Open-Source Computer-Use and Browser Agents

Phone Harness connects an AI agent to a real iPhone or Android so it can use apps through their screens. It's for developers who want Claude Code, Codex, or another agent to carry out phone tasks without a dedicated app API. The software is open source under the MIT license, and it doesn't require a jailbreak or an app installed on the phone.

LM Studio is a desktop application for downloading and running language models on macOS, Windows and Linux. You can search for models, manage downloads and chat with them through the app. Downloaded models can run offline, including document chat that uses files on your computer.

Cua gives AI agents access to computers they can inspect and operate, with tools for desktop automation, local virtual machines, and hosted fleets. It's for developers building agents that work across native apps and browsers, or evaluating how well those agents complete computer tasks. You bring the agent and model.

Browser Use is an MIT licensed browser agent for developers who want AI to carry out tasks on websites. You can run the open source agent on your own machine from Python, choose a model, and use either a local or cloud browser. A CLI is available for browser tasks too.

agent-browser gives AI agents a compact text view of a browser page, with references that identify the exact elements they can interact with. It's for developers who want coding assistants or other agents to use websites without filling their context with a full page's HTML. The open source tool runs locally on macOS, Linux and Windows under the Apache 2.0 license.

OpenAgent is a self-hosted personal AI assistant that combines document search with agents that can act on your behalf. It's for people who want an assistant on their own computer or server, and teams building agents around their documents and workflows. It runs natively on Windows, macOS and Linux as a single executable. It's free and open source under Apache 2.0.

Self-Operating Computer lets a vision-capable AI model control a desktop by reading the screen and choosing mouse and keyboard actions to carry out a goal. It's a Python framework for developers and researchers exploring AI agents that work through application interfaces. The code uses the MIT license.

LaVague is a Python framework for developers building AI agents that carry out tasks in a web browser. An agent takes a plain-language objective, examines the current page, and generates and executes browser actions across multiple steps. It's open source under the Apache 2.0 license.

Kerlig is a paid AI writing assistant for Mac that works with text in the apps you already use. It's aimed at people writing client emails, Slack replies and Jira tickets who want help editing and drafting without moving everything into a browser chat. It runs on Apple Silicon and Intel Macs with macOS 12 or later.

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.

Enconvo is a native AI assistant and agent for Mac that can use your screen and selected text as context, then work inside your apps. It's for people who want help with writing, research and everyday tasks alongside the app they're using. A sidebar keeps the agent beside the current app, while text selection tools give quick access to editing and translation.

Open Interpreter is a terminal coding assistant built around open-weight models, with model-specific behavior for Kimi, Qwen and DeepSeek. It's a fork of OpenAI's Codex for developers who want to choose their model provider while keeping a familiar agent interface. The project uses the Apache 2.0 license.

Chrome DevTools MCP gives AI coding assistants access to a live Chrome browser through a locally running MCP server. It's for developers who want their agent to inspect how a web app behaves, investigate errors and measure performance alongside its coding work. It works with clients such as Claude Code, Cursor, Copilot and Antigravity.

Nanobrowser is an open-source AI agent that automates web tasks inside Chrome or Edge. It's for people who want to delegate repetitive browsing or research while choosing which models handle the work. The extension runs in your browser and is an alternative to OpenAI Operator, with an Apache 2.0 license.

Leon is a self-hosted personal AI assistant for Linux, macOS and Windows. The project focuses on the 2.0 Developer Preview on its develop branch. Its MIT-licensed runtime combines tools, context and memory with a local web interface.

OpenAdapt turns a demonstrated task into a repeatable program for browser, desktop, and remote applications. Its local, MIT-licensed open-source engine is for teams and AI agent builders who need to automate work in interfaces their APIs can't reach. It checks the outcome independently before reporting success and stops when verification fails.

Agent S is an open-source AI agent framework that controls ordinary desktop and web applications through the screen, mouse and keyboard. It runs on macOS, Windows and Linux and is aimed at developers, computer-use researchers and people building automation for their own desktops. You describe the task in natural language; the agent clicks, types and scrolls without requiring an API integration or a separate script for each application.

Skyvern uses vision models to carry out tasks in a browser, such as filling forms, collecting data, and working through logins. It's for teams automating websites whose layouts change, as well as developers who want AI actions alongside Playwright. Instead of depending on fixed page selectors, it identifies visible elements and decides how to interact with them.

Stagehand is an open-source browser automation SDK for developers building AI agents that interact with websites and extract structured data. It can run with Chrome on your own machine or use Browserbase's cloud browsers. Local runs require Chrome. The project uses the MIT license and supports TypeScript, Python, and Go.

UI-TARS Desktop is an open-source AI agent that controls computer interfaces through natural language requests. It runs on Windows and macOS and supports browser use, with operators for both local and remote computers. It's for people who want an agent to carry out tasks in existing apps, such as changing a VS Code setting or checking an issue on GitHub.

Playwright MCP lets AI agents control a browser by reading structured page information rather than interpreting screenshots. It's for developers building browser automation, exploratory tests or agent workflows that need to keep a browser session open across repeated actions. The server runs locally on macOS, Windows and Linux, or as a self-hosted service.

Agenta is an MIT-licensed, open source workspace for teams that want AI agents to handle tasks in chat and continue recurring work in the background. You can self-host it with Docker Compose or Helm to keep agents and workspace data on your infrastructure, or use Agenta Cloud as a hosted service.

Steel is a browser API for developers building AI agents that interact with websites. It runs Chrome sessions locally or on a self-hosted server through Docker, so you can keep browser infrastructure on hardware you control. The code uses the Apache 2.0 license. Steel also offers a hosted service where browser sessions run in its cloud.

PocketPaw is a self-hosted AI agent for people who want a personal assistant that can work with files, write code and use a browser on their own computer or server. It runs on macOS, Windows and Linux, with a web dashboard and access through messaging apps. It is open source under the MIT license.
