Pi Agent vs Claude Code After 100 Hours of Real Use

Pi, a minimal open-source coding agent with just four tools, outperformed Claude Code on a real agentic benchmark — 20/30 tasks passed versus 16/30 — at one-fifth the cost. Built by libGDX creator Mario Zechner as a direct rejection of Claude Code's complexity, Pi supports 300+ models and MIT-licensed extensibility. Yet despite the scorecard favoring Pi, most developers still use Claude Code daily for its guardrails and subscription pricing.
