No-code chatbot builder for conversational experiences
Bottender
Declarative framework for building cross-channel conversational experiences
Bottender lets developers create bots for Messenger, LINE, Slack, Telegram, and Viber with declarative actions, native user experience, easy setup, and production-ready features.
Overview
Overview
Bottender is a JavaScript/TypeScript framework that simplifies building conversational user interfaces across major messaging platforms. By letting developers describe actions declaratively for each event and state, the framework produces predictable, easy‑to‑debug code while handling the underlying API intricacies.
The library offers native‑like experiences on Messenger, LINE, Slack, Telegram, and Viber, supporting features such as profile sync, rich menus, interactive messages, and payment flows. A CLI (npx create-bottender-app) scaffolds projects with minimal configuration, automatically managing server listening, webhook registration, and signature verification. Production‑ready optimizations like request batching and extensive channel adapters make it suitable for large‑scale deployments. Community support is available through a Discord server and a growing ecosystem of utilities like bottender-compose.
Developers familiar with Node.js can integrate Bottender into existing TypeScript codebases, leverage its built‑in routing utilities, and extend functionality with custom handlers, enabling rapid iteration from prototype to production.
