Self-hosted Flask chatbot in Python

This page presents the Flask Chatbot product by Palks Studio, a self-hosted conversational template designed to remain understandable, controlled, and usable in real-world projects.

This product provides a Flask-based chatbot designed as a real, production-ready technical architecture, rather than a simple demonstration example.

It is intended for projects looking to integrate a self-hosted conversational assistant, fully controlled in its behavior and adaptable to concrete use cases.

Flask chatbot template in Python, self-hosted, designed for simple integration and full control over system behavior.

The chatbot provides a complete architecture designed for immediate use or integration into an existing project, without requiring external services.

Multiple operating modes are available in order to adapt the behavior to different usage contexts:

• Local mode Responses based on a JSON knowledge base
• External AI mode Optional activation via API key
• Strict mode Responses limited to internal knowledge for controlled usage

The architecture notably includes:

• modular Flask backend separated from the interface
• complete web interface with light / dark mode
• floating widget embeddable on any website
• persistent memory via SQLite with session management
• local browser-side history
• typing effect for natural interaction
• locally editable knowledge base

All data can remain local as long as no external AI is enabled. The architecture supports optional integration through an API key, without requiring any specific provider. The system does not perform automatic learning or maintain global persistent memory, ensuring predictable and controlled behavior.

Building a functional chatbot is not only about connecting an API or displaying an interface. The most time-consuming part is defining a stable, predictable, and maintainable architecture.

This product provides that technical foundation from the start, avoiding the initial structuring phase, uncertain technical decisions, and early rewrites that commonly occur during first implementations.

It allows developers to start from a working, readable structure that can be directly adapted to real-world projects.
