About GitHub
Open Interpreter is an open-source coding agent that emulates the harness from OpenAI's Codex, optimized for low-cost AI models. It runs as a terminal-based tool (command interpreter) and supports multiple model harnesses (native, claude-code, kimi-code, etc.), allowing users to switch providers and models on the fly. The agent executes commands inside native sandboxing on macOS, Linux, and Windows, and includes a built-in QA skill for testing web and native applications via browser automation or the trycua tool. It is ACP (Agent Client Protocol) compatible and can be used as a drop-in replacement for the Codex SDK, enabling integration with ACP-compatible editors and clients.
Key Features
Runs commands inside native sandboxing on macOS, Linux, and Windows
Switches providers and models from the TUI using /model
Inspects or switches Rust-native model harnesses with /harness
Tests web and native apps through built-in QA skill
Runs as an Agent Client Protocol (ACP) agent for editors
ACP compatible and Codex compatible (one-line binary override)
Installation via curl (macOS/Linux) or PowerShell (Windows)
Supports multiple harnesses: native, claude-code, kimi-code, zcode, deepseek-tui, swe-agent, minimal
