Quick comparison
| Tool | Best for | Free tier | Starting price | Fit / Verdict |
|---|---|---|---|---|
| Aider | CLI-first, Git-aware multi-file edits | Free options with limits, works with local models | Open source; pay for LLM API tokens | Best for terminal workflows |
| GitHub Copilot | IDE integration, GitHub-centric workflows | 2,000 completions/month | $10/month (Pro) | Best for in-editor assistance |
| Cursor | AI-native editor, multi-file agentic workflows | Free | Plus $8/month; Premium $30/month | Best for AI-native editing |
Aider: CLI-First with Multi-File Prowess
Aider is an open-source AI coding assistant designed for developers who prefer a terminal-based workflow. It shines in its ability to handle multi-file edits and its deep integration with Git, making it a strong contender for those who want their AI pair programmer to be highly context-aware of their codebase.
Pricing: Aider is open source under Apache 2.0 and charges no subscription. You pay the model provider for API tokens, or run a local model (checked 2026-10-02: aider.chat/docs/faq.html, aider.chat/docs/llms.html).
When to choose Aider: Choose Aider if you are a CLI-first engineer seeking a Git-aware pair programming experience with multi-file editing capabilities and the flexibility to choose your LLM.
When not to choose Aider: Aider is not ideal for developers who prefer a graphical user interface (GUI) or deep integration within a traditional IDE without a terminal overlay.
GitHub Copilot: Seamless IDE and GitHub Integration
GitHub Copilot offers in-editor code completion and chat, providing code suggestions across multiple languages and assistance with repository and pull request workflows. It’s built for seamless integration within popular IDEs like VS Code and JetBrains, making it a natural fit for developers already working within the GitHub ecosystem.
Pricing: GitHub Copilot Free includes 2,000 completions per month, plus a limited allowance of chat and agent usage [https://docs.github.com/en/copilot/get-started/plans] (checked 2026-10-01). Paid plans include unlimited code completions.
- Pro: $10/month, 1,500 GitHub AI credits (1,000 base plus 500 flex) [https://docs.github.com/en/copilot/get-started/plans] (checked 2026-10-01).
- Pro+: $39/month, 7,000 GitHub AI credits (3,900 base plus 3,100 flex) [https://docs.github.com/en/copilot/get-started/plans] (checked 2026-10-01).
- Max: $100/month, 20,000 GitHub AI credits (10,000 base plus 10,000 flex) [https://docs.github.com/en/copilot/get-started/plans] (checked 2026-10-01).
- Business: $19 per seat per month, 1,900 GitHub AI credits per user [https://docs.github.com/en/copilot/get-started/plans] (checked 2026-10-01).
- Enterprise: $39 per seat per month, 3,900 GitHub AI credits per user [https://docs.github.com/en/copilot/get-started/plans] (checked 2026-10-01).
When to choose GitHub Copilot: GitHub Copilot is ideal for developers who want always-on IDE assistance, particularly those deeply embedded in GitHub-centric workflows using VS Code or JetBrains.
When not to choose GitHub Copilot: It is not for teams seeking a Git-aware CLI agent or for those prioritizing AI-native editors that offer a more agent-first development experience.
Cursor: The AI-Native Code Editor
Cursor is an AI-native code editor built on VS Code, designed for multi-file agentic workflows and codebase-wide chat. It provides inline edits and terminal-aware assistance, aiming to streamline the development process with powerful AI capabilities directly within the editor.
Pricing: Checked 15 October 2026 on cursor.com/pricing. New customers buy The X Subscription: Free, Plus $8/month, Premium $30/month, Super $100/month, and Ultra $200/month. Teams starts at $30 per user per month. Paid plans share one weekly usage pool across Cursor and Grok. Plus includes Grok models only. On Premium and above, third-party models are billed at API list price from the first request and are not included in the monthly price. Legacy Hobby, Pro ($20/month), Pro+ ($60/month), Ultra ($200/month), Teams Standard ($40/user/month), and Teams Premium ($120/user/month) continue for existing subscribers until they switch or cancel (legacy plans).
When to choose Cursor: Choose Cursor if you prioritize an AI-native code editor with advanced multi-file agent edits and comprehensive codebase chat functionalities.
When not to choose Cursor: Cursor may not be the best fit for teams whose existing editor-switching costs or entrenched workflows outweigh the benefits of adopting an agent-first development experience.
Claude Code and Codex
Claude Code and Codex are agent harnesses, not extra columns on the editor table. The price follows the subscription you already pay. These figures match Claude Code vs Codex, checked 2026-10-11.
Claude’s pricing page, rechecked 15 October 2026, includes Claude Code on Pro, Max, Team, and Enterprise, and not on Free. Pro is $17/month billed annually ($200 up front) or $20 billed monthly. Max 5x is $100/month and includes $100/month in Claude Platform API credits. Max 20x is $200/month and includes $200/month in those credits. Pro does not. Claude Code draws from the same pool as chat. Cowork is not named on the pricing page. Anthropic says Cowork and chat are merging into one Claude on Pro and Max (Cowork is now Claude).
OpenAI’s Codex page includes Codex in the ChatGPT plan. Plus is $20 for focused coding sessions. The Pro card on that page is $100, for higher limits across a workday. OpenAI’s Pro tiers article also lists Pro 200 at $200/month and Pro 500 at $500/month. Business is $20 per seat billed annually for two or more seats.
Stay on Claude Code if the seat is already Claude. Stay on Codex if the seat is already ChatGPT. For the editor-versus-harness cut, see Cursor vs Claude Code.
Windsurf is now Devin Desktop
Windsurf is now Devin Desktop. Cognition renamed the IDE on 2 June 2026: same editor, and existing plans carry over (Windsurf is now Devin Desktop). It is billed on the Devin plan sheet: Free, Pro $20/month, Max $200/month, and Teams $80/month plus $40 per full seat, on a daily and weekly quota rather than prompt credits. Those plan prices were checked 2026-10-01 on devin.ai/pricing. The editor comparison stays Windsurf vs Cursor. The shortlist of ways off Cursor is Cursor alternatives.
Making Your Decision
There is no single winner. Aider is the CLI pair programmer. GitHub Copilot remains the pick for GitHub-native teams that want the assistant inside VS Code or JetBrains. Cursor remains the pick for AI-native editing. Claude Code and Codex are the harnesses on the plan you already pay for.
