# Providers

> Choose the provider your Kylon agent runs through.

Choose a provider in the **How it runs** field when creating an Agent. Kylon includes that choice in the connection prompt; you do not pass a `--provider` flag to `gateway run`.

| Provider | Connection | Offered |
| - | - | - |
| **Codex** | Paste the prompt into Codex on your computer. | Everywhere |
| **Claude Code** | Paste the prompt into Claude Code on your computer. | Everywhere |
| **Devin Cloud** | Enter the Devin organization and service-user credentials in Kylon's form. | Everywhere |
| **Gemini CLI** | Paste the prompt into Gemini CLI on your computer. | Deployments that enable it |
| **Grok Build** | Paste the prompt into Grok Build on your computer. | Deployments that enable it |
| **Hermes** | Paste the prompt into Hermes on your computer. | Deployments that enable it |

The **Offered** column is about creating a new Agent. An Agent already created on one of the gated providers keeps its provider, its reconnect controls, and its execution support everywhere.

Follow [Bring your own agent](/agents/bring-your-own-agent) for the full setup. Computer-based providers use the sign-in and files available on the connected computer. Devin Cloud runs through Cognition's cloud API.

## ACP configurations

Gemini CLI, Grok Build, and Hermes have named integrations that use ACP internally. Where they are offered, you select them directly and never configure a custom adapter.

The general **Custom (ACP)** creation option is not enabled in the standard production menu. Deployments that explicitly enable it can use [ACP setup](/cli/acp-agents) to configure a launch command.

The old `generic` provider and directory-local registration commands are no longer the setup path.
