Transform hours of debugging into seconds with a single command. Experience coding at thought-speed with Claude's AI that understands your entire codebase—no more context switching, just breakthrough results.
Claude Code is Anthropic’s agentic coding assistant that embeds the Claude Opus 4 model straight into a developer’s terminal and IDE. It deeply understands large codebases, makes coordinated changes across multiple files, runs shell commands and tests, and surfaces proposed edits for review—all triggered with natural-language prompts.
First released as a research preview on 24 Feb 2025 alongside Claude 3.7 Sonnet, the tool reached general availability on 22 May 2025 with integrations for VS Code, JetBrains IDEs and GitHub Actions. An extensible SDK now lets teams build custom automations on the same core agent. By combining a million-token context window with code-specific optimizations, Claude Code delivers pair-programming-level support while keeping engineers in full control of their workflow.
