Koishi
Cross-Platform Chatbot Framework with Rich Plugin Ecosystem
TypeScript-based chatbot framework supporting QQ, Telegram, Discord, and more. Features a web console, 1000+ plugins, and hot-reload for seamless development.
Overview
Build Powerful Chatbots Across Any Platform
Koishi is a high-performance, extensible chatbot framework designed for both non-technical users and professional developers. Named after the Touhou Project character Komeiji Koishi, it embodies the theme of automated, thoughtful interactions.
No-Code to Pro-Code Flexibility
The built-in web console lets anyone deploy a chatbot in minutes without programming knowledge. Browse and install from 1000+ official and community plugins covering platform adapters, databases, storage, monitoring, and business logic. Connect to QQ, Telegram, Discord, Feishu, and other major chat platforms with multi-account and cross-platform data synchronization. Monitor status, control behavior, and even chat directly through the dashboard.
Developer-First Architecture
Built entirely in TypeScript, Koishi delivers top-tier type safety and IntelliSense that reduces the need for documentation lookups. Core functionality is backed by comprehensive unit tests, establishing best practices for plugin testing and debugging. Hot module reloading enables save-and-refresh workflows comparable to modern frontend development, eliminating constant restarts during plugin development.
After four years of iteration, Koishi provides robust infrastructure for both large-scale interactive applications and lightweight utility bots, supported by detailed documentation and an active community.
