Claude Code
✓ VerifiedAnthropic's terminal-based AI coding agent with 80.9% SWE-bench, Agent Teams, and GitHub Actions
Our Review
Claude Code is Anthropic's terminal-first coding experience, available in Claude desktop, web, and CLI. It now centers on the 4.6 generation (Sonnet 4.6 for broad use and Opus 4.6 for deeper reasoning tiers), with code search, multi-file edits, and permissioned command execution. The large context window and project context via CLAUDE.md make it well-suited for larger codebases.
We tested Claude Code in terminal workflows: exploring a new repo, refactoring across several files, and running tests. The permission model is clear: you approve or reject each command, and diffs are shown before applying. This feels safer than fully autonomous agents when working in production code. The experience is polished and integrated with Anthropic's broader product line.
Access is included with Claude Pro, Max, Team, and Enterprise; API usage is billed per model. If you already pay for a Claude plan and prefer a terminal-first workflow, Claude Code is a strong option. It is Anthropic-only (no third-party models), so if you need flexibility across providers, consider Aider or Continue instead.
