Stately

Visual state machine editor for modeling, simulating, and deploying application logic.

About Stately

Stately is a visual software modeling platform for building application logic as state machines and statecharts that humans can read and coding agents can reason about. Its editor supports simulation, JavaScript and TypeScript code export, GitHub codebase sync, and AI-assisted machine generation, and it underpins the open-source XState library. Teams deploy machines as cloud workflows with Stately Sky and use a hosted MCP server with agent tools.
