Claw Code: Open-Source AI Coding Agent Framework Launches with 72K Stars on Day One

GitHub·high signal

Claw Code, built in Python and Rust, publicly launched April 2, 2026 as a clean-room rewrite of Claude Code's leaked agent harness architecture. Within days of going public, the repository surpassed 72,000 GitHub stars and 72,600 forks, making it one of the fastest-growing OSS repos in the AI tooling category. Addresses the gap where LLM-to-tool control layers have remained proprietary — gives developers a fully open, inspectable harness they can study and extend.
