GITHUB / MICROSOFT

GitHub Copilot

OFFICIAL SITE ↗

The default autocomplete for millions of developers. Cheapest mainstream Pro plan, works in the editor you already use, and Copilot Chat / agent covers multi-file edits.

What is an AI coding assistant?

An AI coding assistant sits in your editor or terminal and helps you write, explain, refactor and debug code. Some only autocomplete the next line. Others can open files, run tests and finish a whole task (that is agent mode).

How to use this comparison

  1. Use the filters (free plan, under $15, agent mode, open source, IDE type).
  2. Click a card to see pricing, models and the best-fit user.
  3. Open the vendor site from the card when you are ready to try it. This page does not sign you up for anything.

Three ways these tools charge

  • Subscription: Copilot, Cursor, Windsurf — a monthly fee includes a quota of model calls.
  • Bundled chat plan: Claude Code rides on Claude Pro / Max; Codex rides on ChatGPT Plus / Pro.
  • BYOK (bring your own key): Cline, Aider and Continue.dev are free apps. You pay the model API directly (or run a local model).

How to choose

  • Stay in VS Code / JetBrains: GitHub Copilot or Continue.dev.
  • Want an AI-native IDE: Cursor or Windsurf (both are VS Code forks).
  • Live in the terminal: Claude Code, Aider or Gemini CLI.
  • Privacy / local models: Continue.dev, Cline or Tabnine.
  • Lowest cash outlay: Gemini CLI, Continue.dev + a cheap API, or Copilot's limited free tier.

Frequently Asked Questions

What is the best free AI coding assistant?+

It depends on the surface. Gemini CLI and Continue.dev (with your own key or a local model) cost $0 for the app. GitHub Copilot, Cursor and Windsurf offer limited free tiers. Cline and Aider are open source — you only pay the model API, or nothing if you run Ollama locally.

Cursor vs GitHub Copilot: which should I pick?+

Copilot is cheaper ($10/mo Pro), works inside the editor you already use and is the safest default for teams on GitHub. Cursor is a full AI IDE (~$20/mo) with a stronger agent/composer workflow for multi-file refactors. Try Copilot first if you do not want to switch editors.

What does BYOK mean?+

Bring Your Own Key. The coding tool is free; you paste an API key from OpenAI, Anthropic, Google or a local server. You pay per token to that provider. Use the AI Cost Calculator on this site to estimate that bill.

What is agent mode?+

Autocomplete suggests the next line. Agent mode can plan a change, edit several files, run commands and loop on errors. Cursor, Windsurf, Claude Code, Cline and Copilot all offer some form of agent. Quality and how much you can steer them still differ.

Do these tools train on my private code?+

Policies differ. Business/enterprise plans usually offer no-training and data-retention controls. Open-source BYOK tools only send code to the model provider you chose (or nowhere, if the model is local). Read the vendor privacy page before pasting secrets or proprietary repos.

Is this comparison affiliated with any vendor?+

No. It is an independent, client-side overview. Prices and features change — confirm on the official site. We do not collect emails or take a cut if you subscribe.
