What is FSM-editor?

Finite State Machines (FSM) are fundamental to building reliable chatbots and interactive systems. The FSM-editor provides developers with a powerful visual tool for designing and implementing state machines using ReactFlow's flexible architecture.

State machines help developers model complex behaviors by breaking them down into distinct states and transitions. This editor makes it easy to visualize these states and their relationships, ensuring your chatbot or application behaves predictably and handles all possible user interactions gracefully.

With built-in validation, undo/redo functionality, and an intuitive element palette, FSM-editor reduces the complexity of state machine development. Whether you're building a simple chatbot or a complex interactive system, this tool helps you design, validate, and export production-ready state machines.

Features & Capabilities

This application includes several powerful features that make it easy to create professional fsm-editor applications:

State Machine

Complete state machine implementation with support for states, transitions, guards, and actions.

Element Palette

Pre-built state and transition elements that can be customized for your specific use case.

Custom Shapes

Define custom visual representations for different state types and transition conditions.

Validation

Real-time validation ensures your state machine is complete and follows best practices.

Undo/Redo

Full history management allowing you to experiment freely and revert any changes.

Technologies Used

React
TypeScript
ReactFlow
XState
JSON

Integration

Export your state machines as JSON or code that can be integrated into any JavaScript or TypeScript project. Compatible with popular state management libraries like XState and works seamlessly with React, Vue, and Angular applications. The generated state machines are framework-agnostic and can be used in both frontend and backend applications.
