The English and Japanese guide/features pages led their platform enumerations with China-only platforms (WeChat, WeCom, DingTalk), and the "AI customer service" example named China-only platforms to a global / Japanese audience. Reorder the marketing enumerations and examples so each locale leads with the platforms mainstream in its region: - en: Discord, Telegram, Slack first, then QQ/WeChat/WeCom/Lark/DingTalk - ja: LINE, Slack, Discord, Telegram first, then the China platforms Only the hero/landing prose and the use-case examples are reordered; the functional webhook/adapter reference lists are left as-is. The Chinese docs already lead with China platforms and are unchanged. No platform is added that LangBot does not actually support.

## Core Capabilities at a Glance
|
|
|
|
- **AI Conversation & Agent** — multi-turn dialogue, tool calling (function calling), multimodal (image/audio/file) and streaming output, ready out of the box.
|
|
- **RAG Knowledge Base** — a built-in knowledge-base engine (vector retrieval + Rerank re-scoring) so your bot answers from your private knowledge, extensible via plugins to seamlessly connect external knowledge-base services like RAGFlow, Dify and FastGPT.
|
|
- **All-Platform Coverage** — one codebase reaches Discord, Telegram, Slack, LINE, KOOK, Matrix, QQ, WeChat, WeCom, Lark, DingTalk and more.
|
|
- **Deep Agent Platform Integration** — native connectors for Dify, Coze, n8n, Langflow, Deerflow, Aliyun Bailian, Ant TBox and other orchestration & workflow platforms.
|
|
- **Skills & Code Sandbox** — on-demand instruction packs paired with a securely isolated code-execution sandbox, so the agent actually *gets things done*.
|
|
- **MCP Protocol** — acts as a client into the Model Context Protocol tool ecosystem, supporting both Stdio and HTTP transports.
|
|
- **Web Management Panel** — configure, manage and monitor bots visually in the browser, no manual config editing.
|
|
- **Production-grade Plugin System** — hundreds of community plugins on a cross-process, event-driven architecture that's safe and hot-pluggable.
|
|
- **Multi-pipeline Architecture** — run multiple pipelines per instance so different bots serve different scenarios, with access control, rate limiting, sensitive-word filtering and comprehensive monitoring.

## LLM Application Paradigm Implementation
|
|
|
|
LangBot turns mainstream LLM application paradigms into out-of-the-box capabilities, covering the full path from "can chat" to "can get work done."
|
|
|
|
| Paradigm | Status | Notes |
|
|
| --- | --- | --- |
|
|
| Agent | ✅ | Built-in agent with tool calling, multi-turn reasoning, multimodal and streaming output |
|
|
| RAG (Knowledge Base) | ✅ | Built-in knowledge-base engine (default Chroma vector store + Rerank re-scoring), pluggable into external knowledge bases like RAGFlow, Dify and FastGPT |
|
|
| MCP | ✅ | Acts as an MCP client into the tool ecosystem; supports Stdio and HTTP |
|
|
| Skills | ✅ | On-demand instruction packs, pulled into context only when matched — zero extra overhead |
|
|
| Code Sandbox | ✅ | Securely isolated code-execution environment with Docker / nsjail / E2B backends |
|
|
|
|
- **Skills**: package a professional workflow, template or script into an on-demand instruction pack — the agent pulls it into context only when the user's request matches, keeping the System Prompt clean. See the [Skills doc](/en/usage/skills/readme).
|
|
- **Code Sandbox**: gives the agent securely isolated code-execution capability, automatically picking the best of the Docker / nsjail / E2B backends — the runtime foundation for Skills and native tools. See the [Sandbox doc](/en/usage/sandbox/readme).
|
|
|
|
## System Extensibility
|
|
|
|
LangBot offers a complete extension surface for secondary development and enterprise integration.
|
|
|
|
- **HTTP Service API**: access LangBot's entities through HTTP interfaces with API-key authentication, for easy integration with existing systems.
|
|
- **Outgoing Webhook**: push LangBot's internal events to external systems in real time, enabling event-driven automation.
|
|
- **Production-grade Plugin System**: built on cross-process communication and async technology, supporting various component extensions — safe, stable and hot-pluggable; hundreds of community plugins install in one click from the [extension marketplace](https://space.langbot.app).
|
|
- **Web Management Panel**: do all your bot, model, pipeline, knowledge-base and plugin configuration and monitoring visually.
|
|
|
|
## Deployment Options
|
|
|
|
LangBot supports everything from a one-line command to a Kubernetes cluster:
|
|
|
|
- **LangBot Cloud (recommended)**: [a hosted, deploy-free, out-of-the-box version](https://space.langbot.app/cloud).
|
|
- **One-line start**: `uvx langbot`, then open `http://localhost:5300`.
|
|
- **Docker Compose**, **aaPanel**, **Kubernetes**, **one-click cloud deploy on Zeabur / Railway**, and more.
|
|
|
|
See the [deployment docs](/en/deploy/langbot/kubernetes) and [quick start](/en/insight/guide).
