OpenGUI

OpenGUI is a desktop and web coding agent built on the first-party OpenGUI Host and Harness. The Host owns projects, model connections, Sessions, durable transcript history, and execution. The Harness exposes four workspace tools: read, write, edit, and shell.

Requirements

• Node.js 22.19 or newer (release CI uses Node.js 24)
• pnpm 11.18.0
• An OpenAI-compatible model endpoint and API key

See docs/model-compatibility.md for the exact custom endpoint contract and docs/operations.md for security, backup, recovery, and troubleshooting guidance.

No external coding-agent CLI or SDK is required.
