Open-Source Autonomous Coding Agents

OpenCode is a free, MIT-licensed AI coding agent for developers working in a terminal, IDE, or desktop app. The desktop app runs on macOS, Windows, and Linux, with support for both Apple Silicon and Intel Macs. It can use local models, giving developers a way to run the model on their own hardware.

Codex CLI is an open source coding assistant that runs on your computer and works with local repositories. It's for developers who want to explore code, make changes, and use their existing development tools from the terminal. It runs on macOS, Windows, and Linux under the Apache 2.0 license.

Cline is an AI coding agent for developers who want help understanding a codebase and changing it. Its shared agent core is open source under Apache 2.0. You can use it in VS Code, JetBrains IDEs, or a terminal. A native desktop app runs on macOS and Windows. No editor is required for desktop sessions. The JetBrains plugin itself is not open source.

Goose is a general-purpose AI agent that runs on your computer. It suits people who want an agent for coding, research, writing, automation, or data analysis, without committing to one model provider. The desktop app runs on macOS, Windows, and Linux; there's also a CLI for terminal work and an API for use in other software.

LLMKube is a free, open-source Kubernetes operator for teams and homelab owners running local LLM inference across their own hardware. It manages Linux GPU servers and Apple Silicon Macs together, so a mixed fleet can serve models through the same platform. It uses the Apache 2.0 license.

GPT Pilot is a self-hosted AI coding assistant for developers who want an agent to build applications under their supervision. The project is no longer maintained. It uses the FSL-1.1-MIT source-available license, with restrictions on competing uses. It runs locally as a Python CLI and is the core technology behind the Pythagora VS Code extension.

gpt-engineer is a locally run coding assistant for developers who want to experiment with AI code generation and build their own agents. It can create software from plain-language descriptions or make requested changes to an existing codebase. The project is archived and no longer maintained. Its Python code is open source under the MIT license.

PearAI is an open source AI code editor built on Microsoft’s VS Code, for developers and makers who want AI assistance inside their project. It combines questions about existing code with an agent that can write features and fix bugs. Its VS Code foundation gives it a familiar editing environment.

Refact is a self-hosted AI coding assistant for developers who want an agent to work across their repository and development tools. The original project is archived and no longer maintained; ongoing development has moved to JegernOUTT/refact. The original code uses the BSD-3-Clause license.

Devika is a self-hosted AI coding agent for developers who want to give a software task in plain language and have an agent plan the work, research it and write code. Modeled after Cognition AI's Devin, it runs on your own machine with a browser interface and supports local LLMs through Ollama. It's open source under the MIT license.

Plandex is an open source, terminal-based AI coding agent for developers working on changes that span many files. Its review sandbox holds generated edits apart from your project files so you can inspect the accumulated changes before applying them. You can run its server locally through Docker or host it on your own server. The code uses the MIT license.

gptme is a self-hosted AI agent that works directly in your terminal, with access to your files and installed tools. It's for developers who want a coding assistant in their own environment, and people who want an agent for data analysis or other knowledge work. The software is free under the MIT license and doesn't require a gptme account.

ChatDev is a self-hosted platform for building teams of AI agents through a visual workflow editor. It's for people who want agents to collaborate on research, data analysis or software projects without writing the orchestration code themselves. You define each agent's role and how information passes between them.

MetaGPT organizes AI agents into a software development team, with roles for product management, architecture, project management and engineering. It's a self-hosted Python framework for developers who want to generate software projects from plain-language requirements or build their own collaborative agents.

Qwen Code is an Apache 2.0 licensed AI coding agent for developers who want help working through a codebase, changing code and checking the result. It runs on macOS, Windows and Linux, with a terminal interface and a desktop app. It builds on Google Gemini CLI and has developed into an agent that can use Qwen models alongside other model providers.

SWE-agent is an open-source AI coding agent that lets a language model use tools to attempt fixes for issues in GitHub repositories. It's aimed at developers and researchers studying how agents handle real software tasks. The project is in maintenance-only mode: mini-swe-agent has superseded it, and the maintainers recommend that successor for new users.

Chatbox is an AI chat client for people who want local models and cloud providers in the same app. It connects to Ollama for local LLM use and supports GPT, Claude, Gemini, Grok and DeepSeek with your own API keys. Chatbox also offers its own hosted model service.

OpenHands is a coding agent platform for developers and teams that want agents to make changes across a codebase and handle recurring engineering work. You can run it on your own computer or self-host it on a server. Its core is open source under the MIT license, and a separate OpenHands Cloud service offers hosted execution.

Kilo Code is an AI coding agent for developers who want help writing and understanding code in their editor or terminal. It runs in VS Code, JetBrains IDEs and the CLI, with cloud agents available for remote work. The project is open source under the MIT license and can be self-hosted.

Code Buddy is an AI coding assistant for developers who want a terminal agent running on their own machine, with a choice of local or cloud models. It reads repositories, edits code and runs commands on Linux, macOS and Windows. Ollama keeps model inference local without an API key or account; cloud providers send model requests off the machine. Routing includes automatic provider failover.
