Intro

What is stately.ai?

Stately (also known as stately.ai) is a collaborative platform designed to build, visualize, and deploy complex application logic intelligently using statecharts and the actor model. It functions as a visual editor and source of truth for engineering teams, leveraging XState—a best-in-class JavaScript and TypeScript framework—to transform code into interactive state machines. By integrating advanced features like an automated xstate visualizer, an xstate vscode extension, and built-in xstate ai features (such as xtate with ai flow generation), Stately allows both developers and non-technical stakeholders to collaborate seamlessly, eliminating silos and keeping architectural diagrams perfectly synchronized with the underlying codebase.

stately.ai FAQ

The actor model treats state machines as isolated entities ('actors') that communicate via events. You should use it when orchestrating complex frontend architectures, handling asynchronous workflows, or executing concurrent backend cloud computing processes where predictable state communication is essential.
