Open Interpreter

Open Interpreter started in 2023 as the natural-language interface that let LLMs run Python, JavaScript, and shell code on your machine, and its current incarnation doubles down on that idea as a Rust-based terminal coding agent forked from OpenAI's Codex CLI and optimized for low-cost models such as Kimi K3, DeepSeek, and Qwen. Commands execute inside native sandboxing on macOS, Linux, and Windows, models switch at runtime with the /model command, and the harness behavior itself is inspectable via /harness. It reads shared AGENTS.md instruction files and .agents/skills directories, supports MCP, hooks, and granular permissions, integrates with editors through the Agent Client Protocol, and ships a built-in QA skill for testing web and native apps. Installation is a one-line shell or PowerShell script from openinterpreter.com, after which the agent launches with the i or interpreter command; the original Python project is maintained separately. The code is Apache-2.0, and at roughly 67.4k stars it remains one of the most popular local agent tools to come out of the 2023 wave.
