Claude Code is Anthropic's agentic CLI coding tool that runs in the terminal and can autonomously navigate codebases, edit files, run commands, and complete complex software engineering tasks. Powered by Claude Opus 4.7 and Sonnet, with usage-based pricing or included on Pro/Max subscriptions.
Pi is a minimal, opinionated terminal-based coding agent created by Mario Zechner, the creator of libGDX. It ships with just four core tools—read, write, edit, and bash—and a system prompt under 1,000 tokens, emphasizing simplicity and extensibility. Pi supports TypeScript extensions and skills for customization, and it powered the OpenClaw project that reached over 145,000 GitHub stars.
