## What it is
Bottender is a TypeScript/Node.js framework for building conversational user interfaces (chatbots) across multiple messaging channels including Messenger, LINE, Slack, Telegram, and Viber. It provides a declarative, router-based approach to handling conversation events and states, built on top of the Messaging APIs library.

## Use cases
- build a chatbot for Facebook Messenger
- create a LINE bot in Node.js
- build a multi-channel bot that works on Slack and Telegram
- handle webhook setup and signature verification for messaging platforms
- manage conversation state and routing for a chatbot
- prototype a bot locally in console mode before deploying
- send messages and replies to users on Viber

## When to choose
- you need one codebase serving multiple messaging platforms
- you want a declarative, router-style structure for conversation flows
- you want built-in webhook handling, session, and state management
- you are building production chatbots in Node.js or TypeScript

## When to avoid
- you need an actively developed framework with frequent updates
- you want AI/LLM-driven agents rather than rule-based conversational flows
- you need channels not supported (e.g., WhatsApp, Discord)
- you prefer a low-level SDK for a single messaging platform

## Facets
- artifact type: framework
- maturity: maintenance
- function: chatbot, web-framework, routing, middleware, state-management
- domain: chatbots, messaging-platforms, web-development
- platform: cross-platform
- tags: messenger, line, slack, telegram, viber, conversational-ui, typescript, multi-channel, automation, nodejs, web-server
