Choose the local endpoint
Docker stays on this computer. Relmio checks it without changing any running containers.
Looking for Docker Engine and Compose.
Native Windows is not supported because this feature requires POSIX owner-only file permissions for local credentials.

Relmio will
- Build one target-specific Docker image.
- Bind the selected port exactly to
127.0.0.1. - Generate a separate one-time client credential.
- Keep provider credentials in private Docker volumes.
Relmio will not
- Publish the endpoint to your LAN or internet.
- Turn ChatGPT credentials into Platform API credentials.
- Modify or restart your n8n container.
- Reuse the existing Hostinger deployment.
Install the local container
Enter the OpenAI Platform API key that this endpoint will use upstream. It is sent only to this local Relmio process.
Anyone holding the generated client credential can control Codex inside its isolated container, act through your signed-in ChatGPT session, and may be able to recover that container's ChatGPT session credential. Treat this capability like your ChatGPT password and give it only to a trusted native local app.
Local endpoint is ready
Copy the client settings into your local app.
Relmio shows the generated client credential only in this install response. It cannot recover it after you leave this page.
Relmio shows the replacement first, then activates and verifies it. After successful activation, the previous credential no longer works. Copy the replacement before leaving this page.

Sign the container in to ChatGPT
Relmio starts the official Codex device-code flow. The ChatGPT credential stays in the isolated Codex Docker volume and is not an OpenAI Platform API key.
Open the official OpenAI page and enter this one-time code:

Local-only tester
Test this local Chat Adapter
Relmio sends this browser only to its same-origin local wizard. The wizard then calls the literal loopback adapter address.
Secure the local client credential to begin.
