AI Coding Tools Compared: Copilot vs Cursor vs Codeium

AI coding tools have gone from novelty to essential in about 18 months. The question isn't whether to use one — it's which one. We tested the three most popular options on real TypeScript, Python, and Go projects.

GitHub Copilot: The established choice

GitHub Copilot ($10/month) is the most mature option. Its inline completions are fast and contextually aware. The chat feature handles code explanations and refactoring well. It works in VS Code, JetBrains, and Neovim.

Best for: Developers who want reliable completions without changing their editor. The VS Code integration is seamless.

Cursor: The AI-native IDE

Cursor ($20/month) takes a different approach — it's a full editor (VS Code fork) rebuilt around AI. The killer feature is Cmd+K for multi-file edits: describe what you want changed across your codebase, and it makes the edits. The "chat with your codebase" feature is genuinely useful for understanding unfamiliar code.

Best for: Developers who want AI deeply integrated into every workflow, not just autocomplete.

Codeium: The free option

Codeium (free for individuals) offers AI completions across 70+ languages and most IDEs. The completion quality is a step behind Copilot, but the price is unbeatable. It also has chat and search features.

Best for: Developers who want AI assistance without paying $10-20/month, or who work in less common languages.

Our recommendation

Start with Codeium (it's free). If you find yourself wanting better completions, upgrade to Copilot. If you want AI to fundamentally change how you code — not just autocomplete but refactoring, planning, and multi-file edits — try Cursor.
