  • Landing pages

The agent is built in.

OpenGUI is not a window on top of another tool. It does not run any of these behind the scenes:

  • Claude Code
  • OpenCode
  • Codex CLI
  • Pi

Its own Harness does the work, saves every session's history, and uses exactly four tools in the folder you choose.

read

Opens your files and uses what's in them as context for the job.

write

Creates new files: drafts, scripts, pages, slides, or plans.

edit

Changes one exact part of a file and leaves the rest alone.

shell

Runs non-interactive commands in the project folder, like builds and checks.

Set up once.
Three steps, all in the app.

1

Install OpenGUI

Pick the installer for macOS, Windows, or Linux and open the app. It's free and open source.

2

Connect your model

Add the base URL, API key, and model name for any OpenAI-compatible endpoint. That's the one thing OpenGUI needs from you.

3

Choose a folder

Start a session, describe the job, and watch each tool call and result as OpenGUI works.

Start at your desk. Pick it up on your phone.

Connect the desktop app, a browser, or your phone to the same OpenGUI Host and the same Sessions are waiting, with transcripts, model choice, and queued prompts included. On its own, the desktop app runs a Local Host on your computer.
