Overview

What is LangBot?

LangBot is an open-source AI bot project focused on production-grade platform for building agentic im bots across discord, slack, telegram, line, wechat, feishu, dingtalk, and more.

Lives in existing communication channels

LangBot brings AI assistance into messaging surfaces rather than forcing users into a separate app.

Bots become useful when they meet users where coordination already happens.

Self-hostable source path

The public repository lets teams inspect runtime behavior, credentials handling, and integration choices before deployment.

AI bots can see sensitive conversations, so source review and controlled hosting matter.

Good comparison target for agent gateways

The project shows how open bots connect LLMs, permissions, plugins, memory, or channel adapters.

These patterns are likely to become a core part of practical open-agent infrastructure.
