LangBot vs Botpress

Compare LangBot, an open-source AI bot platform you can self-host, with Botpress Cloud, a hosted bot builder: deployment, channels, Chinese IM support, AI back ends and licensing.

Last reviewed:

In short

Botpress Cloud is a hosted bot builder with a visual studio and a hub of integrations. LangBot is open source and self-hostable (or managed through LangBot Cloud), connects to Chinese and global chat apps, and can use Dify, n8n, Coze or Langflow apps as the bot's brain as well as its built-in Agent.

  • Control your bots in natural language

    Say what should change. Agents and the assistant carry it out after you approve.

    In the support group, only answer when someone @mentions the bot, and welcome new members.
    Routing: reply on @mention
    group.member_joined → welcome
    Applied after you confirm
    Details ›

    Agents, a unified API and standard platform events and APIs work together. Every Workspace operation (bots, routing, pipelines, models, knowledge bases, monitoring) is one catalog shared by the HTTP API, the MCP server, the Workspace Assistant and plugins, and adapters expose standard platform APIs such as send, reply, edit and recall messages, query groups and members, and, where the platform allows, mute or remove members. So you can change how a bot behaves by telling the Workspace Assistant, or let an authorized agent act on the platform from a chat instruction. Writes need your confirmation or an explicit permission grant.

  • Workspace Assistant

    Describe the goal; review the proposed changes; confirm.
