AI code assistants have gone from novelty to necessity. Developers using AI coding tools ship 40-55% faster according to GitHub research. Here is how the top three tools stack up.
GitHub Copilot
GitHub Copilot is the market leader by adoption. Powered by GPT-4, it integrates natively into VS Code, JetBrains, Vim, and Neovim. Copilot Chat adds a full conversational interface for explaining code, fixing bugs, and writing tests.
Price: $10/month individual | $19/month business
Cursor
Cursor is a VS Code fork that puts AI at the centre of the editor. Its Composer feature lets you describe a multi-file change in plain English and applies it across your entire codebase in one shot.
Price: Free (limited) | $20/month Pro
Tabnine
Tabnine differentiates on privacy. It offers a local model option that runs entirely on your machine - zero code ever leaves your environment. The go-to choice for enterprises handling sensitive code.
Price: Free (limited) | $12/month Pro
Recommendation
- Most developers: Start with Cursor - free tier is generous, multi-file edits are significant
- JetBrains users: GitHub Copilot (Cursor is VS Code only)
- Enterprise/privacy: Tabnine with local model
