Best for autonomous, feature-sized work by terminal-comfortable developers
Claude Code is the most autonomous mainstream option: a terminal-first agent that reads a codebase, plans, edits across many files, runs tests and iterates. It rewards developers who write precise instructions and frustrates those who want autocomplete.
Best for organisations standardising across mixed editors and toolchains
Copilot created this category and remains the safest institutional purchase: it works in every major editor, integrates with GitHub natively, and its enterprise controls are the most mature. Raw agentic capability now trails the newer specialists.
Best free tier and the cheapest credible paid AI editor
Windsurf sits between autocomplete and full autonomy, with a strong free tier that makes it the usual first taste of the category. Capable and well-priced, though it has lost ground to Cursor since its ownership upheaval in 2025.
