Botpress

Botpress is an open-source chatbot platform that’s handled over 1 billion messages and supports more than 500,000 developers. It offers a drag-and-drop interface for designing conversation flows and includes a JavaScript IDE for building custom integrations. This makes it suitable for both simple and more advanced setups.

The platform works with popular channels like Facebook Messenger, Instagram, WhatsApp, Microsoft Teams, SMS (via Twilio), web chat, Line, and Viber. If you’re planning to use Instagram, you’ll need a Meta developer app, a Facebook page, and an Instagram Professional account. Business verification, which typically takes 3–5 days, is also required to enable automated, real-time interactions.

Here’s a breakdown of Botpress plans:

Plan Monthly Cost Key Features
Pay-as-you-go Free to start Visual builder, AI credit, API access
Plus $79 Live agent handoff, removal of branding
Team $445 Real-time collaboration, enhanced knowledge bases
Enterprise Custom Custom workspace limits, dedicated support

Each plan includes $5 in monthly AI credit, with spending caps based on the tier. For instance, the Pay-as-you-go plan limits AI usage to $100/month, while the Team plan increases this to $500/month.

Botpress offers technical features like intent classification, entity extraction, custom message widgets (using React and CSS), role-based access control, and an API/SDK for extending its capabilities.

3. Botkit

Botkit

Botkit is a developer-focused tool designed for building chatbots. It belongs to the Microsoft Bot Framework ecosystem and offers a range of features for creating custom bots that work across various messaging platforms.

Botkit’s structure revolves around three main components:

  • Core Library: Handles API calls and session management.
  • Visual Builder: Includes a drag-and-drop interface for designing bots.
  • Platform Adapters: Connects to messaging services for multi-channel deployment.

This multi-channel capability allows chatbots to operate on platforms like Facebook Messenger, Slack, Webex, Twilio SMS, and Google Hangouts using official adapters.

For developers, Botkit offers a middleware system that simplifies message processing through commands like hears(), ask(), and reply(). While it uses Microsoft’s Language Understanding (LUIS) as the default engine for natural language processing, developers can integrate other NLU engines if preferred. The toolkit also includes features like a Yeoman generator for quick project setup, pre-built middleware, event handlers, and authentication management.

Botkit is MIT-licensed, giving developers full control over chatbot functionality and hosting. Plus, its integration with the Microsoft Bot Framework Service ensures consistent conversation management across all supported channels.
