WhatsApp vs Telegram for Your AI Assistant
Both are free to use with OpenClaw — but they work in fundamentally different ways. Telegram uses an official bot API. WhatsApp connects via WhatsApp Web. Here's what that means in practice.
📌 Important context: OpenClaw's WhatsApp integration uses WhatsApp Web (via the Baileys library) — the same mechanism as scanning a QR code in your browser. This is not the WhatsApp Business API. There are no per-message fees, no Meta business account required, and no approval process.
How each channel actually works
Telegram has a fully official, documented Bot API that's been free since 2015. You create a bot with BotFather, get an API token, and connect it to OpenClaw. No special approval, no usage fees, no rate limits for personal bots. Telegram has committed publicly to keeping the Bot API free.
WhatsApp in OpenClaw works differently. You link a phone number by scanning a QR code — exactly like WhatsApp Web in a browser. OpenClaw then runs as that phone's WhatsApp session on your server. It's a headless browser session, not an API integration. This means it's free and works with any regular WhatsApp number, but it also means Meta doesn't officially support this use case.

Stability considerations
Because OpenClaw's WhatsApp uses WhatsApp Web under the hood, it's dependent on Meta's WhatsApp Web protocol remaining consistent. The Baileys library (which OpenClaw uses) is actively maintained and widely used, but there's no official guarantee of stability. Telegram's Bot API, by contrast, has remained backward-compatible since 2015 — breaking changes don't happen.
For a personal AI setup where occasional reconnection is acceptable, WhatsApp works fine. For something that needs to run without maintenance for months, Telegram is more reliable.
Our recommendation
Use Telegram as your primary channel. It's free, stable, officially supported, and has better features for running multiple AI agents (Group Topics is genuinely excellent for this). The Group Topics feature lets you have one Telegram group with separate sections for Prospects, Security Alerts, Job Leads, and Direct Chat — essentially a free Slack alternative for your AI infrastructure.
Use WhatsApp if you need to be reachable by people who won't install Telegram, or if it's genuinely where your life happens. Both work. Telegram is the better tool for the job.
💡 Running both: OpenClaw supports multiple channels simultaneously. You can have Telegram for your main AI workspace and WhatsApp for receiving messages from contacts who only use WhatsApp — all routing to the same assistant.
