AI coding tools

How to choose

• If you want to write code with an AI agent: Cursor — watch out: pricing page now bundles Cursor with Grok/X subscription tiers, which can be confusing.
• If you want to autocomplete code: GitHub Copilot — watch out: best value if your code already lives on GitHub.
• If you want to agentic coding in the terminal: Claude Code — watch out: usage limits depend on plan.
• If you want to delegate engineering tasks to a cloud agent: Devin (incl. Devin Desktop, formerly Windsurf) — watch out: free quota is light.
• If you want to open-source coding agent in VS Code: Cline — watch out: you pay model inference costs directly.
• If you want to AI pair programming in the terminal: Aider — watch out: latest GitHub release found was v0.86.0 (Aug 2025), so check activity.
• If you want to fast code editor with AI: Zed — watch out: smaller extension ecosystem than VS Code.
• If you want to cloud coding agents: OpenAI Codex — watch out: usage tied to ChatGPT plan limits.
• If you want to full-stack app in the browser: Firebase Studio — watch out: backend costs follow Firebase/Google Cloud pricing.
• If you want to AI code review on pull requests: CodeRabbit — watch out: per-user pricing.
• Starting free: Cursor, GitHub Copilot, Devin (incl. Devin Desktop, formerly Windsurf), Cline, Aider, Zed, Firebase Studio list a free tier or open-source option.
• Paid or trial only: Claude Code, OpenAI Codex, CodeRabbit — compare the pricing sources below before committing.
