Stately

Stately | Build complex logic intelligently is a visual development platform that lets you design, simulate, and deploy stateful logic using diagrams, code, and AI-assisted tooling. It combines a drag-and-drop editor, integration with the XState ecosystem, and code generation to serve as a single source of truth for frontend and backend workflows. Designers, product managers, and developers can collaborate in one place—from mockups to executable code—without silos. AI assists across the lifecycle, from prototyping to testing and code scaffolding. Users can preview prototypes instantly, generate React apps from diagrams, and deploy scalable stateful services with minimal boilerplate. The platform emphasizes living documentation, seamless code synchronization, and cloud-backed collaboration, all while supporting robust stateful architectures with XState under the hood.

How to Use Stately

1. Design in the visual editor. Drag-and-drop states, transitions, actions, and guards to model your workflow. Attach assets, descriptions, and requirements alongside states.
2. Simulate and iterate. Run the diagram to test flows, edge cases, and interactions. Iterate until the behavior aligns with your product goals.
3. Generate code. Export or generate executable code in JavaScript or TypeScript, or automatically scaffold a React app from your diagram.
4. Add tests. Generate tests to maintain coverage as your logic evolves.
5. Collaborate and share. Use versioning, living documentation, and embedded assets to keep teams aligned.
6. Deploy and run. Deploy to Stately Sky or integrate with your existing stack (frontend, backend, or services) using the provided SDKs.

Core Capabilities

• Visual editor for building state machines and workflows without heavy coding
• AI-assisted design, variant generation, edge-case suggestions, and code scaffolding
• Generate runnable React apps directly from diagrams
• Generate tests and ensure robust coverage
• Exports in JavaScript/TypeScript and integration with popular codebases
• Bidirectional syncing between code and visualization for productive iteration
• VS Code extension for editor integration in your IDE
• Cloud-backed deployment with Stately Sky for backend scalability
• Collaboration features: multiplayer editing, living documentation, version history
• Embedding assets (images, Figma designs) for contextual state views
• Automatic event catalogs and living diagrams to keep teams aligned

---

How It Works

• Create diagrams that represent state machines, workflows, or business logic using the visual editor.
• Use XState as the runtime engine to orchestrate complex state behaviors across UI and backend services.
• Generate executable code (JS/TS) or scaffold full React apps from your diagrams.
• Simulate, test, and iterate with AI-assisted guidance and edge-case recommendations.
• Export, document, and deploy your logic with versioned, shareable artifacts.
