# Interfaces

> Connect deployed agents to Slack, Discord, WhatsApp, Telegram, and protocols like A2A and AG-UI.

You've deployed your platform and added agents. Now connect them to where your users already are.

Interfaces let users interact with your agents through Slack, Telegram, WhatsApp, Discord, or your own frontend. Each interface handles user isolation, message threading, streaming, and platform-native formatting so you focus on the agent, not the plumbing.

## Choose an Interface

| Interface                                        | Best For                           | Setup Time |
| ------------------------------------------------ | ---------------------------------- | ---------- |
| [Slack](/deploy/interfaces/slack/overview)       | Teams already on Slack             | 15 min     |
| [Telegram](/deploy/interfaces/telegram/overview) | Public bots, quick prototypes      | 5 min      |
| [WhatsApp](/deploy/interfaces/whatsapp/overview) | Customer messaging at scale        | 30 min     |
| [Discord](/deploy/interfaces/discord/overview)   | Gaming communities, public servers | 10 min     |
| [AG-UI](/deploy/interfaces/ag-ui/overview)       | Custom web/mobile frontends        | Varies     |
| [A2A](/deploy/interfaces/a2a/overview)           | Agent-to-agent communication       | 10 min     |

## Prerequisites

Before connecting an interface:

1. **Running AgentOS** — [Docker](/deploy/templates/docker/deploy), [Railway](/deploy/templates/railway/deploy), or [AWS](/deploy/templates/aws/deploy)
2. **Public URL** — Your AgentOS must be reachable from the internet
3. **Platform credentials** — Bot tokens, API keys, or OAuth apps (see each interface guide)

<Tip>
  For local dev, expose localhost with [ngrok](https://ngrok.com), [Cloudflare Tunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/), or [localhost.run](https://localhost.run).
