Claw Code is an open-source terminal-based AI coding assistant developed by Ultraworkers. Built on a hybrid architecture featuring a high-performance Rust core (rusty-claude-cli) and Python integration layers, it provides developers with a self-hosted, terminal-native environment for autonomous software engineering tasks. In daily use, Claw Code operates directly inside the developer workspace via an interactive command-line interface. It executes an agentic turn loop capable of inspecting file systems, running workspace commands, executing tests, and applying multi-file code diffs while preserving context across turns through dedicated session stores. What distinguishes Claw Code is its dual-engine performance architecture, integrated slash-command routing, plugin system, and structured agent context modeling via hierarchical AGENTS.md documentation. This gives developers granular control over session persistence and command execution without relying on proprietary, closed-source agent wrappers. Claw Code is available as an open-source project on GitHub under standard community licensing, allowing developers to bring their own API configurations and run the agent locally without proprietary vendor lock-in.
