One of OpenClaw's greatest strengths is that it is not tied to a single chat platform. Whether you prefer Telegram, Discord, or Lark, you can connect an AI assistant through the same OpenClaw instance. This article provides a systematic overview of all chat channels currently supported by OpenClaw, helping you choose the best integration for your use case.
Channel Categories: Native vs Plugin-Based
OpenClaw's channel support falls into two main categories:
- Native Integrations: Maintained by the core team, ready to use out of the box, with the highest levels of stability and feature completeness.
- Plugin-Based Integrations: Developed by the community or third parties, integrated through the plugin system, with potentially varying feature coverage.
There is also a legacy (deprecated) native iMessage channel, for which the BlueBubbles approach is now recommended as a replacement.
Native Integration Channels in Detail
Telegram — The Easiest Starting Point
Telegram is widely recognized as the easiest channel to get started with. It uses the grammY library under the hood and requires only a Bot Token — just create a bot through BotFather and paste the token. It supports both private and group chats, with solid text, image, and file transfer capabilities. If you are using OpenClaw for the first time, Telegram is highly recommended as your starting point.
WhatsApp — Best for Personal Messaging
The WhatsApp integration is built on the Baileys library and connects to your WhatsApp account via QR code pairing. On first launch, OpenClaw prints a QR code in the terminal — scan it with your phone's WhatsApp to complete the binding. Note that this approach uses the WhatsApp Web protocol rather than the official Business API, so there is some account ban risk. It is recommended to use a secondary account rather than your primary one.
Discord — Ideal for Communities and Teams
Discord connects through the Bot API, supporting both server channel messages and direct messages (DMs). You need to create an application in the Discord Developer Portal, generate a Bot Token, and invite the bot to your target server. Discord is especially well-suited for gaming communities, development teams, and other groups that already have a Discord server.
Slack — Enterprise Workspace Integration
The Slack integration is built with the official Bolt SDK, supporting channel messages, threaded replies, and direct messages. Configuration is a bit more involved, requiring you to create an app in the Slack API dashboard and set up OAuth permissions. But once configured, the experience within an enterprise workspace is excellent.
Signal — The Privacy-Focused Choice
The Signal integration relies on the signal-cli tool, and setup involves more steps, including registering a Signal account with a dedicated phone number. But if privacy is a top priority, Signal's end-to-end encryption is something other platforms cannot match.
BlueBubbles (iMessage) — Apple Ecosystem Access
BlueBubbles is currently the recommended approach for connecting to iMessage, replacing the earlier deprecated native iMessage integration. It requires a macOS device to serve as a relay server. The setup threshold is higher, but for dedicated Apple ecosystem users, it is worth the effort.
Google Chat — For Google Workspace Users
Designed for teams using Google Workspace, it connects through the Google Chat API. Service account configuration in the Google Cloud Console is required.
WebChat — Web Embedding Solution
WebChat provides an embeddable chat widget for web pages, allowing you to offer an AI conversation interface directly on your website without requiring users to install any app.
Plugin-Based Channels
| Channel | Use Case | Notes |
|---|---|---|
| Lark | Enterprise workflows in China | Requires Lark Open Platform app configuration |
| LINE | Users in Japan/Southeast Asia | Via LINE Messaging API |
| Matrix | Self-hosted open-source communities | Decentralized protocol, privacy-friendly |
| Mattermost | Self-hosted Slack alternative | Open-source team collaboration platform |
| Microsoft Teams | Microsoft ecosystem enterprises | Configuration process is more complex |
| Nextcloud Talk | Nextcloud users | Self-hosted communication solution |
| Nostr | Decentralized social | Emerging protocol, community-driven |
| Tlon | Urbit ecosystem | Niche but with a unique community |
| Twitch (IRC) | Livestream interaction | IRC-based, suitable for stream chat bots |
| Zalo | Vietnamese users | Dominant messaging app in Vietnam |
Plugin-based integration stability and feature coverage depend on each plugin's maintenance status. Before using one, it is recommended to check the corresponding plugin's GitHub repository for the latest information.
Feature Comparison Overview
| Feature | Telegram | Discord | Slack | Signal | WebChat | |
|---|---|---|---|---|---|---|
| Setup Difficulty | Low | Medium | Medium | Medium-High | High | Low |
| Text Messages | Supported | Supported | Supported | Supported | Supported | Supported |
| Image Support | Supported | Supported | Supported | Supported | Supported | Supported |
| File Transfer | Supported | Supported | Supported | Supported | Partial | Partial |
| Emoji/Reactions | Full | Full | Full | Full | Basic | Basic |
| Group Chat | Supported | Supported | Supported | Supported | Supported | N/A |
| PM Pairing | Supported | Supported | Supported | Supported | Supported | N/A |
All channels support basic text messages, but media file and emoji support varies by platform. Group chat behavior also differs across channels — for example, some channels require @mentioning the bot before it will respond.
Multi-Channel Operation and Security
OpenClaw supports running multiple channels simultaneously. You can enable a combination of Telegram + Discord + WhatsApp in the configuration file, and OpenClaw will automatically route messages to the correct channel based on the session. Conversation contexts are independent across channels and will not cross over.
On the security front, OpenClaw provides two key mechanisms:
- Private Message Pairing: Users must enter a pairing code when first messaging the bot privately, preventing strangers from freely using your AI quota.
- Allowlists: You can restrict interactions to specific users or groups only.
Both features work across all channels, ensuring your AI assistant is not abused.
How to Choose?
- Personal exploration: Start with Telegram — you can be up and running in 5 minutes.
- Daily messaging: WhatsApp or Signal, depending on your privacy preferences.
- Team collaboration: Slack (international teams) or Lark (teams in China).
- Community management: Discord or Matrix.
- Website integration: WebChat.
There is no need to agonize over the choice — OpenClaw's multi-channel architecture lets you add new channels at any time. All channels share the same AI configuration and skills, making the switching cost virtually zero.
