Get help with the work in your folders.

OpenGUI can read files, make changes, and run tools inside a folder you choose. Use it for longer jobs without installing Git or a separate coding-agent app.

Free and open source. Available for macOS, Windows, and Linux.

Use it for the work already on your computer.

The agent is built into OpenGUI.

OpenGUI does not run Claude Code, OpenCode, Codex CLI, or Pi behind the scenes. Its own Harness does the work, saves session history, and provides four tools: read, write, edit, and shell.

No extra app

You do not need Git or a separate coding agent.

Your model

Connect an OpenAI-compatible model, then choose a folder.

Saved sessions

OpenGUI keeps your transcript and queued follow-up prompts together.

Set up OpenGUI in three steps.

You can do the whole setup in the app.

  1. 1

    Install OpenGUI

    Pick the installer for macOS, Windows, or Linux and open the app.

  2. 2

    Connect your model

    Add the base URL, API key, and model name for an OpenAI-compatible endpoint.

  3. 3

    Choose a folder

    Start a session, describe the job, and review OpenGUI's tool calls and results as it works.

Continue the same session on another device.

OpenGUI keeps each project's sessions, transcripts, model choice, and queued prompts together. Connect to the same OpenGUI Host to continue from the desktop app, a browser, or mobile.

What OpenGUI can do in a folder.

OpenGUI can inspect and change project files instead of stopping at instructions.

Read
Open files and use their contents as context for the job.
Write
Create files such as drafts, scripts, pages, or plans.
Edit
Change a specific part of a file without replacing the rest.
Shell
Run non-interactive commands in the chosen project folder.

Try OpenGUI on your next project.

Install the app, connect your model, and choose the folder you want to work on.
