Desktop
Cognition renamed Windsurf to Devin Desktop in June 2026. It keeps the Windsurf editor and adds a command center for running and reviewing multiple local and cloud agents.
- Agent command center with Kanban view for many agents
- Local and cloud sessions with shared context
- Supports third-party agents via Agent Client Protocol
- Recent rename and agent changes mean older tutorials are outdated
- Big jump from $20 Pro to $200 Max
How to choose the right AI coding assistant
Agent or editor?
If you want an assistant that takes a task and finishes it, choose an agent such as Claude Code or Codex. If you prefer to stay in control and accept suggestions as you type, an AI editor like Cursor or Copilot in VS Code will feel more natural. Many developers use one of each.
Check how usage is measured
Every tool now meters usage differently: Copilot uses AI credits, Cursor shares a usage pool with Grok, and Claude, ChatGPT and Google plans use rolling limits. Start on the cheapest plan and upgrade only when you hit limits.
Privacy and company code
Before using any assistant on work code, check your employer's policy and the vendor's data-retention terms. Business and Enterprise plans usually add admin controls, SSO and stricter data handling.
